How to Fix Write Protection Errors on a USB Stick
Pinterest Whatsapp

You’ve finished work for the day. The only thing left to do is stick the files onto a USB flash drive. Then you get this message: “The disk is write protected. Remove the write protection or use another disk.” You immediately pull your hair out. This is your USB stick; you should be able to read, write, and do whatever you want with it!

Okay, you didn’t pull your hair out. You stayed nice and calm. But you definitely need to get your USB drive fixed. Luckily, we’ve got a few simple steps to fix write protection on a USB drive. It’s just technology. We can fix it.

1. Check the USB Drive for Viruses

Every time you plug a USB drive into your computer, you should be automatically scanning it for viruses 5 Ways Your USB Stick Can Be a Security Risk 5 Ways Your USB Stick Can Be a Security Risk USB drives are useful for so many different things, but they can be problematic and dangerous if you don't take the right precautions. Read More — especially if you have used it on a computer that you don’t own, or a public computer. Viruses often act in a manner that will fill your USB drive with nonsense files and this can make your USB drive respond with the Write Protected error.

Depending on your antivirus software, you may be able to configure it to automatically scan a USB drive when first plugged in. If not, you can navigate to the USB drive in Windows Explorer, right-click, and force a manual antivirus scan.

How to Fix Write Protection Errors on a USB Stick Scan USB Windows Defender

If you do find a virus, eliminate it using your antivirus software. At this point, I would advise performing a full system scan after updating your virus definitions. If there is one virus lurking on your USB drive, you never know what might be propagating on your main system.

2. Check the USB Drive Body

Normally I’d make something this simple the first step. However, I’d rather see you protected from a virus, rather than start with the simpler fixes. Some USB flash drives have a mechanical switch on them that puts them into Write Protect mode. This can be a very small slider switch which may have caught on something in your pocket or computer case.

How to Fix Write Protection Errors on a USB Stick USB With Physical Write Protection Switch

If this is the situation, then simply move the switch to the unlocked position and try to copy files again.

Luckily, there aren’t a lot of newly manufactured USB sticks with these locks on them anymore.

3. Check to Make Sure the Flash Drive Isn’t Full

If your USB stick is full, you may also get the Write Protect error message.

Open Windows Explorer, and browse to My PC. This gives you an overview of all drives connected to your system. Right-click your USB drive and select Properties. You’ll be presented with a delightful donut-chart (what was wrong the venerable pie-chart, Microsoft?) displaying your current drive capacity.

But if your USB drive is completely full How to Recover Lost Space on a USB Drive How to Recover Lost Space on a USB Drive If your USB drive ever shrinks in capacity, there's a very simple solution you can use to restore all of that lost space. Read More , it can return a Write Protection error message.

4. Is It Just That File?

Sometimes a single file can upset the balance. Perhaps one file is marked “read-only,” and refuses to be deleted from the drive. This causes an entirely different error message, but it can be off-putting, nonetheless.

Browse to your USB drive, and locate the offending file. Right-click, and select Properties. At the bottom of the panel, under Attributes, ensure Read-only is unchecked.

How to Fix Write Protection Errors on a USB Stick File Properties Read Only

Sometimes single filenames become corrupted. In addition, long filenames are an inherited Windows feature, ingrained in the MS-DOS architecture. The long and short of it is that if a filename exceeds 255 characters, you’re going to have a bad time.

5. DiskPart Command Prompt Utility

Are you familiar with the Command Prompt? 7 Common Tasks The Windows Command Prompt Makes Quick & Easy 7 Common Tasks The Windows Command Prompt Makes Quick & Easy Don't let the command prompt intimidate you. It's simpler and more useful than you expect. You might be surprised by what you can accomplish with just a few keystrokes. Read More Well, you’re about to familiarize yourself a little bit more. Don’t worry, it really isn’t scary, and is the next logical step in our effort to fix your USB drive.

Hit Windows Key + X, and select Command Prompt (Admin) from the menu. Type diskpart, and press Enter (1. in the below image). Next, type list disk, and press Enter. You should see a list of currently mounted disks, like so (2. in the below image):

Make sure you can see your USB drive. Mine is Disk 4. Make a note of your disk number. Now enter the following command:

select disk [your disk number]

Once selected, enter the following command:

attributes disk clear readonly

You’ve cleared any remaining read-only file attributes from the USB drive.

6. Into the Registry We Go

If none of the previous steps have solved your Write Protection error, don’t worry. We’ve still got a few more tricks in the book. Next, we’re going to edit the Windows Registry. If you’re not comfortable editing the registry, I understand. You can skip to the next section — formatting your USB drive. If that step is a little too drastic, I’d advise giving this option a try.

Press Windows Key + R to open the Run dialogue. Type regedit and press Enter. Now, navigate to the following registry location:


Look for a key named WriteProtect.

If it exists, double-click it. This will open the Edit DWORD (32-bit) Value box. You can now set one of two values: 0 or 1. 1 means “Yes, write protect my USB storage devices.” Conversely, 0 means “No, don’t write protect my USB storage devices.” Set the value to 0, and then press OK.

But There’s Nothing There?

In some cases, there is no WriteProtection registry entry. In this instance, we can create a registry key of our own. Check out the short video I’ve made below:

(Something gone wrong? Reset the Windows registry to default. How to Reset the Windows Registry to Default How to Reset the Windows Registry to Default If you've messed up the Windows Registry, hopefully you have a backup. If not, you have a short list of options to fix the problem. Read More )

7. Format the USB Drive

Warning: Make sure that you back up all the files and information from your USB drive to your computer. All data will be lost once the USB drive is formatted.

Formatting the hard drive is a last resort. However, it should make your USB drive able to be read and written to. Prior to formatting the USB drive, determine what kind of file system it already has — NTFS or FAT32. Normally the file system that it already has will be the file system that is best suited for the drive.

Open Windows Explorer, and browse to My PC. This gives you an overview of all drives connected to your system. Right-click your USB drive and select Properties.

How to Fix Write Protection Errors on a USB Stick Windows 10 USB Drive File System Type

Close the Properties window. Now, right-click the USB drive again, this time selecting Format. The Format window contains several customizable options, such as the aforementioned File system, the Allocation unit size, the Volume Label, and the Quick Format option.

How to Fix Write Protection Errors on a USB Stick Format USB Flash Drive

Change the Volume label to something memorable. As we are dealing with a potential hardware issue, uncheck the Quick Format box. That will force the format to do more than just erase files. For instance, if there is a bad sector on this USB drive, the “full” format will return an error.

Formatting won’t take long, but the larger the drive, the longer you’ll have to wait. Assuming there is no physical problem with the drive, your USB drive will be formatted, cleaned and ready to go How to Format a New Internal Hard Drive or Solid State Drive How to Format a New Internal Hard Drive or Solid State Drive If you have a new HDD or SSD, you should format it. Through formatting, you can wipe old data, malware, bloatware, and you can change the file system. Follow our step-by-step process. Read More .

8. But I’ve Got an SD Card

Luckily, the majority of the USB drive Write Protection error fixes listed work with SD cards, too.

How to Fix Write Protection Errors on a USB Stick sd cards

Unlike regular USB drives, SD cards still tend to come with a physical write protection switch. Ensure this is toggled before you panic.

The Take Away

Sometimes, the problem is simple. Sometimes, the problem is difficult. Hopefully, we’ve found you a solution, in either case. If your USB drive issues persist, it could be that something more significant is afoot. In those cases, such as a deleted Partition Table, third-party software like TestDisk can save the day.

Regardless, you’ve got a lot more troubleshooting tools in your arsenal now and should be able to get your USB drives working again, potentially saving you a tidy sum of money, and the pain of losing all of your files!

    Nice tips! My Windows laptop showed the message "the disk is write protected", even when I tryed another card with the same adapter. I tryed diskpart, and also the sd association SD Formatter, but what solved my problem was my old ZTE mobile. I put the card inside it and it was able to format.

    I tried everything on this list, making sure that I double checked it all before going forward. And it's still 'write protected' and showing that it has nothing on it via the bytes when I hit properties. It says 0 bytes used, but also 0 bytes of free space. I am confused. I can't access it at all, it just prompts me to format the USB disk. But... nothing will let me format it because it's write-protected. And nothing works. I even did the Windows+X admin commands and the Registry. Still giving me the run around. Is there a way to fix this USB or is it a lost cause? I don't know how it got this way. It was fine one day and suddenly it's like this.

    I have a write protection error...on an external drive. None of these steps work for me and some I won't try (obviously, I don't want to format and lose the data on my external drive!).

    The problem can be traced back to when the power pack to my old Vista laptop fell down about 2 feet from a shelf on my desk to another shelf. It didn't mess up the power pack (the laptop battery hasn't worked in years and the laptop has been on for hours of use since the issue, no outages). The fall of this power pack interrupted the backup that was working at the time, though I can't fathom why it affected the external drive. It showed as disconnected from the laptop altogether, though I could still access it. When I went to copy files over, it said the disk was write protected. There was no delete command at all for any of the files on the external device. Highlighting files and pressing the delete key did nothing.

    After a reboot the same thing happened. After shutting down and restarting the laptop, same thing.

    The external drive works fine on a W10 laptop. I've made several backups since the issue occurred.

    I'm at my wits' end to figure out what happened. I can still access the external drive on the old Vista laptop, read the files, open the folders, but what I can't do is copy anything over or delete anything. From just the one computer, it's read-only. From the other (W10), it's working perfectly normally.

    One more thing you can do is go into Diskpart as he suggests, then select the disk, then type CLEAN which will remove all partition and attribute information on the disk. This makes it act like a brand new disk

    I went through these steps, in a slightly different order, with a faulty Sandisk Ultra on a PC with Windows 10. My main change was to try reformatting before finding these steps. My PC thinks the drive is write protected, and it appears to have failed during a file copy of some music. For me, these steps don't work, in particular there is not the specified registry key in Windows 10 (Creator ed) on this PC. I've had a couple of drives fail similarly in the past, and it seems that a failure while writing often kills the drive. I blame the USB creators, not the drive makers; as USB drives can't always be help perfectly still. In this case, I think the PC shifted and the mouse mat twisted it enough to break the link and cause an error. I've learned that Flash is like a physical HDD, they break sometimes. My only decision now is simple, do I try for a replacement (I have heaps so can't prove the purchase date), or just wer it and buy another.

    • Gavin Phillips
      August 3, 2017 at 10:36 am

      If the registry key isn't there, you can try creating as per the video, and setting the value yourself. But yes, flash drives aren't rugged, like people think -- that said, it isn't exactly like a HDD, in that there aren't moving parts that break. I'm sure you're already doing it, but purchasing metal cased, all-in-ones drives certainly helps (as opposed to a plastic case, with a USB connection protruding.

      • David
        August 9, 2017 at 7:43 am

        Thanks Gavin,
        I actually have a lot of experience with commercial PC support, in the days of MS-DOS to through to Windows NT. I've also had a micro SD card fail since my post went up. Not bad given that last failure that I recall was 2005, or more likely that was the last failure of a newish flash device!
        But, that isn't why I wrote in again! I have since found one very easy way (for PC users) to rescue all that is readable from dead flash. Fire up a command line and use robocopy, but google it first. Robocopy will retry dead files, and unlike anything else I found (eg xcopy) continue beyond a failure.
        Now, why would I insist you google robocopy first? Becasue it's defaults are set to 1 million retries, 30 seconds apart. I don't think anyone wants to wait THAT LONG, and yes I learned the the hard way. Anyone who doesn't changes the defaults may need to be told use to break out and the do it correctly. I think I used 1 retry and 2 seconds.

      Havent a clue, tried the reg thing, and it didnt even have the entire address for ,e to get to it, it went to storage, but that was it, [storage], the fix had a longer name, and my reg didnt have it, perhaps that is the problem, but i use other divices in all my ports, so that cannot be it, right. what i have, a 64gb microSD [which happens to be SD in size] which is not brand, i have stuff on it, but it has stopped working, wont format, wont delete, wont do much of anything. i want it back, is there a techie solution we may try? perhaps some software soultions to access it then go from there? has anyone tried any decent partitition software, just asking. please anyone, there has got to be a solution to this, right???

    In case people are still having this issue I've tried 10 different ways to get some of my USB sticks to work and they all failed.

    I used Rufus 2.11 and finally got my USB sticks off the write-protection deathloop (they were all SanDisks 4gb - 8gb, 1 Blade, 2 Cruzers)

    A quick Background - I was using them individually to install various OS options, I think Chrome OS tool was the biggest culprit in causing issues with write-protection.

    Anyway, in Rufus:
    1) click the Drop down arrow for Advanced Options - and select the "Add Fixes for Old Bios, (Extra Partitions, align, etc.)"

    2) Set the format type to Fat32

    3) MBR Partition scheme is fine

    4) Select "Create a bootable disk using : MS DOS" (Note sure how important this is but it was working so I didn't try others)

    5) Cross your fingers and click Start

      If you're having problems with SanDisk USBs, be advised that this is a long-running issue with these sticks. SanDisk themselves have no answer other than 'Send it back to us and we'll replace it'.

      Digging around in remote, murky PDFs produced the information that SanDisk purchased a whole batch of USB controller chips from SK Hynix which turned out to be faulty. Hynix wouldn't take them back, or refund the purchase price for the batch.....on the premise that having been soldered into the circuit boards, they now counted as 'used', and their returns policy didn't cover this scenario.

      The Blades, in particular the 8 GB models, are honestly so cheap that they truly have become a disposable item. I've used quite a number of these over the last few years, and never keep anything important on them. For that, I prefer TDK drives.

    I tried to format twice and none of the times worked.
    I tried the other option going to the registry, but i dont hace the "write protect" feature, so there is no way i can do that. I have a desktop with windows10 and a laptop with windows7, on both there is no way of finding the writeprotect file/folder.
    The usb has some mp3 files on it but i cannot add more and i cannot even delete the ones that are on it. It's like it's stuck. No adding, no deleting.

    My case seems to be a little more troublesome... It is an SD card and I found your article through another one talking specifically about SD cards. I found the information here really valuable, but it couldn't help me unfortunately.

    My SD card is write protected in a very interesting, but desperating way. I use it in my phone and it stopped recognising it. It had happened before when I filled it with vídeos (I use my phone as a cheap and more practical dashcam and this day I used it in a long trip. it made like 4 50min videos). I removed the files from it and my phone got back recognising it.

    Everything was going nice and good, but then I used it in another trip and before the trip ended, the câmera app crashed. No big deal, I thought, but at home I discovered that the phone stopped recognising it again. But unlike previously, now after deleting the files my phone still couldn't read it.

    So I put it back in the PC and the files were actually still there! Tried deleting it again, removed and put it back and the files were there... like a Phoenix back from the ashes.

    Tried formatting it, but the Windows native program for formatting says it is write protected (it is not. If it was, Explorer would not even show me the delete and format options). Tried formatting it on Linux using gParted BUT even though it tells me all the steps were finished (erasing the partition and formatting the whole thing to FAT32), when I get to look into it again, it is still untouched like a Highlander SD card.

    Tried all of your suggestions with exception of the registry as it seems I don't have that specific key (maybe a Windows 10 thing not having it?), but since it didn't work even on Linux, I don't think it would help either...

    I'm really upset about this issue as it is a 32GB micro SD Ultra from SanDisk... A quite expensive piece of tech for it's size. Do you have any extra tips specifically for SD cards?

    None of these methods worked. All the way down to re-formatting. I get an error message that states the disk is write protected so I can not reformat the drive. I purchased SIMMAX brand and was in the middle of copying files when the first read only error message showed up.

    None of your options above worked on my Patriot 32GB. FYI: in the final attempt at --> HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies there is no "StorageDevicePolicies" listed on my machine. I am assuming this is item has to be available to make my usb storage device "NOT" write protected?

    Hi Guy McDowell:
    I have a 32Gb Kimtico USB flash memory that gives me that message: your disk is write protected, remove the....bla bla. I can copy the files but it won't let me write into it nor format it, I have already tried all the methods you describe here and in some other sites. As well as many free software to clean, format, reuse, etc, (like disableUSB, HUFFYHUV, jetflash, SDformater, TestDisk, etc. and non of them seemed to have worked.
    Is there any other way to recover my USB, or is there an app that I might buy to do the task?
    Thanks in advance and you can Email me if you'd like.

    Hi, I need help here.

    I have a micro sd card (FAT 32) for my camera and when I try to delete files from computer (I'm using 64 bits win 7), it says "This media is write protected."

    What I've done:
    1. Check for any read-only status, and the result is there is no file with read-only status.
    2. Try to format it, but again. It's write protected.
    3. I try to use cmd command to clear disk read-only file and to clean it but it didn't work.
    4. I try to open Storage Device Policies and change the Write protect dword registry but it's already at 0.

    If anyone know what's the problem and how to solve it please help me. Thanks.

    I completed the CMD but that didn't work. I went into the registry but I could only get to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control the next path wasn't there. There was storage but nothing that could help me.


    Also I can't format it because it says it's write protected. My USB was working fine last week.

    So I still can't use my USB which has all my files on. I have managed to deleted them from my NAS drive last night and this is an older, but not too old version. Really stressed now and have lost a day of work :(

    • Guy McDowell
      June 21, 2016 at 7:47 pm

      The DWORD is a type of value for a registry key. If you're not comfortable working in the registry, I recommend staying out of it. A little mistake can lead to a big problem very quickly when working in the registry.

    I tried all your methods but it didn't work. Just like what you've said, " If your USB drive isn’t listed here, this won’t help you any. You can see in my example below that all that is showing are the two partitions on my computer’s hard drive. My USB drive doesn’t show up in here for whatever reason." So what i did is, I typed "SElect disk 3", But "no disk" was the response given to me.
    Then, i also tried the RegEdit.Exe, yet when I tried to find the "Storage Device Policies". It turns out that it has no "StorageDevicePolicies" instead it was just "Storage". That was available on my disk.

    So please help me with my problem. I don't know what to do. I'm losing hope and a bit frustrated to what had happen, about this "write Protected". Hopefully, you would help me because i don't wanna lose my files which is very important to me. I treasured all those so please i really need your help. Help me please to solve my problem.

    Please leave a message with my accounts.

    I have a Seagate FreeAgent GoFlex Desk External Drive (file system exFAT) which I use with my old XP computer. All of a sudden today I started having problems with saving or backing up to it.

    When I tried to back up my Quicken files, I got this message: "Unable to access the disk in Drive G. Please make sure the drive is ready and the disk is not write-protected."
    When I tried to do "save as" for an Excel file, I got this message: "Cannot save the file. The location you want to save to is write-protected."

    Your advice was very helpful. I was able to remove write protection from my USB device by using the Diskpart Command Line Utility. I am now able to back up Quicken files and save Excel files to it.

    However, when I opened the Seagate properties tried to do error checking and disk defragmentation, I couldn't do either one. The defrag option gave this error: "Cannot run on this volume type" and check disk with the option to automatically fix file system errors, it gave this message: "Windows was unable to complete the disk check."

    In the past both of these had worked just fine. What else should I do?

    Many thanks for your help.

    Hi Everyone,

    I have been to multiple websites, Youtube videos and blogs. All end up with the same advice you provided. None of these have worked. My error happened while copying files tyo the drive. I can access thedata, and copy it off, but cannot modify or add new data. The easiest way to explain my methods is below.

    PHYSICAL CHECK - No switches or buttons (Kingston DT 100 G3 32GB USB3).

    ANTIVIRUS - Was the 1st thing I checked, Avast, AVG, Kapersky, Nortons, Malwarebytes, nothing found.

    DISKPART - It changed the Write Protect to NO, but the "Current Status Write Protect" will not change from YES. (tried multiple little tricks like removing straight away and plugging back in, rebooting, but nothing works)

    REGEDIT - Did not have StoageDevicePolicies. Found how to add this to my editor, but this also did not work.

    FORMAT - Will let me select all the requirements for my format but when click OK, just tells me its write protected. Manufacturer - Tried a Kingston USB3 format tool from their website for this exact product, but the same deal.

    MULTPLE PCS - I build and repair computers for friends, so tried testing on other machines (including all the steps already completed above) and still couldn't get a result.

    In conclusion, I find it puzzling that the drive still works except for the protection, but I can only deduce that it is a hardware fault and that I need to bin it when the data on it is no longer useful (just music and some documents). I have already spent enough time on this that I should have just bought a new one, especially when you work out your hourly pay rate. So if anyone else has this problem, don't keep searching if you've done all of the steps, just let it go.

      Have you tried Linux (Ubuntu or Mint) via a live CD?

      Linux have a disk tool that comes with the linux operating system simply called DISK which you access from the start menu.
      My Kinston USB drive became unmountable after I made it a bootable USB........and I could not format the disk.
      However after firing up the DISK tool in Linux, the tool gave me 2 options.
      1) to delete partition.......or 2)Write a new file system .
      I tried both options...........but no2, "write new file system"..........worked and now my USB stick works as normal again.

    If you're still having problems with your USB flash drive, here are some other resources to try:

    HDD Low Level Format helps perform a very thorough formatting of a drive. Be sure to select the right drive.

    mUsbFixer is a free and tiny tool to remove write-protection and format the pendrives and SD cards.

    Check these articles for additional help:

    How To Format A Write Protected USB Flash Drive
    How To Make Corrupt USB Jump Drives Work Again
    Windows Can’t Format Your Disk? How to Fix It.

    Also, check with the maker of your USB thumb drive to see if they have any tools to help, or advice to give. They may even offer a refund. Here are some links to some major USB thumb drive makers:

    Sandisk USB Flash Drive Support Page
    Kingston Data USB Flash Drive Support Page
    Transcend USB Flash Drive Support Page
    PNY USB Flash Drive Support Page
    Patriot Memory USB Flash Drive Support Page

    If the maker of your USB Flash Drive is not in that list, try searching for them with Google, Bing, whatever search engine you like.

    If you don't mind getting deeeeeep into your USB and some technology you might never have worked with, check out this firmware-based method that might recover your USB drive.

    2 plug in the flash drive
    3 power pc down
    4 boot hitting F8 to come up in DOS SAFE Mode
    5 Format the FLASH DRIVE
    6 power down
    7 Boot to normal windows
    8 IF Windows does not recognize the flash drive, format it again. This will automatically be a 'quick format' (1 minute)

    I had two Scan Disk USB flash drives (32GB & 64GB) that were formatted in the exFAT format that kept giving me the "Write Protected" warning when I tried to change the name of a file or erase a file. I am using a Dell Inspiron 530 with XP installed. I tried these suggestions and others that were similar that were found on the internet but I had no success.

    I then ran check disk on each USB Flash drive and this corrected the problem for both flash drives. I ran check disk by inserting a USB Flash Drive into the computer and then going to Run (under the start menu in Windows XP) and typing in chkdsk e: /r (spacing is important) and then selecting OK. It took about 130 seconds to complete for my 64GB Flash drive. Note: e: is the drive in which my Scan Disk 64GB USB Flash Drive was located.

    I am curious if I was lucky or if this is actually a solution so please post your results so others will know.

      Note: In the above post I used chkdsk e: /r because my USB Flash Drive was using the e: drive. If yours uses a different drive after you inser it, then use that drive letter in in place of e:

    My USB drive suddenly started telling me that the disk is write protected. It has been working fine prior to this msg and now it isn't at all. Someone please help, as I cannot insert my windows disc to make it all go away like Sead has mentioned. Also, I'm using Windows 10 if that changes any steps I would have to take.

    My USB
    1. Doesn't have virus on it,
    2. It is not even full,
    3. All the files are write protected (i've tried the properties and unchecked the readonly, but still failed)
    4. And my USB body doesn't have the write protect switch,
    5. I've tried the CMD, it says that it was successful but it didn't,
    6. I tried regedit but i can't find the StorageDevicePolicies, mine only has storage,
    7. And the last i tried to format it, but it says that it can't be format because it is WRITE PROTECTED

    By the way i am using windows 7, and my laptop is a notebook, so i can't insert a CD like saed adjar said, i was wondering if it were because my chipset usb are broken or maybe it was because i am using windows 7, please anyone do kindly help me, I would be bless, thank you.

    I have a variant how to remove Write protection on your USB Flash drive
    Step 1. insert your CD with Windows XP
    Step 2. insert your USB Flash drive into your PC
    Step 3. reboot your system (keep in mind that you are about to fix the issue about your usb not installing windows XP)
    Step 4.Boot form CD
    Step.5 Press any key to boot form CD.....
    Step 6.Follow the instruction properly till you reach the step on witch partition you like to install windows
    Step 7. Locate your USB Flash drive and delete it
    Step 8. Reboot your system
    Step 9. When your system booted to windows go to my computer right-click click to manage
    step 10. go to disk management and repartition your USB to normal condition and format with FAT32

    Done!!!! you have fixed the issue with your usb flash drive

      .tmp is a temporary file. It might get created whenever you plug in your USB flash drive. Temporary, or temp, files are little system files where things like variables and other settings get written to.

      Once whatever application needs that info is done with it, it sometimes gets erased. Depends on what's using it.

      You don't see them much because they are often hidden from view as either hidden or system files. Maybe you have View Hidden Files turned on in your Windows Explorer.

      It's nothing to worry about.

    Your files are garbage. I ran through all of your steps, clicked through your links and no solution. This is a brand new thumb drive that I just wasted hours transferring data onto, ejected it, inserted into a new computer to have Windows tell me it is write protected when I never chose to do so.

    Clearly you know as little as Windows as to why this is happening so thanks for nothing.

    Could be that you're trying to copy a file larger than 4GB to a FAT32 formatted drive. That's what the problem I was having was, and you'll need to format it to something other than FAT32 to fix it.

    Flash sticks have become pretty cheap in the last few years and I agree with Guy. "Don't spend a lot of time trying to fix one - just buy a newer "bigger and better" one if the simple solutions don't work." Usually if the simple ones don't work it probably means the device is toast anyway and you are just trying to chase your own shadow.

    These devices don't make good backups so don't rely on them and assume the data you copy to them is %100 save - it's not. If it's important data keep an extra copy on a separate flash stick. I have seen too many of these devices fail and it always seems to be at the most inappropriate time.

  140. Haster
    November 30, 2015 at 2:30 am

    I purchased a 32 GB USB drive and suspected that it was a fake because of the cheap price. So I used a very common testing program from Germany (forgot the name). Don't use the testing program. The testing program corrupted the drive and it became unformattable. Prior to that, it was possible to format the drive. The testing program tries to write into locations outside of its address range, and I suspect it wrote into the programmable logic.

    The USB drive indeed had a problem with FAT32 folders and broke its own file system when writing on multiple folders, needing reformatting. However, it could actually store 32 GB, if there were no folders and subfolders. I suspected a problem so ran the testing program, which corrupted the drive and now I cant format it.

  141. Masamune
    November 30, 2015 at 1:55 am

    None of the methods worked for me. Although I suspect it's because of the age of my flash drive (At least 7 years).

    I think i've read about it somewhere that a flash drive can only be written on for a finite number of times. Somewhere within the thousand range. After that, you won't be able to put files into the drive, but you can still read the files that was inside it.

    My flash drive is pretty much like that. I could use it to play the music in it days ago but yesterday, however, I formatted my drive and it became write protected. So yeah. Just though it might be worth mentioning.

  142. Haster
    November 29, 2015 at 9:29 pm

    Everyone here is reporting that these suggestions don't work. Problem is that the drive is not formatted. But when trying to format it, it says write protected. The bios on the drive seems to be corrupted.

    • Guy McDowell
      November 29, 2015 at 10:30 pm

      I've offered some approaches for a problem that could be caused by a multitude of issues.

      These approaches have helped some people but not others. No one article could comprehensively address all possible causes.

      If what I've offered doesn't solve your specific problem, feel free to move on. There are thousands of articles out there. Surely one of them will assist you better.

      • Haster
        November 29, 2015 at 10:48 pm

        Fair reply. But I think my problem is pretty common and that is what drives people to search for a solution on Google. Most of the comments below are referring to the same problem - unable to format an unformatted drive. And we don't know who the manufacturer is. Is there a way to find out?

        Is it the case that USB drives or flash cards have a piece of programmable logic or firmware that can get corrupted, hence making them unformattable?

        Given your extensive knowledge on such matters, I would think you can shed some light on this pressing problem.


        • Guy McDowell
          November 30, 2015 at 5:07 pm

          I think the specific subject is worthy of a new article.

          Adding on within this article is a bit of an editing nightmare.

          On USB flash drives there are two main parts: a controller and the flash chip.
          One or both of those could be damaged physically. Configuration and firmware could be corrupted as well.

          The process of fixing those has a pretty high likelihood of rendering the drive unrecoverable. That's why I recommend getting a new one if the fixes in this article don't work.

          If you want to fix it for the fun of trying, it might be worthwhile. If you're trying to fix it to save money, you may have already spent enough time to have earned the money to buy a new one.

  143. Haster
    November 29, 2015 at 9:26 pm

    The problem is that there seems to be some kind of bios on the flash drive. If this bios is corrupted, then nothing by Windows works.

    Where I can find a piece of software to reset the bios on the flash drive?

  144. Haster
    November 29, 2015 at 9:23 pm

    The reason I want to write protect is to be able to insert my pen drive into public computers without the pen drive being infected with viruses. I give lectures at university and most computers are infected. I have managed to write protect using the attributes set readonly command but it will only protect my pen drive on the computer I have enabled write protect. Is there a way to write protect it for all computers.?

      November 14, 2015 at 5:47 pm

      In Windows Explorer, select your USB drive.
      Right-click on that drive and select Properties.
      In the new window, click on the Security tab.
      Select the user Everyone and click on the Edit button.
      At the bottom of the resulting window check the boxes in the Deny column next to Full Control, Modify, and Write.
      Click on the OK button.

      Now that drive cannot be written to from anyone, including yourself. To undo that, just follow the same steps but uncheck the Full Control, Modify, and Write boxes.

          You can create that folder. But I get the feeling you're not an expert with the registry, so maybe you should try something else.

          Working in the registry is tricky business. It can make your Windows inoperable and force you to reinstall it.

      Hi Umer,

      It's probably time to say goodbye to it.

      My rule of thumb for when to give up on something like this is time to fix multiplied what I make an hour. When that becomes more than it would cost to buy a new one, it's time to get a new one.

      If the flash drive costs $20, and I make $10 an hour, I'm not going to work on it for more than two hours.I might work on it longer if there are critical files on it, but not much longer.

      Just a different way to look at it. Hope that helps somehow.

          Have you tried calling or writing to Kingston? If the flash drives are that new, they are probably still under warranty.

          Kingston Data USB Flash Drive Support Page

          Another thing to look at is if your USB ports are providing too high or too low voltage and amperage. Is it possible the USB ports are damaged and that is causing damage to the flash drives? To get you started, review my article, Dead USB Port? Here’s How to Diagnose and Fix It!

          Also check for viruses, malware, etc. on your computer that may be affecting the USB drives.

    The DISKPART stuff all works! Well, it says it does. When I go into regedit: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control

    I have no \StorageDevicePolicies. So even though I've created that key and the Dword (WriteProtect) within it, still no luck!

    I started to do a full format and it got to 3% but had to leave my computer. When I came back it said it was write protected (after a few hours of leaving the computer).

    my USB drive is full. I am trying to copy to a larger USB but I am getting the write protected error and it will not copy the files. The article mentions this can happen but nothing suggested works. Any advice? Please keep in mind I am a novice when it comes to computers.

    Tried all the above steps but unfortunately none of them worked. I think it is time to drop this USB stick in the bin and buy a new one. A shame as it worked well until I used a file rescue programme to rescue and download files from a Mac Pro, then it all went pear shaped.

    Hi. my name is Nnamdi. Some days ago, i tried accessing the contents of my flashdrive, but i kept getting the "this disk is write-protected" reply. But i was able to remove the protection through the help of search results from google

    Now i have a memory card containing videos that i wouldnt want to be sent to anyone throiugh bluetooth or computer explorer. Is there a way i can write-protect this memory card too???

    • Guy
      April 8, 2015 at 12:27 am

      Write-protecting the card won't prevent anyone from seeing the files that are on it.

      Look for ways to password protect and maybe even encrypt the card. There are several different ways to do this.

    I have an USB Storage from manufacturer Patriot Memory where Windows everytime said that it is write protected.
    After browsing the internet for help I don't have found any functional solution to disable the write protection.
    On the manufacturer website I've found a tool to format/restore that fortunately works fine.
    I've choosed the option restore an the tool has deleted all contents an formated it.
    Now my usb-sticks works fine.
    My next stick will be again a Patriot Memory :)

    Try to find a similar solution for your stick :)

    I was having the same write issue with my flash drive.. my file system was also set to RAW.. I tried using diskpart with no luck. I downloaded the program 'HDD Low Level Format tool ver.4.40'setup which can be found here:

    Run the program, select continue at the first box (unless you want to donate money) and then select the flash drive on the next screen and select continue. Next, select the tab named LOW-LEVEL FORMAT and click the FORMAT THIS DISK button on the bottom.

    After it finished running, my disk was converted back to FAT32 and had no read-only attribute. I was then able to convert it to NTFS with no issues. Hope this helps!

    Well, that skimmed the surface, however for drives that are really fubar it didn't make a scratch. Also there were no comments on initializing the drive either, which did help me get the sad little stick to "look" like it was WR, however it isn't . There's a 12MB partition on it that just won't go away. I've dealt with encrypted disks, been all over diskpart and other utilities and it just won't reformat, re-initialize, etc to a usable form. Maybe something did go bad on the stick, however as we're having problems sometimes with the encrypted OS going RO, I'm thinking it's related. Oh well, back to searching.

    Hi, I've been happily using my Kingston dataTraveler USB for months when all of a sudden I couldn't write to it any more. A week or so back I reformatted it as NTFS as I needed to backup some big files (6-7GB) and it seemed to work fine until yesterday. I tried your steps 1-6 (1-5 made no difference) but when I got into the registry settings there is no StorageDevicePolicies listed at that where the problem lies? I'd be grateful for your advice!

    It is new, but tossed the darned receipt away (STUPID). I have checked Scan Disk's site, and sent them an email. They replied a day later (OMG!! so quick). It seems from the email that they too believe the "...USB drive has gone bad and needs to get replaced." They are willing to replace it at their expense, including shipping. Holy Moly a company that stands by their product and will replace if faulty!!!!!

    Have tried ALL you solutions to remove the write-protection (not just file write protection): diskpart in command prompt, regedit (had to create the StorageDevicePolices folder), format quick/format non-quick. NOTHING works.

    The flash drive is a ScanDisk Ultra 32 G and BRAND-flippin-NEW. It's not full, no switch, and JUST started acting up when I was copying files from my hard drive to it.

    I want to delete the data on it, but shy of complete incineration (and the disgust of $60 wasted), I can't get the puppy to un-write-protect.

    HELP, PLEASE!!!!!

    • Guy
      February 8, 2015 at 3:47 pm

      Hi Becky,

      If it's new, maybe return it for a refund or replacement. Maybe it's a manufacturer's defect.

      Have you checked SanDisk's website for any utilities that might help? Or support information?

    Nice article but nothing worked to many users!

    Even when you tried to format your USB Key it didn’t allow you saying “the disk is write protected”!
    I have had the same problem and I RESOLVED IT ! The problem is very dilated, you know for it, but may be also manufakturers of yours USB key knows for it? I have 4GB USB Key Transcend and I found a Tool "Restore/Format" write protected USB Key on their site. With it I succefully formated my Key. i suggest you to look in the site of your manufacturer for the tool or ask them for help.

    WARNING: Make sure that you back up all the files and information from your USB drive to your computer. All data will be lost once the USB drive is formatted.
    Very glad if I help you, yours Zdenko (73 years old)

    • Guy
      February 4, 2015 at 2:22 pm

      Thank you Zdenko,

      It's always a good idea to check the manufacturers website to see if they have any tools that might help.

      That might not be mentioned in this article or it's comments, but it is mentioned in a similar article on our site How To Format A Write Protected USB Flash Drive.

      Again, thank you for mentioning checking with the manufacturer.

Please help me out.

    • Guy
      January 30, 2015 at 6:51 pm

      Hi Burhil,

      Check to see if the maker of your micro SD card has some sort of utility to test it with.

      Sometimes if we don't eject the USB device or SD card prior to physically pulling it out, this sort of thing can happen. Is it possible that's what might have happened?

      Occasionally, putting the card back in the laptop, then following the proper eject card procedure, the card might be made useful again.

      Have you ever worked with a Live Boot CD before?

      Justin Pot has an excellent article called Parted Magic: A Complete Hard Drive Toolbox On One Live CD that will show you how to use this.

      Welcomed newcomer, Gavin Phillips has a great article on the 5 Best Rescue Disks For A Windows System Restore. It highlights some other Live CD utilities that might help you check the health of the USB thumb drive from outside of Windows.

      Each of these Live CDs or Rescue Disks have utilities for formatting that may work better than what you can run in Windows. It's worth a shot. Especially if it's an expensive USB drive.

  216. Terrance Sweeney
    January 25, 2015 at 12:19 am

    None of the processes worked. My operating system is Vista and no matter what I did I could not remove the "read only" or "write protected". I followed the suggestions, the Cmd window would open but no matter what I typed it always displayed the descriptions of the action words. When I tried to remove the "read only" on a file it again displayed the file is "read only". I got the same results when I tried to Format. I have no idea how to solve this which is very frustrating as I have the same problem with 4 other flash drives.

    • Guy
      January 19, 2015 at 5:58 pm

      Hi Lucia,

      If the KEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies does not have the WriteProtect key in it, you can create that key.

      Make sure you backup a copy of registry first, and be sure to set the WriteProtect key value to 0 (zero), which means “No, don’t write protect my USB storage device.”

      Properly eject your USB flash drive, plug it back in, and check if it is still write-protected. Hopefully, it won't be.

      January 8, 2015 at 12:29 pm

      Hi Nitin,

      I'm sorry to hear that you weren't able to remove write protection.

      However, before you judge this article so negatively, you may want to consider what lead to having the write protection error in the first place. I can assure you, it had nothing to do with me.

      Issues like this are almost always the result of what the user of the drive does. Do you just pull the drive out when you remove it, or do you follow the proper ejection procedure? Even if you don't do it properly just once, it can cause this issue.

      Did you put the write protection on in the first place? If so, then it's there because you put it there, not because the plethora of advice you got for free didn't happen to be the solution for your situation.

      And there is one step you haven't tried. Give up on that drive and get a new one.
      Sometimes things are just plain broken and you have to move on.

    Hi there! Im using 4gb micro sd card in my android phone. It reads perfectly. however, it fails to write anything at all. I tried to format it but it failed. I followed the given procedure here in totality and i was at last successful at formatting it. However, I was astonished to see the same data on the card a moment later. I scanned my card under HDtune and it was perfect. I then deleted the partition and formatted it again but the data just keeps appearing back again. Even I tried low level formatting, yet it failed and data appeared again. Not only done the procedure using the phone's connectivity but also various card readers. Can any technocrat please help me to solve this issue? I will be very thankful.

Now it is no showing in My Computer it is showig only in "ComputerManageDisk Management " and in Windows XP installation setup. But XP is not able to delete the partition. Now what should i do, help me please....

    • Guy
      December 30, 2014 at 2:10 pm

      Hi Azam,

      If it is showing in Disk Management, check the drive letter. It may have decided to use a drive letter in use by another device. You can change it to just about any letter.

      I'm not sure what you mean by 'not able to delete the partition'. Did you create a partition on your USB flash drive?

      In Disk Management, does it say that the file system on the USB flash drive is RAW, NTFS, FAT32, EXT3, etc?

      If it is anything BUT FAT32, try changing the file format to one of those. Depeding on the size of your flash drive, you may need to adjust the cluster size. Here's a little bit about FAT32 cluster sizes, courtesy of

      The FAT32 file system can support drives up to 2 terabytes in size (in theory) and because it uses space more efficiently, FAT32 uses smaller clusters (that is, 4,096 byte clusters for drives up to 8 GB in size), resulting in more efficient use of disk space relative to large FAT16 drives.

      FAT32 file system cluster sizes

      Partition Size Cluster Size
      0M to less than 260MB 512 bytes
      260MB through 8GB 4,096 bytes
      8GB through 16GB 8,192 bytes
      16GB through 32GB 16,384 bytes
      32GB through 2TB 32,768 bytes

    Followed all directions above, used two different computers, one laptop running windows 7 home pro 64bit and one desktop running windows 8.1, my usb drive is still write protected. I tried the HP USB Disk Format Utility and EaseUS, neither worked. There is no physical switch, slide, knob, or button on the flash drive other than the one that slides it in and out of it's decorative/protective case. I can not format the drive because I get a message saying it is write protected. I tried taking ownership of the files on it, that worked but still could do nothing with them because the drive itself is write protected. I have been fighting with this drive for months to try to regain control of it so I can actually use it. It's a 64GB drive that currently has approximately 2GB of data on it. I was using it for movies to watch on my WD TV box (not the current model displayed on their website but this one

    Sounds all quite interesting. However my USB flash drive is still write-protected although I proceeded according to above instructions. There is no 'StorageDevicePolicies' in my HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControl
    My operating system is Windows 7, 32-bit. So it would be wonderful to get instructions how to get 'StorageDevicePolicies' in my registry. It should be between: 'Stillmage and SystemInformation'.

    I was on registry step 6 but when I foloowed the instruction there was no option called "WriteProtect". But my USB is still write protected it gives me that erorr message.
    and look for a key named WriteProtect."

    I can't even format it because of the write protection error.
    This means whatever I put into the USB I can never delete. I have backed up my USB though.

    None of steps worked for me. I even created StorageDevicePolicies key and added the flag. Again, it did not work either. I had never been this much frustrated with Windows till now.

  244. Jon Pawson
    October 20, 2013 at 6:48 pm

    None of these steps worked. In particular, in Step Six 'StorageDevicePolicies' isn't there. I tried everything else to no avail. I should probably throw the drive away, right? They're inexpensive nowadays, I don't know why I'm bothering to go through all this work.

    • Guy M

    I tried everything here and still my USB is write protected. I can't even format the thing! I created the StorageDevicePolicy key in my registry but still no go.

    In diskpart when I do the "attributes" command it shows that it's not write protected but that it's "current status" = write protected (that seems more than a bit contrary).

    I'm not desperate to have a 16 GB USB...went and bought another - I just want to fix it because it's bugging me *lol* Any help would go a long way toward soothing my psychosis - thanks!

    Trying to insert window 8 in flash, but it turned to be writeprotected, no a single method that can solved beside buying new flash...................... It is just little error but turn to throw the 8Gb flash away. Amazingly, How come? for this little mistake. After all thank you for the article, and it can't help.....

  256. Flappie
    September 16, 2013 at 1:54 pm

    I solved this by adding the StorageDevicePolicies key to the registry in W7 and only by doing that (and a format with Windows Computer Management cause It wouldnt show in Explorer otherwise...) So, good Guy M, it might be an excellent idea to add a small howtoaddthattotheregistry to Step 6. Thanks for pointing me in the right direction!

    September 16, 2013 at 12:49 pm

    all step didn't worked for me either...
    i can't format it in every way and every site show me....
    still "write protected"
    i use bitdefender though but didn't find any malware or virus....
    4 days ago i copied files to my pc... after i copied the files, the usb flash drive turn "write protected" i check bit locker, but bitlocker is turned of on my usb....

    September 13, 2013 at 5:18 pm

    @ GuyM I tried all the above steps given by u but still getting the same problem. Is there any other way of removing this??? Or should I do the same procedure from the laptop which originated this problem???

    • Guy M
      September 13, 2013 at 7:32 pm

      If there is another way, I don't know what it is. Sorry. Doing this on the original laptop shouldn't make a difference. Maybe if one was Windows and one was Mac, but even then I don't think it should make a difference.

  259. Eashan
    September 12, 2013 at 3:08 pm

    • Guy M

    I followed the seven steps for clearing a write protected flash drive. Step 6 in the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies di not have the entry "StorageDevicePolices". Even did a search for it. No dice. I am using Win 7 and flash drive is recognized.(seen) but, I just can.t touch it. It didn't list it through Regedit. In trying to format it in windows, it tells me it s write Protected.

    I had this problem and tried all of the options mentioned in the article with no avail. I temporarily got write permissions with the diskpart command then I had had to make adjustments in the security tab on the properties section of the drive itself. Somehow the owner had been changed with many of the permissions changed as well. I believe one of my kids was to suspect not sure though.

    • Guy McDowell
      May 14, 2013 at 6:30 pm

    Some times the pendrive can go into RAW format. You cannot format it and when you try to, Windows will display 'Write Protected. Cannot format'

    If you pendrive was working fine till it became RAW, try to format it using EaseUS partition master home edition. Pretty neat software!

    Very good article indeed. Thanks a lot Guy!

  282. Curt Schroeder
    May 14, 2013 at 9:43 am

    You missed a step. You should run "chkdsk /F" on the USB drive before resorting to a reformat, especially if you write to a FAT32 USB drive with both Linux and Windows.

    • Guy McDowell
      May 14, 2013 at 4:17 pm

      I was thinking I was going to do that, but that isn't so much to check for Write Protection as it is for working on a USB drive that may have corrupt files. Good call nonetheless.

      I covered how to do that in How To Make Corrupt USB Jump Drives Work Again.

    File manager does not recognize the drive.
    Disk Management recognizes the drive is in place, but does not assign a letter, nor can I click on the drive - Disk 6 in this instance - in the uper screen, although the drive shows in the lower window with only the size, 59.77 GB, which is identical to a similar drive. It sees the space, but will not allow any further action. Appears I'll have to use gparted or similar in order to fix. Shouldn't have to reboot, nor to use a foreign tool, to fix a Windows drive.

    • Guy McDowell
      May 14, 2013 at 4:15 pm

      Did you unplug any other USB drives? Might the USB drive you want to work on have the same drive letter as something else? That does happen.

I tried everything I knew even did research and ask for help online in the past months but no one seems to have the solution. After reading this article I decided to give it a try again but unfortunately none of the methods seemed to work. I did manage to discover that the folder which contains an ISO fie stored on the flash drive is wright protected, however when I follow the instructions given in step 4 and 5 that doesn't remove the wright protection because when I attempt to remove the wright protection from the folder it give the error message "An error occurred applying attributes to the file: The media is wright protected.
