How to Format a Write Protected USB Pendrive

Christian Cawley Updated 06-12-2019

You’re trying to save data on your USB flash storage, but there’s a problem. Any attempt to save displays the message that the drive is “write protected”. How can this be?


The drive won’t even allow you to reformat it, and there’s no apparent switch for enabling or disabling write protection. Puzzled? Here’s how to format your write protected USB pendrive and start using it again.

Is the USB Drive Write Protected or Corrupted?

Before proceeding, take the time to make sure that the drive is genuinely write protected. A couple of other issues could be coming into play here.

  1. Your PC’s USB port is defective or blown entirely. Fixing a damaged USB port USB Ports Not Working? Here's How to Diagnose and Fix It USB ports not working? This article explains how to quickly identify the problem and fix it as fast as possible. Read More can be tricky but not impossible.
  2. The flash drive is corrupt. Whether you’re using a full USB flash stick or USB SD card adapter, problems with the device can occur. These steps will help you fix a corrupted flash drive How to Fix the Disk is Write Protected USB Error Is your USB drive throwing up a disk write protection error? In this article, we explain what that is and how you can fix it. Read More .

Confident the problem is just write protection on your USB flash stick? Let’s move on.

How to Remove USB Write Protection With Diskpart

Before starting, insert your pendrive into your computer’s USB port.

Windows has a built-in disk partition management tool called Diskpart. You can open this by hitting Windows key + R, entering cmd, then hitting Enter.


User Access Control will prompt you to confirm the action. Click Yes to continue.

You should now see CMD, the command line tool. At the prompt, enter


A new command line window will open, with a new DISKPART prompt. It’s time to see which disks are attached to your computer:

list disk

The resulting table will list the currently available devices. But which is your USB drive?


Disk 0 will be your computer’s system drive. This is the one that Windows is installed on. If you have multiple partitions, these will be sequentially numbered. Note that the size is displayed for each disk.

With a USB flash device connected, (which will be Disk 1 or higher) you should be able to identify it by its comparatively low capacity.

Find a list of disks connected to your system

In the image above, while Disk 0 is 119GB and Disk 1 931GB (two partitions of the same drive), Disk 2 is 16GB.


Therefore, Disk 2 is the USB flash drive. You should be able to check the capacity on the device itself, as this is usually printed on a drive’s casing. If not, you’ll be able to confirm it in Windows Explorer.

Select the Right Disk!

Before proceeding further, be absolutely certain that you have identified the USB pendrive. Note also that USB flash drives can be as high as 1TB in capacity (like the PNY Pro Elite) at the time of writing, which could be larger than your computer’s HDD. Making the effort to be totally certain at this stage is vital to the integrity of the data on your computer!

Once you’re certain, it’s time to select the disk. In our example, that means entering

select disk 2

This will be confirmed with the message that disk 2 is now the selected disk. Next, request attributes:

attributes disk

Various information will be displayed. Check the first line. This is the Current Read-only State. If you’re unable to write to the disk or reformat it, then Current Read-only State will be set to Yes.

You can easily remove the write protection on your pendrive with the command

attributes disk clear readonly

If successful confirmation of the step will be displayed with the message “Disk attributes cleared successfully.”

Make a USB flash drive readable

Happy to lose the data on the USB flash drive? You can format the drive using diskpart’s clean command. First, ensure the disk is selected:

select disk 2

You can then create and format a partition:

create partition primary
format fs=ntfs

Wait for this to complete—you should now have a fully working and formatted USB flash drive!

Check the write-only status of the drive by copying a small file.

Didn’t Work? USB Formatting Utilities to Try

Below are two free tools for formatting your USB drive in the event of a write protect error. These can be used in addition to, or instead of, Diskpart. Useful if you don’t like getting your hands dirty with the command line!

1. SD Formatter

SD Formatter tool

Number one on your list should be the SD Formatter tool from the SD Association. Although clearly intended for SD cards, the tool is compatible with USB flash sticks. After all, A USB flash stick is basically an SD card wired to a USB interface.

Simply connect the device, select the drive and a formatting option, and click Format.

Download: SDFormatter (Free)

2. Kingston Format Utility

Intended for older Windows systems (Windows XP to Windows 7), the Kingston Format Utility is ideal for USB flash devices from Kingston.

Note that this has a slightly archaic method of installation. After downloading, run the EXE file and hit Browse to select a location (such as the Desktop, or Documents). Click Unzip, then browse to the new location, and double-click Kingston Format Utility.exe.

This will run the app; all you need to do now is select the Device and File system from the drop-down menus. Click Format when you’re ready, then wait.

Can’t Reformat Your USB Flash Drive?

If none of the suggestions you’ve tried so far have been successful, don’t give up hope. It’s worth checking the support pages and forums on the drive manufacturer’s website to find links to tools that have been confirmed to work with the device.

Note that most flash storage manufacturer’s offer a long guarantee on their devices. If you have registered the drive, you’ll probably be able to get it repaired or replaced.

Your Write-Protected USB Pendrive, Formatted

By now you should have unlocked the write protection on your USB flash drive and reformatted it. This may have been done using Diskpart on Windows, or a specialist third-party utility.

Ultimately, you should have a USB drive that now works. If it doesn’t, then there’s a strong likelihood that it is defective. So, if the drive is still in warranty, explore your options regarding a manufacturer replacement.

    write protected error- can't format : my usb transend 4G

    I know it was working earlier i remember that while i was copying files from my pc to this 4gb transcend usb drive, i got no space the files to be copied in full in such way i got error while copying that no space to copy the files. Then in a half way i have to remove the usb. Then i connected again and checked it was full occupied no free space to copy anymore files there. then i tried to delete some of the files and i got this write protected error. from then it was not possiable for me to use that drive. Now after some long gap i tried goodle for this problem to either remove the write protection error or to completely format and use it as a new one.

    I finally got to get cleared and formated it successfully

    after google search i some how reached this link:

    from there you need to download
    1) JetFlash Online Recovery, & Plug in your USB Drive.
    2) Run the JetFlash Recovery software Continue the repair process on screen.. to complete..

    So now i can use it as early i did..

    Hope some one will get helped out of this...

Have tried everything (even the Apacer tool - which doesnt find the drive). Nothing yet. It's still write protected. Still searching.

    Thank you SOOOO much for this article!! I had recently purchased a 32GB USB3.0 flash drive and shortly after I put some files on it it went READ ONLY. I was ready to try the other utilities you mentioned, then I read further about checking out the mfr website - Sure enough, they had a utility to restore it to factory defaults. And it worked!!!! Out of all the articles out there, yours was the only article that suggested that. I would never have thought of it otherwise, and it likely would have gone in the trash (such a shame and a waste!) Thanks Again!!!

    When I tried the command prompt, it said "current read-only state: yes" but then it said, "read-only"no". So is my USB only partly write-protected? Why does it say "no" for the "read-only" instead of "yes"?

    This worked for me using windows 10.

    Go to "Device Manager". Scroll down the "Disk drives“ tab and right click on the USB flash drive's icon.

    Select the "Properties" option from the menu that appears and click on "Policies" tab from the Properties window. Select “Better performance" option button and then click OK.

    Now go to "This PC" and right click on the USB flash drive's icon. Select "Format" and click on the "Restore device defaults" button then click "Start" to start formatting.

    Wait a few seconds for format to finish. Go back to "Device Manager" to change back the "Policies" setting from the USB drive to "Quick removal".


    USB drive is back to FAT32 default setting and no more write protection.

    Sometimes, if the USB hardware is failing, the USB driver controller will put the drive in Write Protection mode to protect the data that exists on the drive so that it can to copied off the drive. The drive is likely unfixable.

    I had the same issue with an SMI USB drive. Fixed it. None of the diskpart, regedit, or any other techniques worked.

    This link was very helpful.

    1. Download this
    2. Use the ChipGenius_v4_00_0026_b2.exe to identify the microcontroller you have on your USB drive (I had an SMI)
    3. Find the microcontroller and download it's manufacturer reset utility. For me this was found here:

    Plugged in the drive and ran the tool. It reset everything...including the write protection.

But it shows the name as SM3255AA MEMORY BAR and the Model number and Manufacturer property shows as unavailable.

    Got a problem with my USB-Drive, I can't write anything in it nor format it, all this because it write-protected itself lol, since it doesn't have a write-protect switch nowhere!
    Can't delete, there's no delete option on right-click!

    Can't format:

    Disk Management says it's healthy, but can't manipulate nothing with it:

    Diskpart fails too, sends 'salute' to event log:

    The little registry trick fails too:

    Tried formatting it through 'Safe Mode with command prompt' failed too!
    Tried many formatting tools and apps, some fail, some couldn't even detect it!
    Tried it on my other Win XP, MAC, Linux, same...
    Tried with some live cd-s fails too!

        Read only:NO

        what it mean??still i didn't get any solution for formating my pendrive

        • Guy McDowell
          January 8, 2016 at 12:52 pm

          That means that the Read Only attribute is set to NO. So you should be able to read and write to your pendrive.

    My drive would allow anything to be put on it. Just heaven forbid if you needed to delete or modify anything! Blasted "disk is write protected".

    I had to use a similar approach to ypz59371.

    The command line didn't work, Disk Management didn't work, and a program wouldn't work. I tried putting in my Windows 7 installation disk to use their partition manager, but that didn't work. I got out my PCLinuxOS LiveCD and some drive manager utility on it said the table was too corrupted to read and that it would have to clear it. Never could get it to format it, but when I booted Windows 7 back up my disk FINALLY allowed itself to be re-formatted. No more "disk is write protected" pop-ups so far and I can delete things again.

    • Guy McDowell
      December 16, 2015 at 1:06 am

      That's weird, but I'm glad it's working for you now.

      Perhaps the partition table being cleared made it possible for Windows to treat it as a fresh, unpartitioned drive. I'm honestly not sure how that all worked out, but still glad for you.

    After I finish with the step 1 in cmd, when I tried to do formatting test I forgot to remove flash drive from my laptop before formatting and now it won't read it. Is there any way to read it again?

    • Guy McDowell
      November 20, 2015 at 8:50 pm

      I don't understand. Did you format your flash drive?

      When you say 'it won't read it' do you mean your computer doesn't see the flash drive?
      Or, do you mean you don't see any files on the flash drive?

      If you can see your flash drive in Windows Explorer, but you don't see any files on it, that's because the formatting erases everything on the flash drive.

      If you have the flash drive inserted, but you can't see it in Windows, I recommend trying the different software utilities like the Apacer and Kingston tools.

      Also, check the manufacturer's website to see if they have any advice or a tool that could help you out.

    i have DT 101 G2 16 GB pen-drive. had same problem. i used a partition tool (AOMEI Partition Assistant) to delete the partition, then used window's disk management to change the drive letter. At last formatted, from same disk management, with volume Level:empty ,File system: exFAT and allocation unit size: 4096K.

    now i don't know what i did out there but its working. no read and write protection. all good. hope this might help someone.

    Apart from above option, I have also tried reformat it through DiskPart and still does not work.

    What works though is the Apacer Tool. Although my thumbdrive is not Apacer, well it works. I have to choose the "Restore" option though, as the "Format" option does not work.

    I tried Apacer USB3.0 Repair Tool on my write-protected (which I believe was actually corrupted) Kingston DT101G2 16GB and it WORKED!

    I have been trying to remove the write-protection for nearly 1 year and I tried nearly everything! Even opening the flash drive to check for lock switches, formatting through cmd, powershell, Linux shell, BSD shell, Baidu shell (that's actually a joke, but if someone said it could work, I'd have tried it)... And nothing worked, except Apacer's tool.

    I tried it once and it worked. I did not even try the format option, for I was quite sure it wouldn't work, so I clicked Restore rightaway and it simply cleaned all the files I couldn't erase and renamed the unit PUBLIC. So I formatted it again to put a name I wanted on it and then tried copying a file to it, reading and removing and it worked 100%.

    The write-protection issue is still a mystery for me. I don't even know how did it happen, so I think it was really corrupted. I believe that when the pen drive controller's firmware gets corrupted, so it shows this kind of weird stuff. Kingston assured me that this model don't have any kind of write protection option except for third-part softwares, so they told me it could be broken or maybe a counterfeit unit, but all the genuine Kingston marks were here and I had it registered... I believe it could have been caused by a malware infection. But now, it's all ok. THANKS!

    I used the DISKPART method. On the attributes list the "readonly" attribute was disabled (Readonly = No) by default. But still I couldn't write / copy any file on my USB Flash drive.

      Did you try any of the other methods? Maybe look into the manufacturer's site to see if they have a tool that would help?

    Alhamd-O-Lillah all my data was SAVED.
    Thank you Guy M.

    I used "Apacer USB3.0 Repair Tool".
    First I copied all the stuff from my "read-only" pen drive to PC.
    Pressing "FORMAT", didn't work. (format failed)
    Pressing "Restore", well! it did the work.
    It was restored to "Factory Default". I copied All my data back and; YEEEEAH :)

      Thumb drive? Can't say I've seen one with that capacity. I have a feeling that the sheer capacity of it might be causing problems. Certain file systems don't play well with larger capacities. Maybe try formatting as NTFS if you only use it on Windows systems?

      I really don't know what to suggest. Sorry.

      Hey Rai,

      If you can give more details, maybe I, or one of our fellow readers, could help you out.
      Error messages?
      Drive make and model?
      Details of what you've tried?
      Details of the computer you're using it on?
      Those sorts of things.

    Thank you so much!

    I too had this problem just the other day and nothing mentioned all over the Web worked, until I came across this article! The Apacer USB 3.0 Repair Tool did the trick, after two days of endless searching. The drive had no write-protect switch, no Windows or Linux utility worked (trust me, I used them all!). The format option of the Apacer tool did not work either, but the restore option did! I was just about to trash the drive and get a replacement and had sworn this was gonna be the last tutorial I'll look at. Thanks to you, my drive is okay and working like new again :)

    This only works if the USB drive is not write protected at the controller level be it firmware related or due to having too many bad blocks.

    • Guy
      April 2, 2015 at 9:49 pm

      Makes sense. At that point, time to get a new USB thumb drive. Prices are dropping every day.

    What about a flash drive with a separate CD part onto it for fingerprints? How does one get rid of that part?

    • anonymous coward
      April 3, 2014 at 10:06 pm

      Hans, depends on the manufacturer of your usb drive. Their might be software the removes it all together such as U3 Software from Sandisk.

      I had one that had a Partition formatted as a "CD drive" and had a catalog on it. GParted made short work of it. Why use the command line on Windows to do it when a Linux GUI app does it quicker? And yes, I am aware of the irony of that!

  165. Kevin

    USB was working fine and suddenly become read-only + when all these methods failed => we should try re-flashing the I/O chip.

  166. jas
    April 3, 2014 at 1:44 am

    I find using Gparted from a USB Linux install works exceptionally well--say 100% in the last six years. It is odd the program isn't mentioned. The HP format tool works almost as well.

    • Guy M
      April 3, 2014 at 11:17 am

      Hi Jas, thank you for the info! I tried to stick to methods that were most likely to be tried by an average computer user. Once we throw Linux in the mix, we've gone into territory that most users aren't willing to tread upon.

      I did try the HP format tool for this article, but it failed in my tests. I have heard positive comments like yours from other people though.

    • Guy M
      April 2, 2014 at 7:30 pm

      Yes and no. The question was if you could format a write-protected USB flash drive. That can be done. It raises the question though, of how to remove write-protection if you can't do it through the normal methods.

      I think if you've followed all the advice given in this article and it's linked articles, there's nothing left but to get a new USB flash drive. In terms of the cost of time, you'd have already spent enough to buy a few new ones.

      hello, i used the given command,now also i am not able to remove the write protection from my usb flash drive.....while formating it is showing that the drive is write protection....what should i do now?
