We keep a lot of data on memory cards and USB drives. Often, you might even use a high-capacity USB drive as your primary way of creating backups The Best Backup Software for Windows The Best Backup Software for Windows Your data is fragile – it only takes one small accident to lose everything. The more backups you make, the better. Here we present the best free backup software for Windows. Read More .

When something goes wrong with them, it’s hard not to feel a sense of dread. Is that photo of your dog falling in the swimming pool gone forever?

But alas, you shouldn’t panic. There’s a high chance you can recover your data – you just need to methodically work through few troubleshooting steps.

Follow along with this article, and you’ll be laughing at your dog again in no time.

1. Check the Basics

Okay, I know this sounds simple, but have you performed some elementary troubleshooting steps?

For example, have you tried your memory device in a different port or on a different computer? Have you given it a little wiggle to make sure all the connections are touching each other?

Sorry, but I had to ask… Now, let’s take a more technical look at the problem.

2. Change the Drive Letter

If you plug your USB stick into your computer and can see the drive in File Explorer but can’t access the data, it’s easy to jump to the conclusion that the data is corrupted.

But hold up. That might not be the case. Windows simply might not be able to assign a drive letter to the stick.

Thankfully, it’s easy to change the drive letter. Open the Start Menu and type Disk Management. On the results page, select Create and format hard disk partitions.

Locate your USB stick in the list of drives and right-click on it. Choose Change Drive Letter and Paths.

Finally, click Change and select a new letter from the drop-down menu. Every time you connect your drive, it will use the new letter.

If you still can’t access your files, keep reading.

3. Reinstall the Drivers

Your USB stick and your data might still not be at fault. Instead, it’s possible that the drivers on Windows have become corrupted.

To be certain your drivers are working and there aren’t any underlying issues, it makes sense to reinstall them How to Easily Remove Old Drivers From Windows How to Easily Remove Old Drivers From Windows Not only does Windows retain previous driver versions for current devices, it also stores drivers for devices you stopped using long ago. We'll show you how to clean up old drivers from your system. Read More .

Leave your USB stick or memory card plugged into your machine and open Device Manager. You can find it by right-clicking on the Start Menu.

Once Device Manager has fired up, click on Disk Drives to expand the menu. You’ll see a list of all the drives connected to your machine.

Right-click on the name of the memory device you’re trying to fix and select Uninstall device.

Next, you need to remove your external drive Do You Really Need to Eject Your Flash Drive (or Device) Before Removing It? Do You Really Need to Eject Your Flash Drive (or Device) Before Removing It? It's well known that USB flash drives are supposed to be ejected before removing them. But do you really still need to do this? What happens if you don't? Read More from your machine and restart the operating system. When the start-up process is complete, plug the drive back in. Windows should automatically detect it and reinstall fresh drivers.

Can you access your data now? No? Let’s keep trying.

4. Check the Disk

At this stage, it’s starting to look like the files themselves are corrupted. But don’t lose hope, you still have options open to you.

There are two ways to check and repair the disk. You can use Windows Explorer, or you can use Command Prompt.

Using Windows Explorer

Firstly, let’s look at the process using Windows Explorer. It’s the more user-friendly of the two approaches.

Plug your memory device into your PC and open the Windows Explorer app. Head to This PC and right-click on the name of the drive you’re trying to fix. You need to select Properties from the context menu.

On the new window, select the Tools tab. In the Error Checking section, click on Check. Windows will scan the drive and report back with the results.

If it finds any problems, another window will pop up to alert you. Select Repair drive to start the fixing process. It could take some time, depending on the size of the drive and the complexity of the corruption.

You will see an on-screen confirmation when the scan is complete. If you click Show Details, Event Viewer will provide you with a complete log of all the repairs undertaken.

Using Command Prompt

The other way to scan your disk and fix errors is to use Command Prompt.

To get started, open the Start Menu and type cmd. You do not need to open the app as an administrator The Fastest Way to Open an Admin Command Prompt in Windows 10 The Fastest Way to Open an Admin Command Prompt in Windows 10 At times, everyone needs to open an Administrator Command Prompt. Don't waste time -- use this super-convenient method to get to it faster. Read More .

Type chkdsk e: /r and press Enter. If your memory device is not using the E:\ drive, replace e: with the appropriate letter.

Windows will give you basic information about the drive and start the scan. You can see the progress of the scan in the window.

Once finished, it will show you its findings and list any repairs it undertook. As you can see from the image below, in my case, the drive was error-free.

5. Third-Party Apps

If you still can’t retrieve your files, you could try using a third-party app. If you do a Google search, you’ll come across lots of fancy-sounding expensive apps. You don’t need them. Try one of these three free versions instead:

  • TestDisk and PhotoRec: Technically, these are two separate programs. However, they’re bundled together because they heavily rely on each other. PhotoRec can recover files (including more than 200 file formats), TestDisk can recover partitions on disks.
  • EaseUS Data Recovery Wizard: This app works with hard drives, SSDs, USBs, memory cards, and digital cameras. It can recover data in a number of scenarios, including corrupted drives, partition loss, accidental deletion How to Recover Deleted Office Files How to Recover Deleted Office Files Lost a crucial file and need to get it back? These tips will help you recover your Office documents in no time at all. Read More , and drive failure.
  • Recuva: Recuva works with USB drives and other external media, as well as your primary hard-drive. It specializes in deleted files, but can also help recover corrupted files.

6. Take It to a Specialist

If all else fails, take your drive to a specialist shop. They might be able to use more powerful equipment than you have access to at home and salvage some data, if not all of it.

Check on Google for a shop in your local area.

What Approaches Do You Take?

I’ve taken you on a step-by-step journey through the most common ways of recovering data off a corrupt memory card or USB stick.

Let’s recap:

  1. check the basics
  2. change the drive letter
  3. reinstall the drivers
  4. use Windows’ Check Disk tool
  5. try third-party apps
  6. take it to a specialist

    If I may ask... how are all of the comments on this article way (in some cases many many years) before the post date of the article?

    I also am not a fan of the fact that this post is only referring to windows, because there are many better ways to recover the data, but that's another story.

    The only tool that actually worked for me (I tried 10 different products) was uFlysoft Data Recovery. The trial version lets you run it to see if actually works before you have to pay for it. I tried another 5 free packages, none of them found a damn thing. Two of them couldn't even recognize the SD card. Recognizes these file types:
    Picture Formats: JPG JPEG TIF
    Video Formats: AVI MPG MOV MPEG ASF MP4 3GP MTS
    Audio Formats: MP3 WAV
    RAW Image Formats: Nikon NEF, Canon CRW and CR2, Kodak DCR, Konica Minolta MRW, Fuji RAF, Sigma X3F, Sony SRF, Samsung DNG, Pentax PEF, Olympus ORF, Leica DNG, Panasonic RAW and more

    Even though this was written like 7 years ago, it still completely works. It recovered my phone's files from my sd card with no problem! Last time I don't backup my files though.. For anybody else who comes across this, right after I typed in "chkdsk {drive}: /r" I got this message:

    "Unrecoverable error in folder \.android_secure.
    Convert folder to file (Y/N)?"

    Now I'm not a computer guru so I have no idea what to do and it scared me all over again, but it didn't sound good so I said "N". It only popped up with one random file address (having to do with the shazam app) and said said complete, much different than the screenshot in this article, so I thought for sure my files were beyond repair. However, when I opened up my card, every file except the \.android_secure and the shazam app cache was back! Perhaps it was one of these files that the corruption was caused by to begin with?

    Anyways, end of story, it works even if it works slightly differently, try it, and thanks so much for being smarter than me and sharing it!

    I tried this method, and it somewhat worked. Chkdsk detected the corrupt file on my usb, and I chose to save lost chains into files, but it turned the entire folder into a single file which none of my programs can open, without getting weird translated gibberish.
    Is there anyway to reverse Chkdsk? Please help me!

    Notice: His file E: was corrupted and in the command prompt he wrote "Chkdsk e: /r" so be sure you're using the correct drive on your own computer. It's not the same for everyone! Hope this helps.

    My USB Flash drive (1 PQ1 USB3) suddenly is not being recognized by my laptop (and any other computer). I tried the above but nothing happens, is there any other way to recover the data in it. I just need the files badly and it is so unfortunate that I was not able to back-up the files for a few days. By the way, when I insert the USB into the pc, the pc can see that it is inserted but could not open it and could not see the files either. The light in the USB keeps on blinking and does not want to stop. Any help will really be appreciated.

      -Disk Utility ( in the Utility's folder ) -click the Drive -First aid tab -repair if that doesn't work, borrow somebody's Windows system as it does a better job sometimes.

    After following this trick, the cmd screen completes with saying that it has found no problem in my disk. There's definitely a problem! So this one doesn't resolve it for me :(
    FYI, my problem is that my phone and laptop do recognize the disk, can see the files in it (file name, file type, size), but when the file is opened then error message comes out (depending on the program which opens it) saying unsupported file type.
    Please help :( :( :(

    This command used to work for me ( Chkdsk e: /r)... However, I've encountered a new prompt saying "cannot open volume for direct access" in CMD... does this mean that my SD is now completely busted and inaccessible?

    Hoping for your response. Thank you, Karl.

    Losing data from a damaged memory card or USB drive is very common nowadays. But you need to employ Remo Recover software to restore them without difficulty.

    What if my card is scratched and is not recognized by my PC but recognized by my phone ( it recognizes that it is a corrupt card but cannot access it). I need to know if there is a way to access the card. I have a lot of pictures that hold special meaning to me that I cannot afford to lose.

      If it was mine, I'd cancel the checkdisk and run either the demo of GetDataBack or the FreeUndelete program I mentioned earlier. I've had great success with them.

      Of course, if there is a fatal hardware issue (damaged memory chip, scratched platter, etc), then there's not a lot a person can do on their own to retrieve whatever was in that area of the data storage. You should be able to recover other areas of data, tho.

      GetDataBack: runtime.org/
      FreeUndelete: officerecovery.com/

      HTH!

    I've never used CheckDisk, as it always seemed to be intent on just truncating damaged files. I've lost so much data due to that silly program...at least this was back in Windows 2000.

    Anyway, I used Runtime Software's GetDataBack just this last year on a trip to salvage a whole memory card worth of photos that someone accidentally formatted. CheckDisk would not help with that at all. There's also a decent program called FreeUndelete by a company called OfficeRecover, IIRC. GetDataBack costs $, but it is has been a super program for me. I definitely avoid CheckDisk like the plague, however...but maybe that's just me.

    As with all data-recovery, YMMV.

    I just recently had corrupted paritions on my media hardrive, long story short, I lost most of my data. If it really does come to last resort file recovery, highly recommend Testdisk. It recovered an unbelievable amount of my pictures back (if not all), which was what I was after mostly.
