I accidentally corrupted my USB drive and want to format it. I’m afraid of losing all the important files stored on it. Is there a way to format the USB without losing data? What steps should I follow?
Whoa there! Formatting a USB drive means wiping everything clean. If you go this route without backing up your data, it’s buh-bye files. Before you do something drastic, let’s figure out how to recover your precious files.
First things first, you can’t format the USB without losing data. Formatting erases everything on the drive, so that’s not the way to rescue your files. Luckily, we have ways to recover corrupted files before you slam that format button.
Here’s what you do:
- Stop using the USB drive immediately to avoid further corruption.
- Download a reliable data recovery software. I’d suggest something like Disk Drill Data Recovery Software. This tool can help recover files from a corrupted or damaged USB drive.
- Install the software on a different drive (not the corrupted USB). Running it from the same USB can overwrite the files you want to recover.
- Run a deep scan on your USB drive using Disk Drill. The software will search for recoverable files.
- Preview and recover your files. Before you save the recovered files, make sure they are intact and not corrupted.
Once your files are safely backed up to another location, then you can proceed with formatting the USB drive.
Note: This whole process can take some time, so make sure you got some snacks and patience!
Other options include reformatting the USB into smaller FAT32 or NTFS volumes, but seriously, just try the recovery first!
Be cautious and prioritize recovery before formatting. Hope you get your data back!

Alrighty, let’s get something straight—formatting a USB means saying adios to your files. So, let’s save those precious files first! Agree completely with @cacadordeestrelas on the fact that you needn’t format if you haven’t tried recovering your files yet.
Here’s another spin on it:
-
Chill for a sec. Don’t do anything else with that USB—no adding, deleting, or moving files around.
-
Use a tool like Recuva or EaseUS Data Recovery Wizard if you’re not feeling Disk Drill (though it’s a solid choice). These are available from well-known sources like Piriform or similar.
-
Get that software up and running on a different drive (C: or D:, just not the corrupted one).
-
Fire up the recovery scan, sit back, and let it work its magic.
One more tip (more like a pro move)—sometimes, if one software doesn’t find your lost files, another might. Don’t be afraid to try multiple data recovery tools.
After you’ve got your files safe and sound, then you can consider formatting the USB. But hey, double-check those recovered files to make sure they’re the ones you need and not some corrupted versions!
P.S. Reformatting won’t fix everything unless you do a file system check after. Keep a USB stick dedicated just for ‘in-progress’ work next time to avoid these panics.
Cheers!
For convenience: Check out Disk Drill, which excels in recovering files from corrupted USB drives.
Don’t fret! While formatting your USB will indeed erase everything, @sognonotturno and @cacadordeestrelas have nailed it when they say recovery is the first step.
Here’s a different strategy for recovering and keeping your files safe:
-
Check with Command Prompt:
Runchkdsk E: /f(replace E: with your USB drive letter) to fix filesystem errors and make your files accessible again without third-party software. -
Disk Drill Pros:
- Comprehensive: Supports numerous file systems and formats.
- Easy Interface: User-friendly and logical.
- Reliable: Generally high success rate for file recovery.
-
Disk Drill Cons:
- Cost: Free version has limitations, full features come at a price.
- Time-consuming: Deep scans can take a while depending on data size and drive condition.
-
Competitors:
- Recuva: Free option, simpler interface but might not be as powerful.
- EaseUS Data Recovery: Comprehensive but more expensive than Recuva.
-
Other Pro Tips:
- File System Check: After recovery, running
sfc /scannowcan help further fix corrupted files.
- File System Check: After recovery, running
-
Backup Next Time:
Use cloud services or a dedicated external hard drive for essential data to avoid similar mess-ups.
Feel safer now? Go ahead and revive those files before hitting the format button!
Hi everyone, I would really appreciate your help. I’m not exactly sure, but I suspect my USB has become corrupted. It’s quite old (over 5 years), and it has had trouble booting in the past. Now, when I plug it into the computer, it says it needs to be formatted.
Honestly, I think it’s way too old to continue using it, but I still want my data back. I have read the thread, but still I’m a little confused about the methods and what they do. I didn’t format my usb yet.
It’s 64 GB Kingston DT SE9 and I’m on Windows 11 Home, if that’s relevant. I mostly have photos there and maybe a few docs.
Is there a way to format USB without losing data? What should I do? Recover first or try chkdsk?
Please, no! Don’t run CHKDSK yet. It can sometimes make things worse by modifying the file system, especially on unstable drives. It’s more of a repair tool than a recovery tool. You should recover data first. There are a couple of tools people suggested here, they would do. Only after you recover what you need should you format it. At that point, you can try a full format to see if it becomes usable again, but honestly, I wouldn’t trust it for anything important anymore.
@Jason Good thing I didn’t rush with fixes… I see a lot of praise here for Disk Drill. Is this tool good? Or should I try something else?
Data recovery tools work quite similarly, so just choose something within your budget. Don’t overthink it.
@Liam While I agree with what @SnailCrash said, I think you should choose a tool that has a backup option. Disk Drill is a reliable tool, and I’ve had no issues using it. You mentioned your USB isn’t stable, so it’s better not to stress it too much. You can create a byte-to-byte backup with Disk Drill and scan it instead of the USB. The process isn’t too complicated, but if you need any help, I’m here.
So, I should create a backup, then recover data? And my usb is safe to format? Got it. But I’m curious what other methods are for?
@Liam CHKDSK is meant to repair the file system so Windows can read the drive again. It works best when the structure is only slightly damaged. The problem is that it modifies the data on the drive, so on an unstable or failing USB it can actually overwrite parts of files you’re trying to recover.
Other tools (like PhotoRec, UFS Explorer etc) do basically the same job as Disk Drill, they scan the drive and try to rebuild files. The reason people suggest trying multiple tools is that each one uses slightly different algorithms, so results can vary.
UPDATE: I went with Disk Drill in the end.
I created a backup first like you suggested, then scanned it. It actually found way more than I expected, around 1,200 files. The previews helped a lot too, since I could quickly check which photos were still intact before recovering them. Most of my important pictures opened fine after recovery, so that’s a huge relief.
Thanks a lot to everyone here for the advice, seriously 
Now I just have one more question. Maybe a little dumb one. I’m about to format my usb. What does the “quick format” option mean??
@Liam Not a dumb question at all, it’s actually important here.
-
A quick format just recreates the file system structure. It basically “resets” the USB so it looks empty, but it doesn’t check the drive for errors or bad sectors. It’s fast, but it doesn’t tell you anything about the actual condition of the USB.
-
A full format, on the other hand, takes longer because it scans the entire drive and checks for bad sectors. If your USB has worn-out memory cells (which is quite possible after 5+ years), this process can reveal that.
In your case (old USB + previous instability), a full format makes more sense. It takes longer, but it can reveal if the drive has deeper issues.
@Jason Okay, I understand, thank you
Don’t keep replugging that drive over and over to see if Windows finally reads it. On a five-year-old stick that’s already flaky, every mount is a chance for it to drop dead completely. @jason is right that chkdsk can make it worse, but the bigger risk here is the hardware itself, not just the file system.
Here’s the piece nobody’s mentioned: before you run any recovery scan, make a raw image of the whole drive first. A failing flash drive can survive one full read pass and then not survive a second. If you image it to a file on your PC, you recover from that copy instead of hammering the dying stick with deep scans. Disk Drill actually has a byte-to-byte backup feature for exactly this, and so does ddrescue if you’re comfortable with something more manual. Either way, the point is the same, get the data off in one pass and work from the copy.
Photos are actually the easy case, so I’d expect decent results. JPEGs have clear signatures, so even a scan on a corrupted file system usually pulls them back cleanly. Docs are a bit more hit or miss. Just check the recovered files open properly before you trust them, since a recovered photo can look fine in a thumbnail and still be half garbage when you open it full size. And yeah, once you’ve got everything, toss the drive. A 64GB Kingston isn’t worth risking your next batch of photos on.
