I accidentally formatted my ExFAT USB drive and need help with data recovery. I haven’t copied anything new to it, but it had important files I need back. What are the safest steps or tools to recover data from a formatted ExFAT USB drive?
I ran into this after formatting a 128 GB camera SD card by accident. It was exFAT, and at first I figured the whole weekend of photos and videos was gone. The main thing I learned is pretty simple: stop touching the card right away. That matters more than the specific recovery app you pick.
Don’t put anything new on the SD card or USB drive. Don’t format it again. Don’t run CHKDSK or other “repair” tools first. If the old data hasn’t been overwritten yet, every write to that device makes recovery less likely.
I checked backups first, but didn’t have one that helped, so I went with recovery software. I used Disk Drill, and it brought back almost everything in my case.
The process was basically:
- Install Disk Drill on the computer, not on the SD card or USB drive you’re recovering from.
- Plug the exFAT card in through a card reader.
- Select the card in Disk Drill and run a scan. Universal Scan is usually the one to start with.
- Let the scan finish, then preview the files before recovering them.
- Save the recovered files to a different drive, like your internal SSD, not back to the same card.
One useful detail: the Windows version lets you recover up to 100 MB for free. That’s enough to confirm whether the files are actually recoverable before you decide if the paid version is worth it.
If the card or USB drive is acting flaky, there’s one extra step I’d take first. Disk Drill can create a disk image, and that’s worth doing if the device disconnects, reads painfully slowly, or seems inconsistent. Scan the image instead of hammering the original media over and over. It’s safer for a drive or card that might be failing.
For deleted camera videos, especially from drones, DSLRs, mirrorless cameras, GoPros, or dashcams, check Advanced Camera Recovery (ACR) too. I didn’t really need it because my recovery was mostly photos, but it’s often suggested for fragmented MP4, MOV, and similar video files that normal scans may not piece together properly.
If Disk Drill doesn’t turn up what you need, TestDisk is another option. It’s free, but it’s much less beginner-friendly and is usually better for damaged partitions than for picking out individual deleted files.
The one case where I wouldn’t keep trying DIY tools is physical failure. If the SD card or USB stick isn’t detected on any computer, keeps dropping out, gets unusually hot, or has visible damage, stop. More attempts can make things worse. A recovery lab is expensive, often a few hundred dollars or more depending on the problem, but if the hardware itself is failing, that’s usually the better route. Many labs will at least evaluate it for free.
If this is just deleted files or an accidental format, stop using the device now and recover the data before doing any repairs. That’s what saved me.

Whether it was a quick format or a full format matters a lot here. If it was the normal quick format Windows does by default, recovery is very possible because the file contents may still be sitting there. If it was a full format, or the drive was formatted on something that zeroed the whole device, the odds drop hard.
I agree with the “stop using it” advice, but I’d be more cautious about expectations. After an exFAT format, you might get the actual files back but lose folder structure, original names, dates, or partial videos. That does not mean the scan failed. It means the file system records were damaged or replaced, and the recovery tool is finding files by signatures instead of reading the old directory tree.
If the files matter, make an image of the USB first and scan that instead of the stick. Then try a tool like Disk Drill, R-Studio, DMDE, PhotoRec, etc., and recover to your computer or another external drive. Do not recover back onto the same USB. If the first scan shows the files with correct names and previews, great. If it only shows “file0001.jpg” type results, recover the important stuff anyway and sort it later. The annoying part is that the safest method is slower, but it avoids turning a recoverable mistake into a permanent overwrite.
Quick format does not automatically mean you’ll get the old folders and filenames back. On exFAT, the format can replace enough file system metadata that a recovery program may only find raw files by type. That is still a recovery, but it can look messy, especially with lots of small documents or files that all have generic names afterward.
Before scanning, I’d flip the USB drive to read-only if you can. Some USB sticks have a physical switch, most don’t, but you can at least avoid opening it in Explorer more than necessary and ignore any Windows prompt asking to “fix” or format it. If you know how to use imaging tools, make a sector-by-sector image first. If not, the next safest practical move is to scan it once and save recovered files somewhere else. Do not “test” recovery by restoring a few files back onto the same stick.
Disk Drill, R-Studio, DMDE, and PhotoRec are all reasonable choices, but they are not magic. Preview matters more than the brand name. If a tool shows previews of your actual photos/docs, that’s a good sign. If it shows thousands of unnamed files, recover only the types you care about first so you don’t waste hours sorting junk. Disk Drill is easier for non-technical users, and this Disk Drill walkthrough may help if you’ve never used this kind of software, but don’t keep installing and trying random tools directly on the USB. Install everything on your PC and treat the USB like evidence you’re trying not to disturb.
The file types matter here: photos and plain videos often come back better than scattered project folders, databases, or lots of tiny Office files after an exFAT format.
If the files are worth money, make an image first; if they’re just personally important, scan once with Disk Drill or similar and judge by previews, not by the number of “found files.” A huge list of recovered junk can look encouraging, but previews are the real test.
