I accidentally formatted my SD card and realized afterward that it had important photos and videos I have not backed up anywhere else. I stopped using the card right away because I do not want to overwrite the deleted data. I need advice on the safest way to recover files from a formatted SD card without causing more data loss.
I ran into this with a camera SD card once, and the short version is yes, your files are often still there.
What usually happens after a format on a camera, drone, or PC is a quick format. The card does not get wiped in full. The device mostly resets the index and marks the space as available. Your photos and video clips often stay on the card until new data lands on top of them.
First thing I’d do, stop using the card now. Take it out. Do not record more footage. Do not copy random files onto it. The more you write to it, the higher the chance your old files get overwritten, and then recovery gets ugly fast.
If you want the best shot at getting things back, use recovery software. I’ve had the best luck with Disk Drill. The part I liked was its video recovery handling. Big video files from drones and cameras tend to be split into chunks across the card, so some tools find the file names but give you clips that won’t open. Disk Drill has an 'Advanced Camera Recovery' mode meant for piecing those files back together.
What I’d do, step by step:
- Connect the SD card to your computer with a decent card reader.
- Install Disk Drill on your computer’s internal drive. Do not install anything onto the SD card.
- Launch it, pick the formatted SD card, and start a scan. If this was drone or camera footage, use Advanced Camera Recovery.
- Wait for the scan to finish. Preview what it finds so you can check whether the files open cleanly.
- Recover the files you need to a folder on your computer. Do not save recovered files back to the SD card. If you do, you risk overwriting the same data you’re trying to pull off.
If you want other options, PhotoRec is legit and free. I used it years ago. It works, but it feels rough. No normal GUI, lots of command-line style screens, and you usually lose original names and folder layout. Sorting recovered stuff later is a pain. R-Studio is another option, though it felt more aimed at people who do this stuff all week. Also, its free limit on file size makes it a poor fit for video recovery.
If the card has stuff you cannot replace, or your computer will not detect the card at all even after trying another reader, I’d stop there and look at a recovery lab. Those places use hardware tools and chip-level methods regular software does not. It costs more, yeah, but many of them work on a no data, no charge basis.

Stop using the card. You did the right thing there.
One thing I’d add to what @mikeappsreviewer said, make a byte-for-byte image of the SD card first, before you run recovery. I prefer this step on flaky cards because every extra read stresses cheap flash media a bit more. If the card starts dropping out mid-scan, you still have the image file and you work from that instead of the original.
Best flow:
- Put the SD card in a reader with the write-protect switch on, if your adapter has one.
- Use a disk imaging tool to clone the full card to your PC.
- Run recovery software against the image, not the SD card.
- Save recovered photos and videos to a different drive.
I slightly disagree with scanning the card first if it holds stuff you care about a lot. Imaging first is safer.
If the format was quick format, recovery odds are often decent. Full format is worse, but exFAT and FAT32 cards still sometimes yield partial recovery, esp for JPG and MP4. File names and folders are often gone, so sort by file type and date afterward.
Disk Drill is a solid pick for this, and it handles formatted SD card recovery well. Recuva is fine for simple photo pulls, but it tends to miss fragmented video. If your card shows the wrong size, asks to be formatted again, or disconnects, skip software and go to a lab.

I’d do one thing a bit differently than @mikeappsreviewer and @himmelsjager: check the card’s health before hammering it with a long deep scan.
If the SD card still mounts normally and shows the correct capacity, that’s a decent sign. If it’s suddenly tiny, read-only, disappears mid-copy, or asks to be formatted again, don’t keep poking at it. That can mean controller or flash trouble, not just a simple format mistake. In that case, every extra attempt is a gamble.
For a normal accidental format, the safest practical path is:
- Lock the card if your adapter has the switch.
- Plug it into a reliable USB card reader, not the camera/phone.
- Copy a full image of the card if possible.
- Recover from the image to your computer or another drive.
Where I slightly disagree with the “just use any free tool first” mindset: free tools are fine for JPGs, but they can get messy with large MP4/MOV files and fragmented clips. That’s where Disk Drill tends to be worth trying because it handles formatted SD card recovery pretty well and gives you previews before restoring. Preview matters a lot. If a recovered video won’t preview, don’t assume the final export will magically be fixed.
Also, after recovery, verify files before doing anything with the card. Open a bunch of photos. Scrub through the videos, not just the first 3 seconds. Corruption often shows up later in the file.
If you want a visual walkthrough, this Disk Drill review and SD card recovery walkthrough is pretty easy to follow.
One more thing people skip: once you recover what you can, retire that card if it has acted weird at all. SD cards are cheap, re-doing lost footage is not. Thats the painful part most of us learn once lol.
