Hello
I got someone to give me a flash drive with jpg images on it. Some of the images are degraded or impossible to open.
But others open properly.
Do you have any software that I can use to recover the images?

thank you for your feedback

Are the JPEG files corrupt (bad data) or does the flash drive have bad sectors? Are you able to copy the bad JPEGs to another drive?

try a program called "Recuva"

if the drive is okay and it is just the file system, this one probably is as good as any.

Actually, Recuva may not be the tool you want to use in such a case ..

I had cases like this more than once (see attached image), Recuva recovered the same corrupt files. So I was asked to repair the photos. Files were recoverable though https://youtu.be/Y8bLwSZDHD0?t=298

Another example, Recuva recovered corrupt RAW photos. User was given advise to format the card (don't ask why), result even less files recovered. Now root of the problem was corrupt RAW files to start with. So now files unrecoverable both using file system based software + RAW scan! https://youtu.be/QJIl-oEmjBs

If you need to recover JPGs from usb flash drive with swept out filesystem (or very corrupted filesystem), the best tool is DiskTuna JPEG Recovery LAB.
The 2nd best tool is Photorec with Bruteforce ON, and is totally free.
GetDataBack is the 3th best software for jpg recovering in raw mode.
This tools can rebuild fragmented jpg files via metadata analizing.

In the past i did a lot of experiments, i did try also CnW Recovery 5.21, it was good too but not as much the above.
R-Studio is not good for jpg raw recovery, also ReclaiMe is better than R-Studio.

I did a lot of experiments, i had pretty good result on jpg recovery with GetDataBack 5.50 (using level 4).
R-Studio was far from it, many jpg result corrupted with r-studio. In my opinion that is because GetDataBack can handle pretty well fragmented files with level 4 option.

Thank you for the info. I too believe the only way to determine how well a tool does in specific circumstances is testing.

I never had much luck with PhotoRec brute forcing. Of course it's hard to tell if all fragments that once made up a file did all survive in the first place.

I ran GDB against the disk image of memory card I used in the video, unfortunately it didn't recover a lot, basically same corrupted files as I started with. This was a level 4 scan. Since the file system was really hosed, the test may not be very representative as GDB is a file system oriented tool.
