A couple of years ago, I made the mistake of transferring my SD card from one camera (a Polaroid point-and-shoot that had low battery charge at the time) to another (an AGFA Photo point-and-shoot). I had no idea the files would be damaged, so I learned the hard way not to share SD cards between different cameras. :(
At one point, I was still able to review photos on the computer, but now the jpegs seem completely unreadable. I am still able to open the SD card on my computer, but the files yield the same error message that I am unable to view the image.
I've tried Zero Assumption Recovery. It was able to retrieve a few files, but from a different session.
Is there any other way for me to get my photos back?
