I was using a 64gb Uniserb USB3.0 thumbdrive for storing my RAW canon images (.cr2) while travelling in Tokyo. everything worked perfectly fine during the trip, as I transferred the images from sd card to usb drive.
when i came home, it popped up the dreaded message:
"do you want to format the drive in H: before you use it?"
since it cannot be accessed in windows explorer, i tried using testdisk to recover the files.
See attached log for more info - there are a couple of scenarios happening.
1. Testdisk would say 'Bad relative sector' and not be able to detect the partition
2. Testdisk would detect the partition, but upon doing 'Deeper Search' - the drive disconnects by itself, leading to read errors.




I also tried using PhotoRec to recover my 2,500++ images, but it ALWAYS stops at 41 images before the drive disconnects by itself and becomes undetectable in disk management. another bad part about PhotoRec is that my filenames and metadata are stripped away in the process, so i'd prefer not to do that.
as a last resort, of course, i'd rather get back all my files first, then decide what to do with it later on.
please help me! i'm really at a loss now.
