2. Tried to copy some photo files from external HDD to Flash Drive = FAIL.
Files were OK at 1st, then file names changed to strange characters.
Was I trying to copy too much content to the destination partition?
3. Using GParted...
Tried to re-format = FAILED.
Tried to re-partition = FAILED.
UNKNOWN File System!
4. Installed and ran TestDisk on the problem Flash Drive.
Ran OK.
I have made a testdisk.log file, so that's available if wanted.
Don't know how to get TestDisk to fix this problem.
5. Any advice or instructions?
