Was there important files on it? If not, I would load up GParted and wipe it clean, do a fresh partition.
Also, if you can, I'd go with NTFS instead.
Assuming there are files that you wanted on it, that is quite the problem. If you aren't seeing anything even after unhiding hidden files, does not make sense. Could be a damaged thumb drive, but I have never heard of them doing that before.
