Filesystem may have the corrupted free-cluster value. I couldn't reproduce the problem on 2.6.12-rc4. Could you try a recently dosfsck (dosfstools-2.11 or later)? Also could you send the output of above program?
"dosfsck" did find a problem in the free-cluster value. And also said the backups FAT was different than the original FAT.
I didn't use "dosfsck" to fix the problems though (not that it couldn't, I just didn't try). As I had already copied everything to another disk, I just used "mkdosfs" to reformat the drive, and it works just fine now.
I still don't know what caused this, probably something related to some "kernel panics" I was seeing on shutdown (in a Fedora 3 installation, not Debian), after doing an umount+unplug.
I didn't though of using "dosfsck" because Windows' checkdisk was saying the filesystem was perfectly fine... It makes me feel really safe trusting MS tools... not.
