It might be that your FAT is bad.
on fat (16) and fat32 there are two file tables for each partition, whebever there is a mismatch between the two Tables - you cant tell which of the copies is good.
I strongly believe that if Backup the file, format the effected partition than everyhting will be alright.

Cheers.
