Can you define corrupt?  If you copy your folder to the server, then copy back from the server to the workstation, do you still have problems with those files?  Does the file size change? (are they receiving more or fewer bytes?),, did you try to compare MD5 Sums?

If the files really are becomming corrupt somehow, did you check Dmesg on your server to make sure you aren't having serious hardware problems on that end?
