Geez.

I'd agree with what ubuntu at rio.vg wrote: Try to make a backup of
the data and dump the drive.

Maybe you could also try to "reformat" the partition with a new
filesystem.

Another check: Do 

        dd if=/dev/hdc of=/dev/null

This will read all of /dev/hdc and dump it in /dev/null. If there
are hardware problems, the read will fail somewhere.
