Try a "dd if=/dev/hda of=/dev/null bs=16k" and see if the error occurs
again.  If it does again at the same location, you have a hard error on
the disk at that location.. You can work around it with the mkfs -c
option which will map out the bad blocks.

If you get the same sort of error in a different location, you may have
a disk drive that is on the way out.  Take a backup of everything
important ASAP.

smartd might be useful here to monitor the drive. ;)
