Going by experience, I'd say 'short read' sounds a little ominous -- and
the first thing you should do is update your backups -- but if you want
to give the disk a chance, you might consider taking the machine
offline, copying the filesystems elsewhere for safekeeping, and running
'badblocks -wv' on the device, (e.g., 'badblocks -wv /dev/hdb').
If you have a little more time, try the manufacturer HD utilities. Some
of the manufacturers include pseudo-low-level formatting routines, that
can in some cases do wonders for an aging ATA disk.
