This looks like a simple bad disk drive. Notice that the sectors are
quite close.
If you like you can move the drive to a working machine and run a
badblocks on it.
do 'man badblocks' before you start.
Is it SMART capable? What does
  smartctl -a /dev/hdc
show?

ddrescue may be your friend if you need to recover data.

Reply offlist if this is the case.

Have you got smartd running?
I get a similar problem running some smartcl commands (-s on and -o on)
I suspect this is a libata ata passthru problem - but I'm *guessing* :)

check the last messages in dmesg then run
smartctl -data -s on /dev/sd...
smartctl -data -o on /dev/sd...
See if there are new messages in dmesg
