[plug] hard drive errors

[Barry]

i have been getting the following hdd errors in syslog and was wondering if i
am having a drive fail on me.
listening to the machine it sounds like it is thrashing but there is plenty of
spare memory and swap

Feb  9 11:03:45 chronos kernel: end_request: I/O error, dev 03:06 (hda), sector 1230199 

is there any way to fix this?
