device I/O Errors hard disk error help


I'm getting a lot of errors in my syslog along the lines of:

I/O error dev 08:22 sector 12345678

Now occasionally, the system has become totally unresponsive, this has gotten progressively more common.
Now its old hardware, PII era and running slackware 9.1
I have 5 disks with various mounts but no raid and I'm wondering how to diagnose which drive is causeing the problem.

I've noticed these errors on 08:22 08:31 so I'm assuming that means its more than one drive which I guess could point to the scsi controller?

Any tips or pointers would be greatly appreciated.

I've also got some links to some images of these errors should they be of any help

/etc/fstab looks like
Code:

All help appreciated.

Have you tried fsck to find out which drives are problematic ? (About checking the scsi controller, I have no clue.)

If you are able to log in as root you can use smartctl to display information about the different drives, including drive conditions.

Try it with
Code:
smartctl -a
to see the complete error status of the disks, sorry should have mentioned that. But seeing the short output I would assume that it is the third disk that is the faulty one.

The above is with the -a switch actually

The third drive above is /home which I run reiserfsck on and it didnt show anything.

I was thinking of temporarily creating new mount points for /var and /home on a new drive and see if that helps, as they are both on their own drives at the moment. Only thing is it can take a few months of this problem to air itself.
