I suggest you turn on AWRE and ARRE and then run a dd command to attempt to remap the block automagically: scsi -f /dev/rsd0 -m 1 -P 3 -e # Make the above changes with your editor, save and exit # Now scan the disk, hopefully it will be able to do retries and # recover the bad block... dd if=/dev/rsd0 of=/dev/null bs=32768 Your drive life will probably go up by an order of magnitude... > If that helps at all. Anyway, my friend Chris (hi, cause I know you're > reading this too) has Micropolis 4.3s in his machines and has no > problems, so I'll switch to those.
