da0:ahd1 means its disk zero on the second controller..

Here are your 2 controllers:

Tape drives on the first controller (ahd0):

Disk drives on the second (ahd1).. da0 is the flakey one:

One way to find out exactly which disk is da0 if you can see the disk
activity lights would be to "dd if=/dev/da0 of=/dev/null" ...the disk
with the solid light will be da0..
