Sorry for the delay in replying. orville weyrich said: > (1) make sure that the BIOS settings are the same for > both drives.

However, I have gotten that error many times in the past and was under the impression that it was a fairly normal thing and should be ignored. > (5) have you tried using disklable -e to directly edit > the labels to copy the "good" label to the "bad" > drive? Yes, I tried editing both labels, and it wouldn't take for either.

Well, these disks are just extra storage under /var, and ad0 and ad1 are the bootable disks in this system. So I guess I don't have anything to worry about. Again, thanks for your help :)
