I don't know how CDs work. I double checked that there was none in
either of the CD drives.

I guess some pointer artimetic or anything went wrong here for some
reason. ad0 is a simple hdd with a few slices with different, mostly
FreeBSD, installations. ad8 has, as seen above, eli on the disk and
one standard gjournaled UFS on top of that.

Is there any information I could try to find out to find that bug.
I had done the same thing hundreds of times before, the only new thing
from yesterday on was the spindown on 2 of 3 disks.
