So, did you add a new drive or no?  I'm confused that you say that no
hardware has changed, but you're putting in a new drive.

My advice is to check for SCSI ID conflicts, termination, etc.  Then, fdisk
it on a NetBSD machine, and try to set it up from that point.  The
disklabel may be different.  Possibly, the fact that the fs on NetBSD is
64-bit may cause a problem.  (random guess)
