I put the disk back in the original system to make sure I hadn't damaged it.
The volume header had been destroyed by the 4/470, but I reformatted the disk,
recreated the filesystem on it and it was fine.

I received some helpful jumper info from (Ralph Merwin).
That helped me confirm that I wasn't doing anything wrong. I finally
called Maxtor. The tech support folks I spoke with were very helpful.
They explained that not all SCSI implemetations will work on Sun boxes.
Apparently Sun altered the SCSI command protocol ever so slightly to suit
their needs. Most manufacturers offer prom upgrades to solve the problem. This
particular disk is several years old and has an old firmware revision. I
have ordered the upgrade for this drive and I will try again.
