[rescue] a different hard drive problem - please help

[Arthur Wouk]

i purchased a 73gig sca hard drive in a sun 611 case some time ago,
and tried to attach it to a 'new' ultra-1. it was not recognized, no
matter what i tried. 

i tried attaching it to various other sparcstations via a 50to68pin cable, 
still in the 611 box, and nothing would work. i had the seller replace
it with a drive which looks brand new. still no go.

then i eventually took the drive, attached a 50pin to
sca adapter, and put it on a sparc2 which is very reliable, and besides
has sformat working on it. it was attached at scsi station 0.
[format sees the drive but gives no useful error messages.]

this time the machine recognizes the drive, and here are the results:

can anyone make sense out of this? is this drive dead? is it
salvagable, and if so, how?

by the way, the ibm DCAS-09F is a lovely drive - i bought two of them
brand new. all i had to do was use sformat to convert them from 520 to
512 size sectors. it is a 1" high drive. however i can only find 50pin
versions of it.
