I picked up a couple of 4Gb Seagate SCSI drives recently (used but
"supposedly" pulled from a working system-- I know to take this with a
grain of salt, but "what the hey"). They are recognized on "boot -r" (
device files are created) but are reported as being "unformated"

Running format I define the type as (based on a "loose" description I
found on another group posting)

Specify disk type (enter its number): 16
Enter number of data cylinders: 3880
Enter number of alternate cylinders[2]:
Enter number of physical cylinders[3882]:
Enter number of heads: 16
Enter physical number of heads[default]:
Enter number of data sectors/track: 135
Enter number of physical sectors/track[default]:
Enter rpm of drive[3600]: 5400

Retry of formatting operation without any of the standard
mode selects and ignoring disk's Grown Defects list. The
disk may be able to be reformatted this way if an earlier
formatting operation was interrupted by a power failure or
SCSI bus reset. The Grown Defects list will be recreated
by format verification and surface analysis.

Thought or suggestions? Hopeless?

The operating system does not recognise the hard-disk eventhough the
BIOS leve does

1) what solaris version ?

2) If hard-disk not listed in sun engineering hand-book , then most
likely not supported by
solaris

3) Does the hdd have any s/ware driver that can be install on the
solaris?

4) Is it worth-while to use the old hdd to store the precious data?

Solaris 7 5/99 ( I would like to go up to a newer version, but I am
trying to mimic a system here that is at a remote location and I have
no control over what version they are running).

The drives are Sun (labelled and everything) 4G Ultra-wides so it is
compatible. I have it in a 711 Multipack. The boot eprom seesm them
correctly, so controller etc are working.

As for #4- it all comes down to $$$$. I could get a "new old stock" one
from a Sun authorized dealer, and pay as much for it as for a 500Gb
drive on my Mac. Besides, I am basically trying to get enough drives
set up ( capacity is not an issue) to try out Veritas here and learn
the ins and outs w/out risking anything on the remote system.
