Just for the sake of it, in case anyone wondered, after putting in
many hours of reading documentation and playing with the disk, I gave
up on a Seagate 9GB Cheetah, stubbornly presening itself as a 9GB
Barracuda, and would not let get itself formatted to anything but
1GB capacity.
More precisely, I was able to reformat and analyze, but not label
the disk with any tools available under Solaris. I suspect a burnt
transistor or a trace caused hardware parameters of the disk
to appear different from what they should have been.
In my efforts to learn something and make use of the disk I received
significant help from Casper Dik and Peter Stokes. Other people also
offered advice: Robert Reynolds, Mark McManus, and Juergen Waiblinger.
