Thanks Vassilis, Tony, Joe, and Mike. I've since figured out that the
top head is damaged (it's still there but its mounting has been
stressed so it doesn't sit quite right). Oh well, it's not all bad, I
have other working units for use and I guess I now have a known-bad
drive to on which to practice repair techniques, now all I need is time!

There are at least 2 types. The older one is full height and has a 26 pin
connector, with a separate 4 pin power connector. height and has a 34 pin connecotr (with power on some
of the odd-numbered
pins). The former is used in the 9114A, the latter in the 9114B, for
example.
I have. I'm pretty sure that it was on a drive that used a Seagate drive
internally (251 I THINK!) but I don't remember what HP model it was. Sorry.
I've tried it with some other drives that used non-Seagate drives but could
never make it work. I wonder if you had a working and replacement drive if
it would be possible to install both bare drives in another computer and
use some kind of cloning software to "format" the replacement drive.
Someone that knows HP-IB drive operation may be able to write a program to
make the drives format themselves (assuming that they're even capable of
it). Steve Robertson is doing a lot of work in that area.

or similar combination hard/floppy drive that has

and take the floppy drive from it.
IIRC, the 9153 uses the later drive (the 9133 uses the older one, as do
many other disk units).
The older HP hard disk units used standard hard disks too (the 9133H uses
an ST225 IIRC). However, they seem to have been specially low-level
formatted, and I've never found a way to format a non-HP drive to work in
thuse boxes. Has anyone ever done this?
