This would depend on the PC controller being able to handle the low-level
format of the HP controller, which is by no means certain!.

I've never heard of 'Ghost'. Can it even handle drives with non-standard
numbers of sectors per track?

Incidentally, I do know that the HP drive boxes are very fussy about the
drives they'll support. During the self-test they try to select heads
beyond the number of heads that should exist, and give an error if the
drive doesn't complain.

There is a set of 4 links called the 'Ident Sea' on the controller board
in my 9133 that seem to select one of 16 possibel drive geometries. I
have no idea what they are, though.
