Why do you need that particular drive? If it's for your PERQ, then any
ST412-interfaced drive will work. The Vertex V150 was commonly used in US
PERQs, I'ev heard of Maxtor XT1140s working, and so on.

How do you know, what have you tried to do? The PERQ low-level format is
strange (to the extend to havin user data words -- actually filesystem
pointes for POS -- in the sector headers) But any drive should go ready,
and that would be enough for you to get the machine to boot from floppy
if everything else is working. (It would be ridiculous to have to have a
working, formatted, hard disk to boot from floppy, how would you ever
load the formatter?)
I'll assume you set the drive select links correctly :-)
