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.

I'd be more supsicious of that well-known rubber bumper...

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 :-)
