Kinda sounds like a Quantum Q2020. I had one with a sasi board mounted on
it back in 93'. Has a smoked plastic mech cover and a whole bunch of
warning stickers indicating it can remove digits if you dink with it while
open? I used a CSS Black Box for an interface. Sasi drives (and most scsi
bridge controllers) require specific formatting code. Also, iirc, sasi
devices required a dos-level bad sector map of the drive. In other words,
the dos you use scans the drive and creates a file occupying all the bad
sectors detected. The hardware didn't do that as with most (all?) scsi
drives/bridge controllers.
As I recall, the q2020 has the same geometry as the Seagate st225
(620/4/17).??
The q2020 is an 8" 20mb unformatted drive which yields 16mb (more or less)
when formatted and has a 40ms average seek time.
Mine had an aluminum cased ps bolted to it and the drive stood on it's
side.

This is being asked out of curiosity, since I happened
to
think about it today. About 13 years ago, a large hard disk was pulled
out of a piece of medical equipment and made it's way across my desk.
The drive was made by Shugart and I believe it had a SASI interface. It
was easily as big as a dual-8" floppy enclosure, maybe 14" in diameter
and had it's own PSU. The case over the platters was clear plastic.
One of the guys I worked with pulled the PSU parts out of it and
unfortunately I didn't think to keep the rest of it from being junked,
mainly due to it's size. Any ideas as to what this might have been? It
certainly wasn't near new at the time of it's removal. At the time, we
were still running a CP/M system for our tracking database and we backed
up it's hard disk once a week on it's 8" floppy drive, which was
integrated in the system and standing on it's side.
