I always wondered what the differences were that wouldn't let a drive set up
on one card be used with another.
While it may have been possible to, say, employ FM
recording
on a ST412, I've never seen it done in practice. There *were* some
RLL variants that attempted to push things past 2,7 (Perstor?) on a
412 interface, but they were never very reliable or popular.
I ran a perstor card with a pair of ST251 drives up until I got my first 540M
ATA drive, 24/7, for a few years, and they proved quite reliable. The
bearing noise of those drives got to be a bit much by the time I shut them
down, though.
