You obviously weren't involved with disk drive qualification!

This wasn't true with either ESDI or ST506 drives.  It isn't true
with SMD.  It isn't true with IPI.  It isn't true with XXX, where
XXX is any type of disk interface you care to name.  Sure, in any
given category a lot of drives will work, at least most of the time,
but you certainly aren't going to find all of them working all of the
time, or anything even close to it.

Actually, current SCSI drives are *mostly* pretty good on this, at least
as good as in any of the other drive categories I have ever been involved
with at the disk qualification level, and probably better than some.

IDE I can't comment on, as I've never messed with it.
