Bravo!  This is exactly the kind of answer I appreceate!  Thank you Alex.

One minor point...  What has to be done (if anything) to the HD driver
on the ST (or the other utilities for that matter) to get them to
realize there's additional disk space out there?

Also, is it possible to do this with an Atari HD and a Supra and then
which HD driver would one use?  (Not holding my breath on this one, I
mainly curious about just how compatable the Supra and Atari hard
disks are...  I own a Supra and it would be nice if I wanted to expand
if I could buy an Atari HD if I wanted to...)
