:        I have a Segate ST-412 10meg drive hooked up to an A2090 card.
:        As this type of drive wasn't on the PREP list of drives I used
:        ST-442 (which is an ST-506 20meg type of drive (i think)).
:        When I formatted DH0: I noticed that I had 323 cylinders (format
:        died with a 'Can't fine device' type of error).  I've since defined
:        the drive as a 4 head generic 10meg drive and it works fine with
:        305 cylinders.
:
:        Since 10 meg = 305 cylinders, how can I make use of the other 18
:        cylinders?

	Usually, extra cylinders exist on the inside or outside of the 
disk to give a landing area when you power the drive down (most new drives
do not actually land on the disk surface, but this is a 'safety' or 'lock'
zone) *NEVER* use more cylinders than the drive specs show.  Look at the
description for your particular drive and don't use more cylinders than it
says you can use.

	10 meg ?  Boy, that is small!  Get a bigger drive!
