Ok:

Now I've really done it.  I went ahead and got one of those zippy HUGE
EESDI drives that cost hardly anything from CDC.  I intend to put it in
my RT Workstation running ACIS.  The drive I bought is a WREN VI with the 
EESDI controller.  Pertinent specs I have are:

		# of Sectors Per Track: 53
		# of heads		15
		# of cylinders		1632

This is a 676 Meg. drive.  Anyway, naturally I can't seem to format the
thing.  I first tried with the ACIS Standalone format program.  That
generates a series of ugly messages about HD ERROR and doesn't even try.
The next step was to try booting the IBM hardware diags.  They don't come
up at all.  Finally I pulled an AIX startup disk (yuck! phew!) and inserted
it.  We got to a step where we were going to format the disk.  The program
asked me for the information listed above and then proceeded to dy with a
similar HD ERROR.  I tried a variety of combinations of values.  All to
no avail.  The question is:

	1) Has anyone used this disk in an RT under EITHER AIX or ACIS?
	(the drive is CDC part number 94196-766)

	2) Does anyone have any generic advice for me?
