Connecting a big disk (CDC Wren VI) to a little Sun (3

[Dennis Gentry]

I am trying (so far unsuccessfully) to format and install a CDC Wren VI to
my Sun 3/60.  Has anyone done this?  I can get the Sun to talk to the Wren
(and even format it for, say, 5Mb).  My main problem at this stage is
computing the number of sectors per cylinder and such.  The Wren
apparently has a variable number of sectors per cylinder from the inside
cylinders to the outside, and the Sun formatting software doesn't know
anything about that.  (In fact, it wants me to have an Emulex or Adaptec
controller, which I shouldn't need since the Wren has a built in SCSI
controller).

Anyone ever done this before?

Thanks,
