This is nearly the same as I had. For more confusion, there is even
an entry in the SunOS /etc/format.dat for the IMPRIMIS drive:

disk_type = "CDC Wren VII 94601-12G" \
	: ctlr = SCSI : fmt_time = 4 \
	: cache = 0x11 : trks_zone = 15 : asect = 5 : atrks = 30 \
	: ncyl =  1703 : acyl = 2 : pcyl = 1931 : nhead = 15 : nsect = 80 \
	: rpm = 3597 : bpt = 41301

The nsect=80 does not match what the drive and the spec says: They
talk about 70 sectors...

Maybe I take my old SUN drive as root FS and the other one as /usr :-)

So do I.
