Jeff,
I'm not familiar with Next so this is speaking from general unix experience,
but I think you need to copy the "whole disk" parition rather then the "a"
partition on the OD. Assuming NextStep is using a BSD-style disk lable, which
it looks like it is, "dd if=/dev/od0c of=/dev/od1c" would do it. I use this
technique all the time on my linux machine to make archive copies of OS disks
and it works great; the linux example would be "dd if=/dev/hdc of=<file>", and
then <file> can be burned back to a CD later...
