Many quick replies. Much thanks to Paul Fiengo, James Scott, Sammy, Chirs
Barnard, Bob Payne, Michael Horton, Chris Dupre, etc...

The concensus is as long as I don't overlap cylinders, I'll be okay. And
don't forget to label the disk before quitting format.

Thanks again.

Don't laugh now, I've never done this before. I have a big 72GB drive in
my Sun 280R. Can I format->partition slice 7 without affecting the
currently in use partition slices? I need about 30GB on slice 7. So I'll
just start at cylinder 4951-<whatever>. Will that mess up any of the other
slices or destroy data? Thanks in advance.
