There are three formats for floppies that the NeXT supports: NeXT unix,
MSDOS and raw.

NeXT's unix format is really nice in that the floppy is a unix removable
medium and works as expected (and quickly). Unfortunately, I haven't
had any luck mounting them on a Sun or in getting a Sun to make a unix
formatted floppy.

MSDOS works but is (painfully) slow on both sides. In addition, you are
limited to DOS's eight.three character names.

Raw floppies are what I use. For example, if I want to move a set of
files from the Sun to the NeXT, I do:
	<insert floppy in Sun drive>
	$ tar -cf /dev/fd0 <files I want>        ;cpio works too
	$ eject

	<move to NeXT - DON'T insert floppy yet>
	$ tar -xvf /dev/sd1h
	<When popup appears requesting floppy, insert it>
	$ /usr/etc/disk -e /dev/rsd1a
A couple of notes: The sd1 is the drive on MY system, replace it with your
number. Some of the above on the NeXT requires you to be root or to change
your file access flags. Lastly, more work is needed on your end if the files
won't fit on a single floppy.
