Hello Brian,

Last time I did this was on a Zip disk, on a NetBSD/i386
machine.  I used NetBSD's fdisk to create a BIOS-level
partition that covered all of the disk except for the first
track.  Then I used newfs_msdos to create a filesystem on
that partition.  Although I wasn't able to mount the disk on
my Sun workstation (perhaps because of endian issues?), it
does work on MS-Windows machines.

I hope that this helps.
