You *may* need to use a partition number. For instance, all DOS/Windows Zip disks use partition #4. So, to mount a Zip disk in Linux, one must mount:

/dev/hd?4 (where the ? corresponds to the Zip drive IDE channel. A SCSI Zip drive would be a 'sd' device.)

I can't explain it any better than any existing HOWTO. It's just the way it is.

Could the LS120 follow the same paradigm? Have you tried just mounting a floppy (versus a SuperDisk)?
