According to my know it all LInux book:
"Because they just standard (but removeable) SCSI or IDE disks most aspects of
their use are similar to those for other block devices."
In other words:
Find out which disk represents your zip drive. hda, hdb, hdc, or hdd.
Then edit your fstab with the following line:
/dev/hdc4 /mnt/zip auto user,noauto,rw 0 0
Of couse, replace your /dev/hdc4 with the block device that represents your zip
drive. Then make sure that you create the directory /mnt/zip.
Remember that Iomega uses primary partition number 4. They just do, nobody
knows why. This is what you get if you format a Zip disk under Windows. If
you want to make a zip disk work under Linux, you have to use fdisk and then
mkfs to make the file system.
All done!
