Hi David. I have a suggestion for you; don't follow those instructions "to the letter", they're really just a guideline. What you want to do is see if there are any new SCI disks added to your ssytem after installing (or plugging in?) the Zip drive, and *that* will be the device you want to use (instead of "sda4"). use the following commands to find the device: 'dmesg | grep -e sd' (drop the quotes, of course). Once you see a reference to a zip drive in that output, than use the following (as root, use "su -l"): fdisk -l /dev/<zip-disk-device>. I hope you get it to work! -David Chipman
