Question: How can I get my zip drive working after RH6.2 installation?
Possible Solutions:
        1)      RH7.1 should work.
        2)      First off, it can be helpful on older Zip drives and computers to have a Zip disk in the drive during boot up to ensure proper detection. After booting, login as root . Next, create a mount point for the drive by typing: mkdir /mnt/zip. Determine the device name by typing this command: dmesg less . Look through the output for the "Detected Removable IDE/ATAPI disk hdx at..." label near the zip entry (x is the Zip drive letter like hda or hdb). Mount the Zip drive on the mount point by typing: mount /dev/hdx /mnt/zip . At this point you may copy files to and from the Zip drive as usual. To switch disks simply unmount the Zip drive by typing: umount /mnt/zip Put in another disk and mount the drive as you did before.
