Write protect your zip disks before doing anything to them if you haven't done this several times before (and it doesn't hurt even then).

I'd second that. Definitely create image files of the disks (if possible) rather than risk writing to them accidentally or on purpose. (Though since Zip disks don't have a hardware write protect tab, write-protecting them does involve writing to the disk!)
For creating disk images, a good solution is to use Helix, a bootable Linux CD designed for forensics use. It's guaranteed not to write to the disk. You can get that from

There are utilities for reading disks with bad sectors. I think sg_dd is one, it's probably on the Helix CD. Most normal "dd" programs abort as soon as a bad sector is encountered, so they are not suitable if there are any bad/unreadable sectors on the disk.
I've had good results recovering data from Zip disks using the Helix CD and sg_dd. It can even sometimes partly recover bad/unreadable sectors (it uses the SCSI READ LONG command).
