Rocks to crush the zip disks, paper to write why you might do this, and scissors to cut up the media.
Enjoy!

I have a similar issue. I've got a few Zip Disks that I've been trying to get data off of, but cannot. I've got an internal IDE Zip Drive and using an IDE-to-USB connector to a Windows 7 laptop. Unfortunately, Windows is not finding it, or the drivers. Thought about going to a desktop with XP or using XP Virtual mode, but only as a last resort.
Sidenote: Tried Ubuntu also, but it wouldn't mount the drive either.
Anyone got any suggestions?
