LAST EDITED ON Nov-24-00 AT 05:35 PM (GMT)I don't know about 5 years, but I have some zips that are ok and were made more than 2 years ago. I would guess that they will still be ok for three more years as I have floppy disks that were made 10 or more years ago that are still OK. Of course, the slightest magnetic field can wipe them out.
