And yet, I have a cheap Radio Shack tape degauzer and it erases 3.5" disks just fine. I do it all the time whenever I have one that refuses to reformat. Quick pass over the degauzer and they usually work fine. If not, time to toss them. As for 720K disks I bought a box of new ones (12 boxes actually) several years ago on eBay and expect they will out last me. Especially now that I am moving everything to Goteks. bill
