That's actually a good thing.
If the disk is wiped to the point that it needs a format from the OS,
then I can toss the disks in a general use box, and not worry about which
OS they are used on (Mac or DOS/Windows). This way, they can be formatted
fresh for the given platform they are needed on (yes yes, the mac can
read PC disks just fine, but I prefer not to do that for Mac specific
uses)

Ok, I guess I have to black track the stack of VHS tapes I have then. No
biggie, I was just hoping to avoid running them thru a VCR for 2 hours.

Ok, not exactly the way I had been using it. I was just putting it on top
of the item, turning it on, rubbing it back and forth a bit, then turning
it off and removing. I'll change my ways.

Good to know as a "fact" although I had suspected something like this
anyway, so I wouldn't have done it. I also wouldn't have tried it on Zip
disks, or Syquest carts or other removable "non floppy" media for fear of
the same problem. I suspect it might be ok on Zip disks, but I know those
are treated more like a hard drive platter than a floppy disk, so I don't
consider it worth the risk.

I prefer to take them apart and make wind chimes from the platters.
