[cctalk] Re: Double Density 3.5" Floppy Disks

[Just Kant via cctalk]

I have a vague recollection of someone telling me there was a trick to 
demagnetizing high density disks. Perhaps wave a magnet in various ways, even 
moving the magnet to and from the disk's surface. Then again maybe it's just a 
chatgpt style hallucination. Wouldn't hurt to try though.
