I've still got an external USB floppy disk drive, so could use the disks in any PC with a spare USB port. I have shredded a large number of disks, rather than throw them whole in the bin, and had to break them up to get at the disc. I found that the magnetic media disc was coming away from its metal centre. This does not bode well for any remaining old disks, as once they were inserted and spun up to speed, they disc might just separate from the metal centre. I think I will just scrap all the remaining disks.
And what about the 100Mb Zip drives, let alone the 8mm backup tapes!
