@drchaos @cub80_appleby @futurebird there were some brands for which I was able to figure out how to pop open the plastic case with a metal nail file so I could get a disk out of a damaged case and put it in a good case to try to rescue some data off it. But other brands I couldn't figure out how to do it without breaking the plastic. Mostly it was much easier to just copy stuff onto 3 or 4 floppies for backup purposes, though that required some foresight and prior planning.
