Oh well.... I gave up on floppy disks when I reached a point where none of them were readable anymore. They never had a very long shelf life. Back in the day I had to redo a semesters worth of homework over when both my main floppy and my backup copy were unreadable.I assume it wasn't helped by it being winter and 10 degrees out. It wasn't a terribly long walk to class but I still think they failed from the cold.
FYI. If anyone still has floppy disks, and would like to erase them before getting rid of them: https://www.amazon.com/floppy-disk-reader/s?k=floppy disk reader
That works but any magnet will get the job done. And if you're just throwing them away you can rip them apart and cut them up fairly easily.
I still used ZIP drives from Iomega until 2002. I believe it was built-in, but I also had an external drive version. https://en.wikipedia.org/wiki/Zip_drive
