Do you have 5.25" and 8" floppy disks that are spare, low-quality, degrading, or just generally in bad shape?

I'd like to take my floppy disk data recovery game to the next level. I have equipment, but there's no substitute for experience. Therefore I'm looking for loose collections of old floppy disks to practice on. I'm especially interested in working with disks where the binder affixing the media to the donut is starting to fail.

I'm in London; will pay shipping; can pick up disks around here as well. Boosts are appreciated!

@stepleton oh hang on.
I think I still have some 5.25" disks that were recovered from (no joke) an abandoned level of a Welsh nylon factory.

I pulled them out of a literal carpet of dust 😅

I'll take a look later if you're interested?

@DosFox Sounds like a worthy challenge! I'd like to give them a go, but just remember that my objective is practice (so don't share them if they are valuable to you). Thanks!

@stepleton I'll see if I still have them!

I'm not terribly attached them - there is a chance I've already thrown them out 😅😅
