$0 Floppy disk is trying to be repaired

USB floppy drives, freedos and Norton disktool are trying to fix the floppy disk but fail every time. Welp, at least I tried. Those floppy disks are so damaged(physically and magnetic), the disktool are make the best progress around 4% and died(the drive terminated something I forgor). By the way, this video is posted at midnight(for me) so there is no music, just the timelapse, well at least it's 60fps. uhh... ffmpeg's concat is stupid.
