Floppy disks have a finite usable life. Depending on where and how you have been storing them, they may be shot.
Yeah, but.... I tried three of 'em, three different OEM, and three ages, and they all give me fdisk saying it's not a valid block device.
If they were all written with the same drive it's also possible the head alignment had drifted which will make things...interesting.
Try formatting a scratch floppy to see if you can write. If that works but you still can't read, evidence that it's indeed an alignment mismatch.
