On Windows there is a command called "diskcopy" for copying one floppy to another.
diskcopy A: B: /v
My understanding is that this is a sector based cloning tool, and so it should work for floppies, hard drives, ssds, and even cds/dvds. Yet, various sources on the net, including Microsoft, say that it can ONLY be used for copying floppy devices, and CANNOT be used for cloning hard drives. However no one ever explains why.
