Question: I read somewhere that floppy disks cannot be partitioned with most modern computer software tools. However, can’t a floppy disk simply be viewed as an array of bytes like other magnetic storage devices? What prevents you from creating a boot sector and implementing some kind of partition map (e.g. MBR) like you can with a hard disk?
Answer: You certainly can partition a floppy. Nothing prevents you from doing it, and it should work just fine on Linux when you mount it.
But given the small amount of data you can store on a floppy, having several partitions doesn’t make sense, so it’s just a waste of space. That’s why nobody is doing it.
Also, most tools (and old OS like DOS) will be confused by a partition table, and won’t work correctly any more.
