- Oh yes it does. It doesn't need to have a filesystem (and if it does,
- the filesystem will be overwritten), but unless the floppy is formatted
- the drive won't be able to write anything to it.

- There is a distinct difference between formatting a disk and creating a
- filesystem on it. Since the MS-DOS format-command does both, many
- people seem to think there is no difference.
-
- Formatting means that the magnetic stuff on the disk is magnetized in
- a specific way. Before it is formatted, the contents of the disk are
- basically random fluctuations of magnetism, and as should be clear it
- can be very difficult to find anything useful in random disturbances.
-
- Creating a filesystem means that the some information is written to the
- disk so that the operating system can take care of allocating space for
- files, keep lists of files, etc.
