Superfloppy is Microsoft's term for any disk that does not contain a partition table. The entire disk -- whatever its size -- is treated as a single partition. Whether a partition table is present/required is determined by the media type, and/or the boot program in the first physical sector and/or the software that the boot program invokes. Superfloppies are still "block devices" and are treated by Microsoft OSes as disk drives. They may get a different Icon than partitioned "drives", but are otherwise not distinguishable from the user point of View.

Probably the best known Superfloppies are the Iomega ZIP drives.
