A 2 MB Floppy can be perceived in one of two ways:
* 2 MB is the unformatted rated capacity of an HD diskettes. Once a 2 MB unformatted diskette is formatted, its capacity is 1.44 MB. These diskettes may have the "HD" logo impressed on the diskette somewhere, and there are two holes at the rear, or on the side opposite the diskette shutter, that are read by the drive mechanism to identify a diskette as an HD diskette.
* There is another format that has recently been release called ED (Extended Density). This diskette has an unformatted rated capacity of 4 MB, and a formatted capacity of 2.88 MB.
As of March, 1995 Apple does NOT manufacture computers that read or write to this format. These drives are found in the PC marketplace primarily.
