If your computer has more than one type of diskette drive, or if
you use diskettes from other computers with other types of
diskette drives, you need to be aware of certain incompatibilities
between the diskette drives and the diskettes they use.
Drive and diskette incompatibilities
Because of the size difference, you cannot use 3 diskettes
in a 5 drive or vice versa. There are also certain
limitations on using diskettes that are the same size as the drive
but have different capacities. The tables below summarize the
possibilities and limitations.
