Drive and diskette incompatibilities
Because of the size difference, you cannot use 3½-inch diskettes in a
5¼-inch 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.
