Note
You must format new diskettes before you can use them
with an operating system. Formatting erases all the data on
a diskette and prepares it to receive new data, so be sure to
format only new blank diskettes or diskettes that contain
data you want to erase. See Chapter 5 for instructions on
formatting diskettes.
Drive and diskette incompatibilities
Because of the size difference, you cannot use 31/2-inch
diskettes in a 51/4-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 following tables
summarize the possiblities and limitations.
