160KB or 180KB diskettes.) These diskettes contain 40

tracks per side and 8 or 9 sectors per track. With 8 sectors

per track, a diskette holds up to 320KB. With 9 sectors per

track, a diskette holds up to 360KB of information

You must format a new diskette before you can store data on

it. See “Formatting Diskettes,” later in this section.

If your computer has more than one type of diskette drive, or if

you use different types of diskettes, you need to be aware of

certain incompatibilities between the drives and diskettes.

Because of the type and size differences, you cannot use a

 diskette in a 

 drive or vice versa. There are

also limitations on using diskettes that are the same size as the

drive but have different capacities. The following tables

summarize the possibilities and limitations.
