Ll 1.44MB drive-with this drive, use 3 ‘/z-inch, double-sided, high-density, 135 TPI, 1.44MB diskettes. These diskettes contain 80 tracks per side, 18 sectors per track, and hold up to 1.44MB of information, which is approximately 600 pages of text.

CI 360KB drive-With this drive, use 5 ‘/+inch, double-sided, double-density, 48 TPI, 360KB diskettes. (You can also use single-sided, 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, which is approximately 150 pages of text.

Cl 720KB drive-With this drive, use 3 ‘/z-inch, double-sided, double-density, 135 TPI, 720KB diskettes. These diskettes contain 80 tracks per side, 9 sectors per track, and hold up to 720KB of information, which is approximately 300 pages of text.

Note

You must format a new diskette before you can store data on it. See “Formatting Diskettes,” later in this section.

Drive and diskette incompatibilities

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.

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

3 ‘/z-inch diskette in a 5 ‘/+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 possibilities and limitations.
