720KB drive-With this drive, use 3½-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-approximately 300 pages of text. 1.44MB drive-With this drive, use 3½-inch, doublesided, 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-approximately 600 pages of text. If your computer has more than one type of these drives or if you use diskettes from other computers, you need to be aware of certain incompatibilities between the drives and the diskettes they use. 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 contains data you want to erase. See Chapter 4 for instructions on formatting diskettes. 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 following tables summarize the possibilities and limitations. 5¼-inch drive/diskette compatibility Drive type 360KB 1.2MB Diskette types it can read from and write to 160KB, 180KB, 320KB, or 360KB 160KB, 180KB, 320KB, 360KB, or 1.2MB Using Your Computer 3-9

720KB drive-With this drive, use 3½-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-approximately 300 pages of text.
1.44MB drive-With this drive, use 3½-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-approximately 600
pages of text.
If your computer has more than one type of these drives or if
you use diskettes from other computers, you need to be aware of
certain incompatibilities between the drives and the diskettes
they use.
Note
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 contains
data you want to erase. See Chapter 4 for instructions on
data you want to erase. See Chapter 4 for instructions on
formatting diskettes.
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 following tables
summarize the possibilities and limitations.
