3. Have you inserted the right type of diskette? The diskette
type normally appears on the manufacturer's label. Here are
the guidelines:
In a drive that has a storage capacity of 1.2MB, use
5 '/J-inch, double-sided, high-density, 96 TPI diskettes.
You can also use 360KB diskettes in this drive, but if
you write to a 360KB diskette in this drive, you may
have trouble using the diskette in a 360KB drive later.
In a drive that has a storage capacity of 360KB, use
5 '/+inch, double-sided, double-density, 48 TPI
diskettes. You cannot use 1.2MB diskettes in this drive.
In a drive that has a storage capacity of 720KB, use
3 '/z-inch, double-sided, double-density, 135 TPI
diskettes. You cannot use 1.44MB diskettes in this
drive.
In a drive that has a storage capacity of 1.44MB, use
3 '/l-inch, double-sided, high-density, 135 TPI diskettes.
This type of drive can also read and write to 720KB
diskettes.
See "Types of Diskette Drives" in Chapter 3 for more
information.
4. If your diskette is the right type for your drive, check to see
if the diskette is write-protected. On a 5 '/+-inch diskette,
there may be a write-protect tab over the notch on the side
of the diskette or there may be no notch at all. On a
3 '/I-inch diskette, the write-protect switch may be set to
the write-protect position or there may be no switch. You
cannot store or revise data on a write-protected diskette.
See Chapter 3 for information on write-protecting diskettes.
Some application programs do not function properly if the
diskette is write-protected. Check the program manual.
