3. If reinserting the diskette does not solve the problem and
you have access to another diskette drive of the same type,
place the diskette in the other drive and repeat the
operation. If this works, the trouble may be in your diskette
drive. See “Diskette Drive Problems,” below.
4. Check to see if you have inserted the right type of diskette.
Follow these guidelines:
In a 1.2MB drive, use 5¼-inch, double-sided, high-
density, 96 TPI diskettes. You can also use a 360KB
diskette, but if you write to it in this drive, you may
have trouble using it in a 360KB drive later.
In a 1.44MB drive, use 3½-inch, double-sided, high-
density, 135 TPI diskettes. This type of drive can also
read and write to 720KB diskettes.
In a 360KB drive, use 5¼-inch, double-sided, double-
density, 48 TPI diskettes. You cannot use 1.2MB
diskettes in this drive.
In a 720KB drive, use 3½-inch, double-sided, double-
density, 135 TPI diskettes. You cannot use 1.44MB
diskettes in this drive.
See “Types of Diskette Drives” in Chapter 3 for more
information.
5. If your diskette is the right type for your drive, see if it is
write-protected. On a 5¼-inch diskette, there may be a
write-protect tab over the notch on its side or there may be
no notch. On a 3½-inch diskette, the write-protect switch
may be set to the write-protect position or there may be no
switch. You cannot alter data on a write-protected diskette.
(Some application programs do not function properly if the
diskette is write-protected. Check the program manual.)
See Chapter 3 for more information.
