3. Check to see if you have inserted the right type of diskette.
For example, are you trying to read a 1.44MB diskette in a
720KB diskette drive? See “Types of Diskette Drives” in
Chapter 1 for more information.
4. If your diskette is the right type for your drive, see if it is
write-protected. On a 5.25-inch diskette, there may be a
write-protect tab over the notch on its side or there may be
no notch. On a 3.5-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 1 for more information.
5. Is the diskette formatted? A new diskette must be formatted
before you can store data on it. See your operating system
manual for instructions on formatting diskettes.
6. Did you receive one of the following MS-DOS error
messages?
If you see one of these messages, make sure the diskette is
properly inserted in the drive. If the problem persists, try
removing the diskette and reinserting it.
If the error message still occurs, you may have a defective
diskette. Try copying the files from the bad diskette to a
new diskette.
