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. For example, are you trying to read a 1.44MB diskette in a 720KB diskette 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 5 N-inch diskette, there may be a write-protect tab over the notch on its side or there may be no notch. On a 3 M-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 information.

6.Is the diskette formatted? A new diskette must be formatted before you can store data on it. See your MS-DOS Reference Manual for instructions on formatting diskettes.

7.You may have entered an incorrect diskette drive type when you ran the SETUP program. Run SETUP again to check the setting. See Chapter 2 for instructions.

8.Did you receive one of the following MS-DOS error messages?
