5. If your diskette is the right type for your drive, see if it is
write-protected. On a 5 diskette, there may be a
write-protect tab over the notch on its side or there may be
no notch. On a 3
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.
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 the Setup program again to
check the setting. See Chapter 2 for instructions.
8. Did you receive one of the following MS-DOS error
messages?
Disk Drive Error: Abort, Ignore, Retry?
Disk error reading drive d:
Disk error writing drive d:
If you see one of these messages, make sure the diskette is
properly inserted in the drive. On a 5 diskette drive,
make sure the drive latch is closed. Try the operation again.
If the problem persists, try removing the diskette and
reinserting it. This may solve the problem if the diskette was
not seated properly in the drive.
If the error message still occurs, you may have a defective
diskette. Use the MS-DOS COPY command to copy the
files from the bad diskette to a new diskette. (See your
MS-DOS Reference Manual for instructions.)
