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. Did you reassign the diskette drives? If you are trying to
access a file on a diskette in drive A, for instance, and have
reassigned that drive as drive B, you cannot access the file.
As your computer processes the command, the light is lit on
the drive it is trying to access. See Chapter 4 for more
information about reassigning diskette drives.
8. 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.
9. 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. On a 5 '/+inch 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.)
