Diskette Problems
If you see an error message or have trouble accessing data on a
diskette, try the following steps:
1. You may have inserted the diskette upside-down or it may
not be inserted all the way. Remove the diskette and
reinsert it. If the diskette drive has a latch, be sure to turn it
down to secure the diskette. See Chapter 3 for detailed
instructions on inserting and removing diskettes.
2. If reinserting the diskette does not solve the problem and
you have access to another drive of the same type, place the
diskette in the other drive and repeat the operation. If you
can read the diskette, the trouble may be in your diskette
drive. See “Diskette Drive Problems” below.
3. Have you inserted the right type of diskette? For example, are
you trying to read a 1.44MB diskette in a 720KB diskette
drive?
4. Is the diskette write-protected? On a 3.5-inch diskette, the
write-protect switch may be set to the write-protect position
or there may be no switch. On a 5.25-inch diskette, there
may be a write-protect tab over the side notch or there may
be no notch. You cannot alter data on a write-protected
diskette. (Some programs do not function properly if the
diskette is write-protected.) See Chapter 3 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
documentation for instructions on formatting diskettes.
