You can't access the external diskette drive.
Make sure the disk drive cable is connected securely to the
external disk drive port.
Your data files are damaged or corrupted.
Refer to your program documentation for file recovery proce-
dures. Many programs automatically create backup files.
You may also be able to recover lost data by using a disk utility
program, which is available from your dealer. (If the Explorer
window doesn't display all the files you think should be stored in
the directory, recovering data is unlikely.)
Some programs run correctly, but others do not.
This is probably a configuration problem. When a program
doesn't run properly, refer to its documentation and check that the
hardware configuration meets its needs.
A diskette won't go into the external disk drive.
You may already have a diskette in the drive. Make sure the drive
is empty.
You may be inserting the diskette incorrectly. Hold the diskette by
the label with the hub side facing down, and insert it so the metal
head window cover goes into the drive first.
The metal cover or a loose label may be obstructing the path into
the drive. Carefully inspect the diskette. If the metal cover is loose,
replace the diskette. If the label is loose, replace the label and try
inserting the diskette again.
