Diskette Drive Problems
If you see a diskette error message or have difficulty with a
diskette drive, follow these steps:
1. Try running the Diskette drives and controller diagnostic
test described in Appendix C. If the diagnostics program
indicates an error, consult your Epson dealer.
2. If you installed the drive yourself, did you carefully follow
all the instructions in Chapter 7? Review the instructions
and check all cable connections to make sure you have
installed the drive correctly.
3. Did you run the Setup program to define the correct type
of diskette drive as part of your computer’s configuration?
(See Chapter 2 for instructions.)
4. If you still have trouble with the drive, run the Diskette
drive and controller diagnostic tests described in
Appendix C. If the diagnostics program indicates an error,
contact
your Epson dealer.
5. If the diskette drive is making loud noises, do not attempt
any further examination of it. Contact your Epson dealer.
Note
Diskette drives may make different sounds accessing
different diskettes.
