Epson Progression U12 - Manual (Page 167)

7. If you see no error messages but there is something wrong
with the data in a file, the operating system or an
application program may have updated the storage
information on the diskette incorrectly. This is probably the
case if you have one of these problems:
Part of a file is missing
A file includes parts of other files
An expected output file is missing.
If you are using MS-DOS use CHKDSK to make the necessary
repairs; see your MS-DOS manuals for instructions. You
may also have some special diagnostic software you can
use to check your diskettes.
Diskette Drive Problems
If you see a diskette error message or have difficulty with a
diskette drive, follow these steps:
1. If you have problems with a new diskette drive that your
dealer installed for you, consult your dealer about the
problem.
2. If you installed the drive yourself, did you carefully follow
all the instructions in Chapter 4? Review the instructions
and check all the cable connections to make sure you have
installed the drive correctly.
3. Did you run the SETUP program to automatically configure
the correct type of diskette drive as part of your system?
(See Chapter 2 of the Setup Guide for instructions.)
4. Try running the Diskette drive diagnostic tests described in
Chapter 5. If the diagnostics program indicates an error,
contact your Epson dealer.
