diskette to the root directory of the hard disk, log onto the
diskette drive, type the following command, and press Enter:

4. If you can boot from a diskette, but cannot access data stored on
your hard disk, you may have accidentally repartitioned or
reformatted part or all of the disk.
Use the FDISK program to see if your hard disk has an active
(bootable) DOS partition on it. If it doesn’t, back up all your files
and then use FDISK to create an MS-DOS partition. If your hard
disk does have an active DOS partition, back up all your files and
then try reformatting your hard disk using FORMAT or
SELECT Reformatting destroys all the data currently on your
hard disk, so do this only after careful consideration and after
trying the preceding steps.
5. If you are still having problems, you can try using the Format
Hard Disk option of the OPERATION MENU on the Reference
diskette. This procedure performs a hardware check and format
of a hard disk. See Appendix D for details. You may want to
contact your dealer before using this option.
6. If none of the above procedures work, contact your Epson dealer
or have an Authorized Epson Customer Care Center check your
hard disk. Never open the sealed unit that encloses the hard disk.
Software Problems
If you are having trouble with a software program, try the following
solutions:
1. If a software program does not start, check that you are following
the correct procedure for starting the program. If you have a hard
disk, make sure you are logged onto the directory containing the
application program. If you don’t have a hard disk, make sure
you have inserted the application diskette in the top drive.
