SYS C:

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.
