Use the Display Partition Information option of the FDISK program to see if your hard disk has an active (bootable) DOS partition on it. (See the MS-DOS Reference Manual for instructions on using FDISK.) If it does not, back up all your hard disk files and then reinstall MS-DOS on the hard disk. See your MS-DOS Installation Guide for instructions.

If your hard disk does have an active DOS partition, back up all your hard disk files and then try reformatting your hard disk using SELECT. See your MS-DOS Installation Guide for instructions.

Caution

Reformatting destroys all the data currently on your hard disk, so do this only after careful consideration and after trying the preceding steps.

If the diagnostics program indicates an error, contact your Epson dealer. Never open the sealed unit that encloses the hard disk.
