Since you may swap diskettes this way often, it is easy to forget which diskette is which. One way to avoid accidentally losing data is to hold the diskette for one drive in your left hand and the diskette for the other drive in your right. You can also place a write-protect tab on your source diskette. For more information on using a single floppy disk drive with MS-DOS, see your MS-DOS manual.

Using a Hard Disk Drive

The internal hard disk for the Equity II has a capacity of 20MB, or about 20 million characters. This is equivalent to approximately 60 doubledensity floppy disks. Using a hard disk reduces the number of floppy disks you need and eliminates much of the disk-swapping you do when you use floppy disks. You can do almost all your work on the hard disk and copy files to floppy disks as needed (to make backups, for exam- ple).

Although the hard disk is very reliable, be sure to back up all your hard disk files on floppy disks in case you lose some data accidentally. You use the MS-DOS ARCHIVE program to back up your hard disk files.

To ensure you always have plenty of storage space available, keep only files you use regularly on the hard disk and store your other files on floppy disks.

Before you can use the Epson internal hard disk, you must do the following to prepare it:

Use the MS-DOS SETUP program to tell your system it has a 20MB hard disk.Use the MS-DOS HDPART program to partition the hard disk to run MS-DOS.

Format the MS-DOS partition with the MS-DOS HDFORMAT program and use the /S option to copy MS-DOS to the hard disk.

Use XTREE® or the COPY command to copy the MS-DOS utility programs to the hard disk.
