Write-Protecting Floppy Disks; Making Backup Copies - Epson Equity I User Manual

Write-protecting floppy disks

The right edge of a floppy disk has a small, rectangular notch as
shown in Figure 4-1. If this notch is not covered, you can write new data
to the disk. If it is covered with an adhesive write-protect tab, you can
read data on the disk but you can not write new information to it or
delete any files. If you try to change the information on a write-protected
disk, an error message usually displays a warning that the disk is write-
protected. Write-protect tabs are usually included with new disks.

Making backup copies

It is a good idea to keep a second backup copy of all your important
data and program disks. With program disks, or the system master disks
supplied with your Equity, you should make backup copies to use, and
keep the originals in a safe place-away from your working disks. With
data disks, you should make up-to-date backups regularly (preferably
daily), and keep them apart from the originals.
Your MS-DOS manual describes how to make a backup of your
MS-DOS system disk. To make regular backups of other MS-DOS disks,
use the DU (Disk Utility) program or the DISKCOPY command. "Using
a Hard Disk Drive," below, gives more information on backing up hard
disks.
