Making backup copies
Copy all diskettes that contain programs, as you did the master system
diskettes that come with the Equity Ie, and use only the copies. Store your
original system diskettes in a safe place away from your working diskettes.
Copy your data diskettes (or hard disk files) regularly, as often as you update
them. Store backup diskettes away from the originals.
Chapter 1 describes how to make a backup copy of your Equity Ie
system
diskettes. For general instructions on copying diskettes or hard disk files, see
Chapter 4.
Write-protecting diskettes
You can write-protect a diskette to prevent its data from being altered. When
a diskette is write-protected, you can copy data from it, but you cannot store
new data on the diskette or delete any files it contains. If you try to change
data stored on a write-protected diskette, an error message is displayed.
The write-protect device is a small switch on the lower-right corner on the
back of the diskette. To write-protect the diskette, slide the switch down
toward the edge of the diskette so there is a hole where the switch used
to be.
switch
To remove the write-protection, move the switch up toward the center of the
diskette so the hole is covered.
