Making Backup Copies
It is important to make copies of all your diskettes. Make
backup (working) copies of all diskettes that contain programs,
such as your operating system and Reference diskettes; then
use only the copies. Store the original diskettes away from your
working diskettes. Also, copy your data diskettes as necessary
to keep your files up-to-date.
You’ll probably use your hard disk to store the programs and
data files you use regularly. Keep backup copies of all these
files on diskettes.
You can copy your data in several ways. See your operating
system manual for instructions.
Using a Single Diskette Drive System
MS-DOS expects a computer to have at least two diskette drives
(A and B), and displays prompts and messages accordingly.
Your ActionNote supports one 3.5-inch external diskette drive;
this is drive A. MS-DOS uses the one drive as two by
displaying alternate prompts for the source and target diskettes.
For example, if you need to make a copy of a diskette, you can
insert the diskette in drive A and enter the following command:
DISKCOPY A: B:
MS-DOS copies the data from drive A (the source diskette) to
its memory and then prompts you to insert the diskette for
drive B. At this point, you remove the original diskette, insert a
blank diskette (the target diskette), and press any key to
continue. Then MS-DOS copies the data from its memory to the
target diskette.
