A GARGLED UP DISK
We suggest you
regularly make a backup copy of
any
disk
which contains important programs or
data.
This way you won't have to worry about los-
ing them.
Also,
since a disk can actually get worn out
from
too
much use, it's a good
idea
to
make
a
backup
copy
of an old disk on a
new,
unused disk. Then,
when the
Computer
begins having its problems
reading and
writing to the disk, you can use your
backup copy.
Want to
make a backup copy? Get your
two
disks
ready:
1.
Your
"source" disk —This is the disk you want
to
duplicate.
Use any disk which has files stored
on it.
If you're just getting started, use the disk
which you worked with in
Chapter
2.
2. Your
"destination"
disk —This is the disk which
you
want
to be
your duplicate copy. Use a blank
disk or, if
you've been
using your disk system
for a
while, use any disk which contains files
you won't need
anymore.
After making some noise while it reads a portion
of your "source" disk, the Computer will print:
\'ote: Everything preciously
on your
destination dish
it- ill be erased. It will be replaced
with
all
the
data i
your
source disk.
If
your
"destination" disk is blank, you must
first
format
it. Remember how? Insert it in your
disk
drive, shut the door, and type
DSKINio
CENTER) .
Now make the backup copy. The
procedure
you
fol-
low depends on
whether
you
have one disk
drive
or
several.
Backup
with One
Disk Drive
If you
have
only one disk drive, it will take you
about
five minutes to make a backup copy. Insert
your "source"
disk in your disk drive and shut the
DRIVE
DOOR. Type
OIR
(ENTER) to see which files
you
will be copying.
Now
start the backup procedures. Type:
INSERT
DESTINATION DISKETTE AND PRESS CENTER;
Take the "source" disk out
and
insert
the
"desti-
nation" disk. Shut the
DRIVE DOOR.
Then
press
(ENTER).
You'll
hear some more
noise while the
Computer "writes" some things on the "destina-
tion" disk. Then it will print:
INSERT SOURCE
DISKETTE
AND
PRESS
CENTER)
The Computer will have you continue
switching
disks until you have copied everything from
your
source disk. During this process, make sure you
insert the correct disk and insert it properly. When
you've finished, the Computer will print the OK
message on your screen.
To make sure
BACKUP worked, you can insert
your "destination" disk and type D I R (ENTER) .
Backup with More Than One Disk
Drive
If you have more than one disk drive, backing up
a disk is much easier. It will take about two
minutes.
Insert your "source" disk
in drive
and your
"des-
tination"
disk
in drive 1
(Chapter
1
shows
how
to
label your drives). Then
type:
BACKUP CENTER)
BACKUP TO
i ( ENTER)
You will hear some noise as the Computer backs
up the contents
of
the disk in drive to the disk in
drive 1. When it's finished, it will print the OK mes-
sage. You can then make sure BACKUP worked
by typing
DIRi
CENTER).
You can use different drives, if you
want.
For
instance:
BACKUP
1 TO
(INTER)
backs up the contents of the disk in
drive 1
to
the
one in
drive
0.
