The
FORMAT
and
BACKUP
Commands
When you
put information
on
a
diskette, it is
important
to
make
a copy. In an instant, you
can lose
weeks
of work
as a result of:
•
Worn-out
or
mishandled diskettes
•
Mishandled
equipment
•The
power going
out while you're
using the
computer
To avoid
this,
you should make
backup copies
of
your diskettes
at regular intervals.
Begin
now by copying
your
master TRSDOS
System
Diskette
and use the
copy from now on.
Note:
The TRSDOS
System Diskette
is
a
single-sided
diskette. Initially,
you
should
copy
it to
a single-sided diskette.
Later,
you can
copy
TRSDOS
to
a dou-
ble-sided
diskette
to increase the
amount
of
data you can place
on the
system
diskette.
To
make
a copy, you must first
use the FOR-
MAT
command
to organize
a blank diskette
into
a
filing system
in which
you can put disk
files.
Then,
you
must
use the
BACKUP com-
mand to copy all the
files from your
system
diskette to the formatted
diskette.
Follow
the steps below:
1. Insert
a blank, single-sided
diskette
into
Drive 1.
(Be sure the diskette's
write-protect
notch
is not covered
by a foil tab.) Close
the drive door.
2. At
"TRSDOS Ready,"
type:
FORMAT
:1 (Q
=
N)
INTER]
(Be sure
to type the number
"1,"
not
a
lower-case letter
"L."
This tells TRSDOS
to
format the diskette
in Drive
1.)
