Backup Limited
Diskettes
Some software products distributed by Radio Shack come on backup
limited diskettes. This means that you can make only a fixed number
of copies of the master diskette that you receive. You should use the
master diskette to make only the backup copies that you will use, as
you cannot make a backup copy of a backup that was made from a
backup limited diskette.
These diskettes are clearly marked to indicate that they are backup
limited.
If
you are uncertain, contact your Radio Shack Computer
Center or the store where you purchased the diskette.
When you have exhausted the number of copies you are allowed to
make or if the master diskette is write protected, the following
message appears when you attempt to back up the diskette:

Making
a Backup
Copy
Before you make a copy of a backup limited diskette, you must
remove the write-protect tab from the diskette (if one is present).
Because the diskette
is
not write-protected, you should be very
careful that you do not accidentally format the master diskette or back
up the blank diskette to the master diskette.
Follow the steps given below for systems with two or more floppy
drives or systems with one floppy drive, as appropriate.
For
systems
with
two
or more floppy drives:
(If you have a hard disk system and two or more floppy drives, start
up as a floppy disk system and use this procedure.)
1.
Insert a TRSDOS system diskette into floppy Drive
0.
Insert a
blank diskette into floppy Drive
1.
2.
Format the blank diskette, following the directions given with the
FORMAT utility. (You can use the command FORMAT
:1
(0
=
N)
CEHllID
to produce a default diskette.)
If
the diskette has any flaws on it (that is, if an asterisk
is
displayed next to one or more cylinder numbers), repeat step 2
with another blank diskette. Remember that you can make only a
fixed number of copies of this diskette, so you should try to use
good media.
