Important Disk
Operations
In this
section
we
will
describe three very important operations:
1
.
Duplicating
the
trsdos
diskette
(backup)
2.
Initializing a data diskette
(format)
3.
Converting
files
from
Model

III
trsdos
(convert).
All
new
customers should complete
the
trsdos
backup
procedure now;
multi-
drive
customers should
also
complete
the
format
operation
for a
few
diskettes.
Detailed information
is
provided
later in this
manual;
here
we
will
simply
outline the procedures.
Making
a
BACKUP
(Duplicate) of
TRSDOS
Your
first
operation should be
to
duplicate
the
trsdos
diskette
you
received
from Radio
Shack.
The trsdos
diskette contains a
utility
program
called
backup
to
accomplish
this.
1
.
Locate
the
trsdos
diskette
and
a
new, blank
diskette.
The trsdos
diskette
will
be
referred to as the
"source," while the blank
one
will
be
called the
"destination," during
backup.
2. Start
trsdos
as
explained
in
the
previous
section.
TRSDOS READY
should be
displayed.
3.
Type:
BACKUP
(ENTER)
4.
trsdos
will
now
load
and
start
backup.
It
will
ask you:
SOURCE DRIVE NUMBER?
Specify the drive
which
contains the original
trsdos
diskette
by
typing:
CENTER)
Next trsdos
will ask:
DESTINATION DRIVE NUMBER?
Now
specify the drive
which
will
be used
for
making
the
duplicate
trsdos.
If
you have two
or
more
drives
in
your
system, type:
1
CENTER)
trsdos
will ask:
SOURCE DISK
MASTER PASSWORD?
Type:
PASSWORD
(ENTER)
(password
is
the
password
of the supplied diskette.)
Now'the
duplication process will begin.
If
the destination diskette
is
not formatted,
backup
will
format
it
before
continuing. (Before
any
diskette
can be used,
it
must be
initialized or
"formatted"
—
the
data regions defined
and
labeled,
and
a table of contents
or "directory'
1
created.)
