If you

using a
single-drive
system,
trsdos
will
prompt you to
swap
source
and
destination
diskettes
several
times
during the
formatting/backup
process.
After a
single-drive

Making a
Data
Diskette
(FORMAT)
This
section
applies
to
multi-drive
systems only.
Drive
must
always
contain a
trsdos
diskette, so
the
Computer
can
have
access to
the
system
programs
stored
there.
Much
of the
storage
capacity of this
diskette
is
taken up
by the
system
programs.
However, the
other
drives
in the
system
may
contain
"data"
diskettes
which
have no
system
programs.
All of the
storage
capacity
of such
diskettes is
available
for
your
programs and
data.
The
format
utility
program takes
a
diskette
and
initializes
or
"formats" it.
If the
diskette
was
previously
formatted,
all
prior
information
can be
lost.
The
resultant
diskette
contains
no
system
files and
may
only be
used
in
Drive
1
, 2
or
3
.
