Note:
The number
of
times the DUP program prompts you to
insert
the source and destination
diskettes
depends on the num-
ber and size of
the
file(s) 10 be duplicated for a given system and
the
amount
of RAM in the system
.
Duplication Using Multiple Disk Drives
If
you are using both the ATARI 810 and XF551
Disk
Drives,
distinguish between files stored
using
the single-density and
enhanced-density formats when labeling the
diskettes.
This
will keep you from using them
in
the wrong disk
drive.
For a multiple disk drive
system,
it is
also necessary to save a
RAM-resident
BASIC
program
,
as the user's program area will
be altered and MEM.SAV will be
invalidated
.
Notice
that
the
source
diskette
is
inserted in
Drive
1 and the destination diskette
in Drive
2.
This process
can
take
several minutes
if
the source diskette
is
almost
full.
