Diskcomp
[E]@
The Diskcomp
switches
Diskcomp
Purpose:
Compares
the
contents
of
the
disk in
the
source
drive
to
the
disk
in
the
target drive.
Syntax:
diskcomp
[drive:] [drive:]
[/1]
[/8]
Comments:
The
first
drive:
option
specifies
the
drive
that
contains
the
source
[
disk, and
the
second
drive:
option
specifies
the
drive
that
contains
the
target disk.
If
you specify only
one
drive,
diskcomp
uses
the
default
drive
as
the
target drive.
If
you
specify
the
same drive as
the
source
and
target,
diskcomp
does
a comparison using
one
drive, and
prompts
you
to
insert
the
disks as appropriate.
The
II switch causes
diskcomp
to
compare
just
the
first side
of
the
disk, even if
the
disks and drives that
you
are
using are
double-sided.
The
/8 switch causes
diskcomp
to
compare
just
the
first 8 sec-
tors
per
track,
even
if
the
disks
contain
9
or
1 5
sectors
per
track.
Diskcomp
performs a track-by-track comparison
of
the
disks.
It automatically determines
the
number
of
sides
and
sectors
per
track based
on
the
format
of
the
source
disk.
If
the
target disk
is
not
the
same type as
the
disk in
the
source
drive,
diskcomp
displays
the
following message:
Drive
types
or
diskette
types
not
compatible
If
all
the
tracks are
the
same,
diskcomp
displays
the
message:
Compare
OK
[
If
the
tracks are
not
the
same,
diskcomp
displays a "Compare
error"
message that includes
the
track
and
side
number
where
it
I
found
the
mismatch. L __
When
diskcomp
completes
the
comparison, it
prompts
you
with
the
following message: [ -
Compare
another
diskette
(Y/N)?_
