INTRODUCTION
(cont.
)
Each
hard
disk
drive
sold
by
North
star
has
an
information
label
attached
to
the
side
of
the
drive.
The
label
indicates
the
name
and
size
of
the
drive
as
well
as
the
location
of
bad
spots
on
the
disk.
You
will
need
this
information
during
the
hard
disk
format
process.
In
order
to
facilitate
the
use
of
data
on
the
information
label,
a
blank
label
is
included
as
part
of
each
installation
kit.
Copy
the
data
from
the
label
attached
to
your
hard
disk
drive
to
the
blank
label.
Attach
the
new
label
to
the
outside
of
the
rear
panel
of
your
HORIZON.
When
you
are
ready
to
format
the
hard
disk,
you
then
have
access
to
the
required
information
without
removing
the
cover
of
your
HORIZON
computer.
Hard
disk
drives
are
sensitive
to
mechanical
shock
and
should
be
handled
with
care.
Dropping
or
jarring
a
drive
can
cause
damage
to
the
read/write
mechanism
and
may
result
in
a
loss
of
data.
Take
the
following
precautions
when
handling
your
hard
disk
drive:
o
Do
not
remove
the
drive
from
the
shipping
container
until
you
are
ready
to
insert
it
into
the
computer.
o
Never
place
the
drive
on a
hard
surface,
such
as
a
table.
Place
a
pad
on
the
surface,
then
rest
the
drive
on
the
pad.
Normally,
DC
power
cables
for
HORIZON
disk
drives
connect
directly
to
sockets
which
are
integral
to
the
disk
drive
circuit
boards.
An
exception
to
this
occurs
when a
MiniScribe
HD-IS
hard
disk
drive
is
installed.
The
MiniScribe
hard
disk
drive
has
apower
harness,
rather
than
a
socket,
attached
to
its
circuit
board.
To
supply
power
to
this
disk
drive,
you
must
connect
the
HO~IZON
DC
power
harness
to
the
MiniScribe
power
harness.
