PARKING
HEADS
ON
MODELS
3650
AND
3675
In
the
month
of
July,
1988
MiniScribe's Recon facility
reported
that
76°A>
of
the
Model
3650
and
3675
drives arrived
with
the
heads
NOT
---PARKED-
at
the
"land1ng-zon~'
,which-on
these
models
is
Cylinder-
852.
As
you
know, drives "not landed"
could
seriously
damage
the
heads
and
disks
of
the
drives
when
they
are
in
transit.
resulting
in
high
scrap
cost.
and
possibly
voiding
the
warranty
of
the
drive.
We really
need
your
help
in
stressing
to
your
customers
and
fellow
employees
the
importance
of
"PARKING THE HEADS"
and
"proper
packaging"
of
the
drives for
shipping.
Here
are
the
steps
to
take
to
"park
the
heads"
and
"properly
package"
the
Model
3650
and
3675
for
shipping.
1.
Disconnect
both
ribbon
cables
from
the
hard
drive.
2. Remove
the
drive
select
jumper
from
either
DSO
or
DS!.
3.
Place
that
juniperon
the
pins
marked
JP3.
4. Apply
power
to
the
drive.
5.
In
approximately
30
seconds
the
heads
will
park
at
the
"landing
zone". You will
hear
the
stepper
motor
turn
as
it
moves
the
.
heads
to
the
"landing zone",
and
the
drives' LED
will
turn
amber,
indicating
the
heads
are
parked.
6.
Disconnect
power.
7. Place
the
drive
in
its
"Original"
anti-static
bag,
and
package
the
drive for
shipment
in
its
"original"
container.
If
the
drive will
not
spin
or
the
stepper
motor
and/or
its
circuitry
is
defective,
then
of
course
the
heads
cannot
be
parked.
In
this
case
it
is
imperative
that
the
drive
is
packaged
for
shipment
in
its
"original"
container,
thus
minimizing
the
possibility of
serious
damage
to
the
heads
and
disks.
Your
cooperation
is
vital
and
will
certainly
be
greatly
appreCiated.
Thank
you.
