Installation Overview
Installation of the drive can be divided into distinct
phases as outlined below. Some of these may not be
applicable to your particular installation requirements.
Refer to the individual drive installation sections for
specific information on your drive model.
• Drive configuration: The user must select which of
the drive features are appropriate to enable for installation in their system. This is done by way of the user
configuration jumpers found on the drive PCB.
• Mechanical installation: After setting up the drive
configuration the drive must be mechanically installed into the host system and the power and I/O
cables attached. Previously mentioned precautions
should be observed
• SCSI drives should not be defined in the CMOS:
The SCSI Host adapter has its own BIOS to handle
the Input/output procedures. The CMOS setting for
SCSI drive is either drive type zero, or the "no drive
installed" option.
Page 11
Hawk 4 (Wide) Family Install Guide, Rev. A 9
___________________________________________
• Low-level formatting: After the drive has been
properly configured for the system, it does not need
to be low-level formatted, as this has been done by
the factory and does not require this step during
installation. (The low-level format writes the sector
boundaries and track information to the drive). Defect
management information is read from the drive by the
host system when required in the installation procedure. If an installed drive is low-level formatted, all
user data stored on the drive will be lost.
Note. Seagate Technology assumes no liability for
lost user data.
• Partitioning and high level formatting: A drive can
be sub-divided into "partitions" which behave as
individual drives within the system. See your system
documentation. Present day drive installation programs have menus that lead you through these
installation procedures.

Product repair information
Service requirements
The special facilities required for the manufacture of
these drives generally prohibit repair in the field. If
problems occur during installation, please contact your
supplier for assistance. Do not attempt to disassemble
or repair. Drives should be sent to the repair depot
through the purchase source, if possible. Please observe the following cautions.
Caution.
• Handle drive with care. Do not drop or bump hard.
• Never remove the cover of these disc drives. Servicing items in the sealed HDA (heads, media, actuator, etc.) require special facilities. The drive contains
no user purchasable parts or PCBs.
• Opening the sealed HDA voids the drive warranty.
• Applying a soldering device to the components on the
PCB voids the drive warranty.
• Place drive on a flat, static dissipative surface and
handle with extreme care. Always follow all EOS/
ESD precautions to avoid damage to the electrical
assemblies.

Hawk 4 (Wide) Family Install Guide, Rev. A 11
___________________________________________
Shipping: When transporting or shipping a drive, a
Seagate approved container must be used. Keep your
original box. They are easily identified by the Seagate
Approved Package label. Shipping a drive in a nonapproved container voids the drive warranty.
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in
transit. Contact your Authorized Seagate Distributor to
purchase additional boxes. Seagate recommends shipping by an air-ride carrier experienced in handling
computer equipment.
Product repair and return information
Seagate customer service centers are the only facilities
authorized to service Seagate drives. Seagate does
not sanction any third-party repair facilities. Any unauthorized repair or tampering with the factory-seal voids
the warranty.

Initial setup information
For the initial setup connect the cables, set the SCSI
bus address and enable or disable (as required by
system configuration), the SCSI I/O line terminator
resistors (model "W" drives only). Note whether the
drive model number ends in W, WC, DC or WD. These
procedures are described in paragraphs following.
SCSI interface cable connection
The drives covered by this manual are SCSI interface
drives. For "W" and "WD"" models, system connection
is via a 68 pin, SCSI connector. For "WC and DC"
models system connection is via an 80 pin SCSI
connector. Normally "WC and DC" models plug directly
into a PCB or bulkhead mounted mating 80 pin connector. Interfacing "WC and DC" models via a cable is not
recommended. Pin 1 is noted in Figures 1a and 1b.
Some cables have a contrasting color stripe on one
edge to indicate pin 1. The I/O connector is keyed by
virtue of its shape. There is only one way it can mate
with the mating input connector. Strain relief is recommended at the cable for drives using cables.
block system cooling air flow in routing of cables.
Do not
DC Power connection
Model ST15230W/WD family drives receive DC power
through a 4 pin connector mounted on the PCB next to
the SCSI I/O connector. See Figure 1.

___________________________________________
Figure 1. DC power connection, 68 pin SCSI I/O
connector
ST15230WC and ST15230DC model drives receive
power from the host computer through the 80 pin
combined SCSI I/O and power connector (not shown,
since a separate DC power cable not required). No
separate DC power connector is provided on the drive.
SCSI address selection
On "W" and "WD" model drives, make sure that the
SCSI bus address jumper plugs are properly set for the
bus address assigned to the drive. In some systems, a
cable plugs into either J6 or J1auxiliary, so drive ID can
be set at some remote location. See Figures 3a and 3b
showing the bus address select header and the jumper
configurations that select addresses 0 through 15. ID 7
has the highest priority during bus arbitration on (both
8 and 16 device systems). Bus arbitration priority
decreases to ID 0, then ID 15 down to ID 8. ID 8 is the
very lowest priority. Typically the primary boot device is
set to ID 0 the host is ID 7, and the subsequent SCSI
drives are jumpered as appropriate for the particular
system involved.
Page 21
Hawk 4 (Wide) Family Install Guide, Rev. A 19
___________________________________________
If the drive LED shows no on/off activity when the host
is trying to communicate with it, an incorrect bus
address selection at the drive (or remote ID select
location) should be suspected.
On "WC and DC" model drives the SCSI ID can be and
presumably will be, set over the 80 pin interface by the
host computer. Unless directed to do so by the system
documentation, no jumpers should be installed for
address selection. On "WC and DC" model drives, the
host system also has complete control over motor start
functions, so no Motor Start or Delayed Motor Start
Jumpers should be installed.
Terminator resistor packs
Model ST15230W family drives have I/O line terminator
resistors that are permanently installed, but can be
enabled or disabled by jumper plug. See jumper in
Figure 3a. If you are installing a single drive, the
terminator resistors must remain enabled. If you are
installing multiple hard disc drives, disable the termination resistors from all the drives but the one connected
to the end of the SCSI I/O cable.
Page 22
20 Hawk 4 (Wide) Family Install Guide, Rev. A
___________________________________________
Model numbers that end in "WD and DC" have differential I/O circuits and these drives and "WC" model drives
have no provisions for terminators on the drive PCB.
The system manufacturer must provide some external
means of I/O line termination. The ST15230W/WD
drives can provide power for external terminators if the
TP jumper is installed on the last position on the right
end of J2. See Figure 3a. Do not mix "W" model and
"WD" model drives on the same I/O bus. Do not mix
"WC" and "DC" model drives on the same bus.
Read/Write head auto-park
Seagate disc drives described herein mentioned in this
drive park the heads automatically at power off. This
feature requires no operator intervention.
Optional parity bit enable
Some systems require parity bit checking. Consult the
system documentation for the specific requirements.
See Figure 3a for location of Parity Bit enable jumper.
Jumper-installed enables parity reporting by the SCSI
bus.
Write precompensation and reduced write
current
Not required on Seagate SCSI Interface drives covered
by this manual.

Drive configuration
Each disc drive has option select header connectors on
the back, side and front where jumper plugs are installed to select the way that the drive is to be configured and to select its ID (0 - 15) on the I/O bus. See
"Initial set-up information" and see notes following
Figure 3b.
ST15230W/WD family 68 pin SCSI I/O drives
On Hawk 4 family, W/WD model drives either J6 (on the
front of the drive) or J1-auxiliary (at the rear, beside the
DC Power connector) may be used to set the drive ID.
To avoid possible incorrect ID setting, do not use both
J1-auxiliary and J6 for ID selection. The following
figures show where these headers are located on the
different drives covered by this manual. See notes
following Figures 3a and 3b where explanations are
given about the purpose of each jumper and specify the
standard factory (called "default") settings of these
jumpers (i.e., settings used for most common single
drive application). Changes to these settings should be
made only if it is known that the system requires a
different configuration.

___________________________________________
ST15230WC/DC family 80 pin SCSI I/O drives
On Hawk 4 family, ST15230WC/DC model drives there
is no J1-auxiliary. J6 can be used to set drive ID, but the
host probably does it over the 80 pin interface. J6 may
be used to drive the external drive activity LED. This is
described in the notes following Figure 3b.

Notes for Figure 3a, 3b and 3c:
[1] Notes explaining the functions of the various jump-
ers on jumper header connectors J2, J1-auxiliary
and J6 are given below in left to right order of
jumper position. The term "default" means as
standard OEM units are configured when shipped
from factory. "Off" means no jumper is installed;
"On" means a jumper is installed. Off or On underlined is factory default condition.
[2] The PCB on "WC and DC" models does not have
connector J1-auxiliary, but has a single 80 pin
combined SCSI I/O and DC power connector instead of the 68 pin SCSI I/O and 4 pin DC power
connectors. Included among the 80 pins are the
SCSI ID, Motor Start and Delayed Motor Start
select functions, and the remote LED signal. Do not
use J2 and J6 for these five functions if the host
uses the ones included in the 80 pin connector.
[3] Drive ID may be established by installing jumper
plugs in one of the patterns shown in Figures 3a, 3b
and 3c, or by plugging onto J6 or J1-auxiliary a
cable that leads to an external ID selection circuit.
Both jumper plugs and an external ID selection
source should not be used. See [4] for other functions of these two headers that are time-shared
with the drive ID function.

28 Hawk 4 (Wide) Family Install Guide, Rev. A
___________________________________________
[4] The drive time-shares the ID and LED functions of
J6 and J1-auxiliary. That is, a cable may be attached to one of these headers to pick up the signal
that lights the external LED indicator. If lines for
external ID selection are not also included in the
cable, jumper plugs must be used on the header
not having a cable connected in order to establish
drive ID. The drive reads the ID from J6 and J1auxiliary for 250 ms after power-on or drive reset,
and then uses these headers for the LED function
the remainder of the time. Host system documentation should describe the application of the LED
indicator if it connects a cable to use this option.
[5] Hawk 4 family model ST15230W only.
[6] Applies to Hawk 4 family ST15230W and WD
models only.
[7] Applies to Hawk 4 family ST15230WC/DC models
only.
[8] Reserved usage. Do not install a jumper.

J2
Jumper.
Position Jumper Function Description
TE (Applies to "W" models only)
On With the jumper installed, the optional on-
board (non-removable) terminator circuits
are enabled (connected to the I/O lines).
Default is jumper installed.
Off Terminator circuits not connected to I/O lines.
DS ME
Off Off Spindle starts immediately after power up -
Default setting.
Off On Drive spindle does not start until Start Unit
command received from host.
On Off Spindle Start-up is delayed by SCSI ID times
12 seconds after power is applied, i.e., drive
0 spindle starts immediately when DC power
connected, drive 1 starts after 12 second
delay, drive 2 starts after 24 second delay,
etc.
On On Drive spindle starts when Start Unit com-
mand received from host. Delayed start feature is overridden and does not apply when
ME jumper is installed.

WP
On Entire drive is write protected.
Off Drive is not write protected. Default is no
WP jumper installed.
PE
On Parity checking and parity error reporting by
the drive is enabled. Default is PE jumper
installed.
Off Drive does not report result of parity check-
ing to host.
SS Reserved Jumper position. Do not install a
jumper.

TP TP (Not applicable to "WC and DC" model
drives)
Off Off No terminator power is connected to drive
terminators or SCSI bus I/O pin 26.
On Off Drive supplies its own terminator power
only. Jumper on this position is factory
default.
Off On Drive supplies power to I/O pin 26 of SCSI
bus; none to internal terminators. When
drives have differential I/O circuits a jumper
on the right TP position may be needed to
power external terminator (see system
documentation). The Hawk 4 family
ST15230WD drive has differential I/O circuits which have no terminator circuits on
the drive.
On On Drive supplies terminator power to itself
(internal connection) and to I/O pin 26 of
SCSI bus. This is a legal jumper setting.
TP Position A
On This horizontally positioned jumper across
the two TP positions nearest PCB edge,
connects terminator power from SCSI bus
I/O pin 26 to the drive's internal terminators (for single-ended I/O only).
Off See above explanations for TP jumpers.

J6 and J1-Auxiliary
Jumper
InstallationJumper Function Description
A3,A2,A1,A0*Drive ID on SCSI Bus. The drive ID is
binary coded positionwise i.e., jumper in
position A3 is drive ID 8, in position A2 is
drive ID 4, in position A1 is ID 2, position A
is ID 1 and no jumpers is ID 0. Default is
ID = 0.
Either J1-auxiliary or J6 may be used to
select drive ID. Both should not be used at
the same time, because at some future
time when the ID is changed the user could
fail to configure both J1-auxiliary and J6
the same. Default is ID = 0.
BUSY Connection for optional external Drive
Busy indicator.

Drive installation
This section describes the physical mounting of the
drive in the host cabinet and the logical installation as
a system member, which is called drive setup.
Disc drive mounting
Do not touch the connector pins or any PCB components without observing static-discharge precautions.
Always handle the drive by the frame only.
The drive may be mounted in any orientation.
• See notes on Figures 4 and 5 pertaining to proper
drive installation.
• Verify that all connections between the drive and the
host system are correctly installed. Most cables have
a contrasting color stripe indicating pin 1. Pin 1 on the
drive I/O, J1-auxiliary DC power connectors are
indicated in the figures in the Initial Set-up Information section.
• Verify option select and drive ID select jumpers. See
Drive Configuration section.

___________________________________________
Do not power up the host system until the drive is
mounted and the system cover is replaced.
• Connect DC power connector to the drive. (does not
apply to "WC and DC" models which have DC power
lines in the 80 pin I/O connector).
• Replace the Host System cover.
• Turn on DC power.
• Boot the system from the floppy drive or from a
previously installed hard-drive if there is one.
• Proceed with drive setup of the new hard drive.
Grounding
Signal ground (PCB) and HDA ground are connected
together in the Hawk 4 (Wide bus) drive and cannot be
separated by the user. The equipment in which the
drive is mounted is connected directly to the HDA and
PCB with no electrically isolating shock mounts. If it is
desired for the system chassis to not be connected to
the HDA/PCB ground, the systems integrator or user
must provide a nonconductive (electrically isolating)
method of mounting the drive in the host equipment.

Hawk 4 (Wide) Family Install Guide, Rev. A 37
___________________________________________
SCSI interface drives
The SCSI interface handles both drive geometry and
defect management internally. The "no drive installed"
option is selected for systems with SCSI drives.
All SCSI interface drives are low-level formatted at the
factory. You may wish to low-level format the drive to
optimize its performance for your system. Consult the
controller documentation for information on low-level
formatting. Partitioning and high-level formatting can
be done through DOS by way of the FDISK utility for
partitioning, and FORMAT for high-level formatting.
Consult your DOS manual for FORMAT and FDISK
command options.
