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
thedrivefeaturesareappropriatetoenableforinstal-
lation 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 in-
stalled 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.
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
boundariesandtrackinformationtothedrive).Defect
managementinformationisreadfromthedrivebythe
host system when required in the installation proce-
dure. If an installed drive is low-level formatted, all
user data stored on the drive will be lost.
Note. SeagateTechnologyassumes noliability for
lost user data.
• Partitioningandhighlevelformatting:A drivecan
be sub-divided into "partitions" which behave as
individual drives within the system. See your system
documentation. Present day drive installation pro-
grams 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
problemsoccurduringinstallation,pleasecontactyour
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 ob-
serve the following cautions.
Caution.
• Handle drive with care. Do not drop or bump hard.
• Never remove the cover of these disc drives. Serv-
icing items in the sealed HDA (heads, media, actua-
tor, etc.) require special facilities. The drive contains
no user purchasable parts or PCBs.
• Opening the sealed HDA voids the drive warranty.
• Applyingasolderingdevicetothecomponentsonthe

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"WCandDC"modelsplugdirectly
intoaPCBorbulkheadmountedmating80pinconnec-
tor. 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 recom-
mended at the cable for drives using cables. Do not
block system cooling air flow in routing of cables.
DC Power connection
ModelST15230W/WDfamilydrivesreceiveDCpower
through a 4 pin connector mounted on the PCB next to
the SCSI I/O connector. See Figure 1.

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
SCSIbusaddressjumperplugsareproperlysetforthe
bus address assigned to the drive. In some systems, a
cableplugsintoeitherJ6orJ1auxiliary, sodriveIDcan
besetatsomeremotelocation. SeeFigures3aand3b
showingthebusaddressselectheaderandthejumper
configurationsthatselectaddresses0through15. ID7
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
verylowestpriority.Typicallytheprimarybootdeviceis
set to ID 0 the host is ID 7, and the subsequent SCSI
drives are jumpered as appropriate for the particular
system involved.
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
hostsystemalsohascompletecontrolovermotorstart
functions, so no Motor Start or Delayed Motor Start
Jumpers should be installed.
Terminator resistor packs
ModelST15230WfamilydriveshaveI/Olineterminator
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
installingmultipleharddiscdrives,disablethetermina-
tion resistors from all the drives but the one connected
to the end of the SCSI I/O cable.

Hawk 4 (Wide) Family Install Guide, Rev. A
___________________________________________
Modelnumbersthatendin"WDandDC"havedifferen-
tialI/Ocircuitsandthesedrivesand"WC"modeldrives
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
Seagatediscdrivesdescribedhereinmentionedinthis
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.

figures show where these headers are located on the
different drives covered by this manual. See notes

Notes for Figure 3a, 3b and 3c:
[1] Notesexplainingthefunctionsofthevariousjump-
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 Onunder-
lined 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 in-
stead 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
selectfunctions,andtheremoteLEDsignal.Donot
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
plugsinoneofthepatternsshowninFigures3a,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 func-
tions of these two headers that are time-shared
with the drive ID function.

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 at-
tachedtooneoftheseheaderstopickupthe 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 J1-
auxiliary 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 documen-
tation should describe the application of the LED
indicator if it connects a cable to use this option.

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 compo-
nents 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
hostsystemarecorrectlyinstalled.Mostcableshave

___________________________________________
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

___________________________________________
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.
