The drive(s) described herein, as delivered, are de-
signed for system integration and installation into a
suitable enclosure prior to use. As such, the drive(s)
described herein are supplied as a sub-assembly and
arenotsubjecttoSubpartJofPart15oftheFCCRules
and Regulations nor the Radio Interference Regula-
tionsoftheCanadianDepartmentofCommunications.

The physical design characteristics of the drive(s)
described herein, serve to minimize EMI radiation
when installed in an enclosure that provides reason-
able shielding. As such, the drive(s) are capable of
meeting the Class B limits of the FCC Rules and the
RegulationsoftheCanadianDepartmentofCommuni-
cations.
Note. It is the end users' responsibility to assure that
the drive(s)describedhereinmeettheappropri-
ateEMIrequirementsoftheirsystem.ShieldedI/
O cables may be required if the enclosure does
notprovideadequateshielding.IfI/Ocables are
externaltotheenclosure,shieldedcablesshould
beused, with theshields groundedtothe enclo-
sure and to the host controller.

Before you begin
Verify that the system is switched off and discon-
nected from main power before any installation is
attempted.
Protect yourself, the drive, and your valuable pro-
grams and data by reading the following cautions
and warnings.
• Donotunpackdrivefrom itsstatic shieldedbaguntil
you are ready to install it in the system.
• Always handle the drive by the frame or casting.
• Do not touch printed circuit board (PCB) or the I/O
connector pins.
• Never apply pressure to the PCB or to the drive top
cover.
• Donottamperwithsealed topcover. Doingsovoids
your warranty. The drive contains no user service-
able components. See Product Repair section for
moreinformation.
• Visually inspect the shipping container for any obvi-
ous damage.

• Verifyallpartslistedonshippingbillarereceivedwith
the equipment. Discrepancies or damage should be
reported to the shipping company.
• When transporting or shipping a drive or system,
please ensure that they are correctly packed in
original Seagate approved (or equivalent) container
and shipped via an air-ride carrier experienced in
handling computer equipment.
Caution. The circuit assemblies and components
contained in this equipment can be de-
graded or destroyed by Electrostatic Over-
stress (EOS) or by Electrostatic Discharge
(ESD).
Static electrical charges can accumulate
quicklyonpersonnel,clothingand synthetic
materials. The electrostatic fields due to
these charges when brought in close prox-
imity to susceptible circuit assemblies and
components,canresultindegradedreliabil-
ity or immediate failure of the affected com-
ponent or assembly.

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.
•Driveconfiguration:Theusermustselectwhichof
thedrivefeaturesareappropriatetoenableforinstal-
lationintheirsystem.Thisisdonebywayoftheuser
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 precau-
tions 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 2 (Wide bus) Family Install Guide, Rev. C
•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

grams have menus that lead you through these
installationprocedures.

Service requirements
The special facilities required for the manufacture of
these drives generally prohibit repair in the field. If
problemsoccurduringinstallation,pleasecontactyour
supplierforassistance.Donotattempttodisassemble
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-
icingitems in the sealedHDA (heads, media, actua-
tor,etc.)requirespecialfacilities. Thedrive contains
no user purchasable parts or PCBs.
• Opening the sealed HDA voids the drive warranty.
• Applyingasolderingdevicetothecomponentsonthe
PCB voids the drive 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 or WD. These
procedures are described in paragraphs following.
SCSI interface cable connection
Thedrivescovered by this manual areSCSI interface
drives.For"W"and"WD"" models,systemconnection
is via a 68 pin, SCSI connector. For "WC" models
system connection is via an 80 pin SCSI connector.
Normally "WC" models plug directly into a PCB or
bulkhead mounted mating 80 pin connector. Pin 1 is
noted in Figures 1a and 1b. Some cables have a
contrasting color stripe on one edge to indicate pin 1.
TheI/Oconnectoriskeyedbyvirtueofitsshape.There
is only one way it can mate with the mating input
connector.Strainreliefisrecommendedatthecablefor
drives using cables. Do not block system cooling air
flow in routing of cables.
DC Power connection
