Preface  
This manual contains information for users of the Seagate®  
Medalist Pro SCSI disc drives. It provides support services, per-  
formance specifications, and initial setup information. Additional  
information is available in the Medalist Pro Product Manual (part  
number 32661-001). Contact your Seagate sales representative  
if you need to order this publication.  
Handling precautions  
Disc drives are fragile. Do not drop or jar the drive. Use a  
padded surface during installation to avoid damaging the  
drive.  
Keep the drive in its antistatic bag until you are ready to  
install it.  
Protect the drive from static discharge by making sure you  
are well grounded before touching the drive. We recommend  
wearing a grounded wrist strap (Seagate part number  
12263496) throughout the installation process. Do not touch  
the connectors or any part of the printed circuit board.  
Always handle the drive by its edges or frame.  
Do not apply pressure or attach labels to the circuit board or  
the top of the drive.

Electrostatic discharge protection  
Caution.  
Removal of circuit boards by personnel not perform-  
ing depot repair will damage components and may  
void the warranty.  
All drive electronic assemblies are sensitive to static electricity,  
due to the electrostatically sensitive devices used within the  
drive circuitry. Although some devices such as metal-oxide semi-  
conductors are extremely sensitive, all semiconductors, as well  
as some resistors and capacitors, may be damaged or degraded  
by exposure to static electricity.  
Electrostatic damage to electronic devices may be caused by the  
direct discharge of a charged conductor or by exposure to the  
static fields surrounding charged objects. To avoid damaging  
drive electronic assemblies, observe the following precautions  
when installing or servicing the drive:  
• Ground yourself to the drive whenever the drive electronics  
are or will be exposed. Connect yourself to ground with a wrist  
strap (Seagate part number 12263496). Connection may be  
made to any grounded metal assembly. As a general rule,  
remember that you and the drive electronics must all be  
grounded to avoid potentially damaging static discharges.  
Turn off the power before removing or installing the DC power  
cable.  
• Do not remove any circuit boards from the drive.  
• Never use an ohmmeter on any circuit boards.  
• When installing the drive on a carrier or tray, discharge the car-  
rier or tray prior to inserting it into the system.

Important safety information and precautions  
Caution.  
Use forced-air ventilation when bench-testing the  
drive to ensure proper cooling of drive components.  
Use proper safety techniques for safe, reliable operation of this  
unit.  
The procedures in this manual and labels on the unit contain  
warnings and cautions that must be carefully read and followed  
to minimize or eliminate the risk of personal injury. The warnings  
point out conditions or practices that may endanger you or oth-  
ers. The cautions point out conditions or practices that may dam-  
age the unit, possibly making it unsafe for use.  
Always observe the following warnings and precautions:  
• Follow all cautions and warnings in the procedures.  
• Use sound safety practices when operating, installing, or  
removing the unit.  
• Use caution when troubleshooting a unit that has voltages  
present. Turn off power to the unit before removing it.  
• Ensure that the internal temperature of the rack or cabinet  
does not exceed the limits defined for the drive when the drive  
is mounted in an equipment rack or cabinet. When units are  
stacked vertically, pay special attention to the top where tem-  
peratures are usually highest.  
• Follow the precautions listed above in “Electrostatic discharge  
protection.”  
• Do not remove any circuit boards from the drive. Return the  
entire drive for depot repair if any circuit board is defective.  
Removal of circuit boards by personnel not performing depot  
repair will damage components and may void the warranty.

Medalist Pro Installation Guide, Rev. B  
• Do not remove the head and disc assembly (HDA) from the  
drive. Return the entire drive for depot repair if the HDA is  
defective.  
• Do not attempt to disassemble the HDA. It is not field repair-  
able. If the sealed HDA is opened by personnel not performing  
depot repair, this will damage components and void the  
warranty.  
As a component, this drive is designed to be installed and oper-  
ated in accordance with UL1950, EN60950, CSA C22.2 950-  
M89, and VDE0805.  
Seagate takes all reasonable steps to ensure that its products  
are certifiable to currently accepted standards. Typical applica-  
tions of these disc drives include customer packaging and sub-  
system design. Safety agencies conditionally certify component  
assemblies, such as the Medalist disc drive, based on their final  
acceptability in the end-use product. The subsystem designers  
are responsible for meeting these conditions of acceptability in  
obtaining safety-regulatory agency compliance in their end-use  
products and for certifying where required by law. A necessary  
part of meeting safety requirements is the provision for overcur-  
rent protection on drive SELV supply voltages.  
This unit is a component part and as such is not meant to com-  
ply with FCC or similar national requirements as a stand-alone  
unit. Engineering radiated emissions test results are available  
through the Seagate Safety Department to assist the subsystem  
designer.

Entfernung der Einheit angemessene Sicherheitsvorkehrun-  
gen.  
• Wenn eine Einheit unter Spannung steht, gehen Sie bei der  
Fehlerdiagnose besonders vorsichtig vor. Schalten Sie die  
Einheit aus, bevor Sie mit den Installations-und Entfernungsar-  
beiten beginnen.  
• Wenn das Laufwerk in einem Einbaugestell oder Gehäuse  
montiert ist, sorgen Sie dafür, daß die Temperatur im Inneren  
des Gestells oder Gehäuses die für das Laufwerk vorgege-  
benen Grenzwerte nicht übersteigt. Wenn Einheiten vertikal  
übereinander betestigt werden, achten Sie besonders auf den  
oberen Stapelbereich, da dort die Temperatur gewöhnlich am  
höchsten ist.  
• Befolgen Sie die oben unter “Electrostatic Discharge Protec-  
tion” angegebenen Sicherheitsmaßnahmen.  
• Nehmen Sie keine Platinen aus dem Laufwerk. Wenn eine  
Platine defekt ist, muß das gesamte Laufwerk zur Reparatur  
eingeschickt werden. Die Herausnahme von Platinen durch

As a component assembly, the drive is not required to meet any  
susceptibility performance requirements. It is the responsibility of  
those integrating the drive within their systems to perform those  
tests required and design their system to ensure that equipment  
operating in the same system as the drive or external to the sys-  
tem does not adversely affect the performance of the drive. See  
Table 2a, DC power requirements.  
Electromagnetic compliance  
Seagate uses an independent laboratory to confirm compliance  
to the directives/standard(s) for CE Marking and C-Tick Marking.  
The drive was tested in a representative system for typical appli-  
cations. The selected system represents the most popular char-  
acteristics for test platforms. The system configurations include:  
• 486, Pentium, and PowerPC microprocessors  
• 3.5-inch floppy disc drive  
• Keyboard  
• Monitor/display  
• Printer  
• External modem  
• Mouse  
Although the test system with this Seagate model complies to  
the directives/standard(s), we cannot guarantee that all systems  
will comply. The computer manufacturer or system integrator  
shall confirm EMC compliance and provide CE Marking and C-  
Tick Marking for their product.

General description  
Medalist Pro SCSI disc drives are high-speed, random-access  
digital-data storage devices.  
The drive is a component for installation in an enclosure  
designed for the drive. This is often a rack within the system or  
an external enclosure designed to house one or more disc drives  
or other peripheral units. In either case, the disc drive must  
receive adequate cooling (refer to “Providing adequate cooling”)  
and it must be sufficiently grounded and shielded from emis-  
sions. The Medalist Pro Product Manual (part number 32661-  
001) contains guidelines for a properly designed enclosure.

Medalist Pro Installation Guide, Rev. B  
±5% must be maintained after the drive signifies that its  
power-up sequence has been completed and that the drive is  
able to accept selection by the host initiator.  
[3] See the +12V current profile in the Medalist Pro Product  
Manual (publication number 32661-001).  
[4] This condition occurs when the Motor Start option is enabled  
and the drive has not yet received a Start Motor command.  
[5] See “Conducted noise immunity” in the Medalist Pro Product  
Manual. The specified voltage tolerance is inclusive of ripple,  
noise, and transient response.  
[6] Operating condition is defined as random seek read opera-  
tions with a block count of 64.  
General Notes for Tables 2a and 2b:  
1. Minimum current loading for each supply voltage is not less  
than 4% of the maximum operating current shown.  
2. Use separate ground returns for +5V and +12V supplies.  
3. Where power is provided to multiple drives from a common  
supply, carefully consider individual drive power require-  
ments. Where multiple units are powered on simultaneously,  
be sure the peak starting current is available to each device.

drives. To mount “WC” or “LC” drives, plug the drive into the  
system’s single connector attachment (SCA) position on the  
system’s back panel.

SCSI ID jumpers  
Each device on the SCSI chain must have a unique SCSI ID.  
The host system’s SCSI controller usually uses the ID that has  
the highest priority in the SCSI I/O system. This is always ID7.  
ID0 is lowest priority in an 8-bit I/O system. ID8 is lowest priority  
in a 16-bit I/O system. The lower priority SCSI IDs are normally  
used for other SCSI devices such as this Medalist disc drive.  
Note.  
Most SCSI controllers (host adapters) allow you to skip a  
SCSI ID. For example, you can have ID0, ID1, and ID3  
(skipping ID2). Other controllers do not allow this so be  
sure to refer to your system or controller user’s manual  
for details about its requirements for proper SCSI device  
installation.  
Note.  
This drive is a SCAM (SCSI Configured Auto Magically)  
compliant drive. If the system into which you are installing  
this drive requires SCAM compliant drives, you do not  
need to be concerned about the drive ID jumper settings,  
as the system automatically assigns your new drive the  
ID it wants it to have. The system may or may not use the  
existing drive ID jumper settings. Setting the drive ID  
doesn’t hurt anything, but is not necessary in a SCAM  
compliant system.  
The Medalist disc drives are factory set with the SCSI ID set at 0.  
To change the SCSI ID, refer to the appropriate drive section for  
your model.  
If, after completing the installation process, the drive’s LED does  
not show on/off activity when the host is trying to communicate  
with the drive, a duplicate SCSI ID may be the problem. If this is  
the case, change the ID so that each device on the SCSI chain  
 
24  
Medalist Pro Installation Guide, Rev. B  
has its own unique ID. Also check your system or controller  
user’s manual to ensure that you have not violated its SCSI ID  
numbering recommendations.  
Drive termination  
If you are installing a Medalist drive in a system that has other  
SCSI devices installed, terminate only the end devices on the  
SCSI chain. A SCSI “device” is any disc drive, scanner, tape  
backup unit, or other piece of hardware connected to your sys-  
tem using the SCSI bus.  
The top example in Figure 2 shows an internal hard disc at one  
end of the SCSI bus with the SCSI controller at the other end  
(both are terminated). The bottom example shows two additional  
SCSI devices connected externally—this means the SCSI con-  
troller is no longer on the end of the SCSI chain and should not  
be terminated.  
Note.  
Some controllers prefer to remain terminated even if they  
are in the middle of the chain. Also, some controllers treat  
the internal and external chains as separate logical  
buses. This means you may need to terminate both the  
first and last devices on both logical buses to achieve  
proper termination. If necessary, refer to your system or  
controller documentation to see how this is handled in  
your particular system.  
 
Medalist Pro Installation Guide, Rev. B

You usually will not need to change this option and can normally

information about how to change the terminator power option on  
your drive, refer to the appropriate drive-specific section.  
I/O circuits and data path widths  
“W,” “WC,” “LW,” and “LC” models have a “wide” (16-bit) SCSI  
data bus rather than the standard (non-wide) 8-bit SCSI data  
bus; however, you can use these wide drives on a standard (non-  
wide) 8-bit data bus using a terminated 68-pin to 50-pin SCSI  
cable (not applicable to “WC” or “LC” drives which are not to be  
connected into the system via cable).

Providing adequate cooling  
The enclosure design must ensure adequate cooling for the  
drive. The maximum ambient temperature is 50°C.  
The drive’s product manual (32661-001) describes how to evalu-  
ate the air-flow design. The evaluation consists of ensuring that  
the case temperature of certain critical components remains  
within acceptable limits during drive operation.  
We recommend orienting the drive or directing the air flow in a  
way that creates the least amount of air-flow resistance while  
providing air flow above the circuit boards and around the head  
and disc assembly (HDA). Also, choose the shortest possible  
path between the air inlet and exit. This minimizes the distance  
traveled by air that is heated by the drive and by other nearby  
heat sources.  
Figure 4 shows two design approaches with one or more fans  
used to generate air flow. The air-flow patterns can be created  
by the fans either pushing or drawing air. The overall flow pattern  
can be directed from front to back, back to front, or side to side.

Kühlung des Systems  
Die Gehäusekonstruktion muß eine ausreichende Kühlung des  
Laufwerkes gewährleisten. Die Umgebungstemperatur darf max-  
imal 50°C betragen.  
Die Produkthandbuch Medalist Pro (Dokument 32661-001)  
enthalten Anweisungen zur Beurteilung der Luftstromkonstruk-  
tion. Die Beurteilung muß sicherstellen, daß sich die Gehäuse-  
temperatur bestimmter kritischer Komponenten bei  
Laufwerkbetrieb innerhalb zugelassener Grenzen hält.  
Wir empfehlen, das Laufwerk so zu orientieren oder den Luft-  
strom so zu lenken, daß der geringste Luftstromwiderstand  
erzeugt wird und gleichzeitig ein Luftstrom über den Platinen  
und um die Kopf- und Festplatteneinheit (HDA) gegeben ist.  
Wählen Sie einen möglichst kurzen Weg zwischen Lufteinlaß  
und -auslaß. Dadurch wird die Strecke, die die vom Laufwerk  
und anderen nahegelegenen Hitzequellen aufgewärmte Luft  
zurücklegt, auf ein Minimum beschränkt.  
Abbildung 4 zeigt zwei Konstruktionsmöglichkeiten, bei denen  
ein oder mehrere Lüfter den Luftstrom erzeugen. Der Luftstrom-  
verlauf wird durch die Lüfter gesteuert, die entweder Luft einbla-  
sen oder abziehen. Generell kann der Luftstrom entweder von  
vorne nach hinten oder von hinten nach vorne verlaufen.

Mounting the drive and connecting cables  
Do not touch the connector pins or any components on the con-  
trol board without observing static-discharge precautions.  
Always handle the drive by the frame only.  
The drive may be mounted in any orientation (horizontally, verti-  
cally, and any combination thereof); however, you must ensure  
that the drive receives adequate air flow for cooling.  
1. Mount the drive to the host system’s chassis using four 6-32  
UNC screws. Two mounting holes are in each side of the  
drive and there are four mounting holes in the bottom of the  
drive.  
The maximum length that the screws should extend into the  
chassis mounting holes is 0.15 inch (3.81 mm), measured  
from the outer surface of the chassis. Tighten the screws  
down evenly. Do not over-tighten or force the screw if it does  
not seem to screw in easily, because this means the threads  
are not properly aligned. In this case, back the screw out  
and try again.  
Installation des Laufwerkes  
und Anschluß der Kabel  
Beachten Sie beim Handhaben und Anfassen der Anschlußstifte  
und Komponenten die Vorsichtsmaßnahmen zur Verhinderung  
statischer Aufladung. Fassen Sie das Laufwerk nur am Rahmen  
an.  
Das Laufwerk kann in beliebiger Orientierung (horizontal, ver-  
tikal oder schräg) installiert werden; jedoch muß dafür gesorgt  
werden, daß ein ausreichender Luftstrom zur Kühlung des Lauf-  
werkes vorhanden ist.  
 
 
36  
Medalist Pro Installation Guide, Rev. B  
1. Befestigen Sie das Laufwerk mit vier 6-32-UNC-Schrauben  
am Gehäuse des Host-Systems. Die beiden Seiten des  
Laufwerkes sind mit jeweils zwei Befestigungslöchern  
versehen, die Unterseite des Laufwerkes weist vier weitere  
Befestigungslöcher auf.  
Gemessen von der Außenfläche des Gehäuses dürfen die  
Schrauben maximal 3,81 mm in die Befestigungslöcher des  
Gehüuses hineinragen. Die Schrauben müssen gleich-  
mäßig, jedoch nicht zu fest, angezogen werden. Wenn sich  
eine Schraube nicht ohne Widerstand einschrauben läßt,  
sind die Gewinde nicht korrekt aneinander ausgerichtet. In  
diesem Fall die Schraube nicht in das Gewindeloch  
forcieren, sondern die Schraube herausnehmen und erneut  
in das Gewindeloch einführen.  
2. Verify that all connections between the drive and the host  
system are correctly installed.  
2. Prüfen Sie, ob alle Verbindungen zwischen dem Laufwerk  
und dem Host-System korrekt hergestellt sind.  
3. Verify that you have correctly installed jumpers.  
3. Stellen Sie sicher, daß die Kennungsbrücken installiert sind.  
4. Connect the SCSI cable into the drive’s SCSI connector.  
Take care not to stretch or crimp this cable, and do not block  
the system’s cooling air flow with the cable.  
The drive receives DC power through a 4-pin connector  
mounted next to the SCSI connector. The output of a power  
supply must meet SELV (safety extra low voltage) as  
 
Medalist Pro Installation Guide, Rev. B  
37  
defined in IEC 950. Figure 5 provides the pin information for  
the DC power connector. To connect the DC power cable to  
the drive, simply insert the cable end into the drive’s DC  
power connector.  
4. Schließen Sie das SCSI-Kabel an den SCSI-Steckverbinder  
des Laufwerkes an. Das Kabel darf nicht gedehnt oder  
gedrückt werden und es darf den Luftstrom zur Kühlung des  
Systems nicht behindern.  
Das Laufwerk wird über einen 4-poligen, neben dem SCSI-  
Anschluß befestigten Steckverbinder mit Gleichstrom ver-  
sorgt. Der Ausgang eines Netzteils muß SELV (safety extra  
low voltage) nach IEC 950 entsprechen. Abbildung 5 zeigt  
die Steckerbelegung für den Gleichstromanschluß. Zum  
Anschluß des Gleichstromkabels an das Laufwerk das  
Kabelende in den Gleichstromanschluß des Laufwerkes  
stecken.

Note. Signal ground on the power control board (PCB) and the  
head and disc assembly (HDA) are connected together in  
this drive and you cannot separate them. The equipment  
in which you have mounted the drive is connected  
directly to the HDA and PCB without electrically isolating  
shock mounts. Maximizing the conductive contact area  
between HDA ground and system ground may reduce  
radiated emissions.  
If you do not want the system chassis to be connected to  
the HDA/PCB ground, you must provide a nonconductive  
(electrically isolating) method of mounting the drive in the  
host system. This may increase radiated emissions and  
is the system designer’s responsibility.  
Hinweis:  
Die Signalerde auf der Stromregelungskarte (PCB) und  
der Kopf- und Festplatteneinheit (HDA) sind in diesem  
Laufwerk miteinander verbunden und können nicht  
getrennt werden. Das Gerät, in das Sie das Laufwerk  
eingebaut haben, ist ohne elektrisch isolierende  
Stoßdämpfer direkt an die HDA und PCB angeschlossen.  
Die elektromagnetische Strahlung kann reduziert wer-  
den, indem Sie eine möglichst große leitende Kontak-  
fläche zwischen der HDA-Erdung und der Systemerdung  
vorsehen.  
Wenn Sie das Systemgehäuse nicht an die HDA/PCB-  
Erdung anschließen wollen, müssen Sie das Laufwerk  
auf nichtleitende Weise (galvanisch isoliert) im Host-Sys-

Formatting the drive  
Warning.  
Formatting a drive erases all user data. Be sure that  
you understand this principle before formatting any  
hard disc drive. It is not necessary to format a drive  
that previously has been used to store data, unless  
your intention is to erase all user data.  
Note.  
Seagate is not responsible for lost user data.  
1. Turn on DC power.  
2. Boot the system from a system floppy disc or from a previ-  
ously installed hard disc drive if there is one.  
3. Format the disc drive. Medalist Pro disc drives are designed  
to operate with a variety of operating systems. Please refer  
to your system or SCSI controller manual for information  
about formatting and setting up the drive. Some quick desk-  
top system notes are provided below.  
Quick reference desktop system notes  
Note.  
Refer to your system or utility manual for detailed instruc-  
tions)  
• DOS. Set the drive type in CMOS to “Zero,” “None,” or “No  
hard drive installed.” Use FDISK.EXE and FORMAT.EXE. Sys-  
tems that have operating system Windows 95 release 950B or  
later do not need to partition the drive.  
• Macintosh. Use a third-party drive utility (Apple’s HD Setup  
utility only works with drives having special Apple firmware).

on the end of the SCSI bus, disable the terminators by removing  
“TE”  
the jumper  
from pins 15 and 16 of connector J2 (see Fig-

W drives  
Terminating the drive  
“W” model drives are terminated with permanently mounted IC  
active terminators. If you install one of these drives and it is not  
on the end of the SCSI bus, disable the terminators by removing  
“TE”  
the jumper  
from pins 15 and 16 of connector J2. If you  
install the drive on the end of the SCSI bus, enable termination  
by installing a jumper on pins 15 and 16 of connector J2 (see  
Figure 13).  
Note.  
Use active (ANSI SCSI-2 Alternative 2) terminators when  
terminating the bus.

WC/LC drives  
Setting the SCSI ID jumpers  
The SCSI ID for “WC” and “LC” model drives is normally set over  
the SCSI bus by the host system using connector contacts 39  
(ID0), 40 (ID2), 79 (ID1), and 80 (ID3). Users need not install  
jumpers to select SCSI ID.  
Terminating the drive  
“WC” and “LC” model drives do not have internal terminators or  
any other way of adding internal termination to the drive. Exter-  
nal termination for these drives is normally supplied by the host  
equipment when termination is required.
