Configuring the drive
Required materials:
2-mm jumper connector (supplied as spare jumpers)
Your Seagate drive is configured for operation using the options
jumper block (J8) shown in Figure 1 on page 6. The settings for
theavailableconfigurations areshowninFigure2onpage7.The
options jumper block (J8) allows you to:
•Set the SCSI ID
•Connect a remote LED
•Enable or disable parity
•Enable or disable the drive’s terminator
•Select the termination power source
SCSI ID settings. Each device on the SCSI bus must be as-
signed a unique SCSI ID. The drive uses pin-pairs1 and 2, 3 and
4, and 5 and 6 on the options jumperblock (J8) forassigning the
ID. The chart in Figure 2 shows you how to place the jumpers to

assign ID values0 through 7. Be sure that the ID you choose is
not used by another device on the SCSI bus.
YourSeagate driveis shippedby the factory configuredas SCSI
ID 3—jumpers are attached to pins 3 and 4 and pin 5 and 6. You
must reconfigure the SCSIID if another device is assigned SCSI
ID 3 or if you are making the drive the bootable drive. The
bootable drive must be Drive C. It must be assigned the ID
number your SCSIadapterrecognizes as the first positionon the
bus. Usually, this is SCSI ID 0 (refer to your SCSI host adapter
documentation).
If installing your new drive puts more than two drives on the bus,
your SCSI adapter may require thatyou install a device driver or
that you reconfigure its onboard BIOS. Refer to your SCSI
adapter’s user guide for instructions on how to install the third
drive.If a device driver isrequired, it will beprovided bythe SCSI
adapter manufacturer.
Remote LED. You can connect a remote LED to the drive using
pins 9 and 10 on jumper block J8. Connect the LED ground wire
(usually the black wire) to pin 9.
Remote start. This setting causes the drive to wait for a specific
commandfromthehostbeforeitstartsorstopsthespindlemotor.
Parityenable.Parityisamethodthatissometimesusedforerror
detection. The drive is shippedwith parity enabled.
Terminators. The drive is designed with single-ended drivers
andreceiversandmustbeusedwithotherSCSIdevicesthatuse
single-ended drivers and receivers. These systems require that
terminators be used at both ends of the SCSI bus to ensure the
integrity of the signal. The drive has built-in terminators that can
be enabled or disabled as required. It is shipped with the termi-
8 Medalist 1080sl SCSI Installation Guide, August 1995

nators enabled. If you are positioningthe drive at the end of the
cable, you must enable the drive’s internal terminators or attach
an external terminator to the endof the cable.Terminatorson the
devices between the bus ends must be disabled or removed.
•Toenablethedrive’sterminators, leavethepin-pair19 and20
on jumper block J8 open.
•To disable the terminators, place a jumper on pins 19 and 20
of jumper block J8.
Terminator power. The terminators must have a 5 volt power
source to be active. In general, the device that provides the
terminator also provides power for its terminator. Power for the
terminator may also be supplied through the SCSI cable (this is
usually done for external terminators). The Seagate drive pro-
vides settings for four implementations of terminator power:
•Terminator power to the drive terminator and the SCSI bus—
install jumpers on pins 21 and23 andon pins22 and 24of J8.
This is the default.
•Terminator power to the drive terminators only—install a
jumper on pins 23 and 24 of J8.
•Terminator power from another device to the bus and the
drive’s terminator disabled—install a jumper on pins 21 and
23 of J8.
•Terminator power to the bus only and the drive terminator
disabled—install a jumper on pins 22 and 24 of J8.
Medalist 1080sl SCSI Installation Guide, August 1995 9

Attaching cables
Required materials:
A four-conductor power-supply cable
A fifty-conductor, nonshielded interface cable with a 50-pin, fe-
male connector attached for each SCSI device that is to be
connected to the SCSI bus. The maximum cable length for
asynchronous operation is 19.5 feet (6 meters). The maximum
cable length for synchronous operation is 9.75 feet (3 meters).
Figure 1 on page 6 shows connectorand jumper block locations.
1. Turn off the system power and put on a grounded wrist
strap before proceeding.
2. Attach the 50-pin SCSI interface cable. Pin 1 on the drive
mustalignwithpin1oftheotherSCSIdevicesattachedtothe
bus. Use the edge-stripe on the cable to denote pin 1. Pin 1
on the drive is located next to the four-pin power connector.
2. ConnectingaremoteLED.(Optional)ConnectaremoteLED
to pins 9 and 10 of jumper block J8. Pin 9 is ground.
3. Attach an available power cable to the drive.

Configuring the drive and computer
Once the drive is physically installed, the drive and computer
must be configured to work with each other. This involves parti-
tioning and formatting thedrive and may require aspecial device
driveror installation softwaredependingonthe operating system
you are using and your SCSI adapter. Refer to your SCSI
adapter’s documentation for specific information on how to con-
figure your drive.
This guide describes a typicalconfiguration for a PC using DOS
and one or two SCSIdrives only.
System setup configuration
Required materials:
•A bootable diskette with the Format and FDISK command
IfyouarereplacingtheATA(IDE)driveordrivesinyourcomputer
with SCSI, you must reset the drive-type configuration listed in
System Setup to
Not Installed .
1. Turn the computer on.
2. Enter the System Setup routine. (Refer to your computer’s
user guide. System Setup may be called Setup, BIOS Setup
or CMOS Setup.)
3. Find the hard disc configuration in the System Setup screen.
4. Change the drive-type status to
Not Installed .
5. Save the changes and exit System Setup.
Low-level formatting
Yourdrive was low-level formatted atthefactory to512 bytes per
sector.Youdonot needtolow-levelformatitagain.Ifyouchoose
12 Medalist 1080sl SCSI Installation Guide, August 1995

to low-level formatthe drive, usethe format routine supplied with
your SCSI adapter. Refer to the SCSI adapter’s documentation
for instructions on how to low-level format the drive.
Partitioning
Youmustpartitionthedriveintooneormorelogical drivesbefore
you can use it.
Caution. Partitioningor formatting a drive atany level erases all
dataon it. Make a backup copy ofyour existingfiles on
another drive before you repartition or reformat. Sea-
gate assumes no liability if you erase your data.
To partition the drive:
1. Insert a bootable diskette into Drive A. Turn the computeron.
2. After the computer has completed booting, remove the boot
diskette from Drive A. Insert a diskette that has the FDISK
utility into Drive A and type fdisk. Press ENTER.
Note. Ifyouhavetwoormoredrives inyoursystem,themenu
displays five options. Option five allows you to select
thedriveyouwanttopartition. Makesure youselectthe
correct drive.
3. Select
createDOSpartitionorlogicalDOSdrive .PressENTER.
4. Select
create primary DOS partition . Use the maximum avail-
able size for your primary partition and make the partition
active for Drive C. This puts the entire drive on one partition
andallows you toload the DOSboot informationon thedrive.
Press ENTER for each subsequent selection.
After all of the appropriate selections are made, the computer
restarts itself. You must place a bootable diskette into Drive A.
Medalist 1080sl SCSI Installation Guide, August 1995 13

High-level formatting
High-level formatting verifies the information written by the low-
levelformatandbuildsthefileallocationtable(FAT)usedbyDOS
to access files on the drive. If you put more than onepartition on
thedrive, you must high-level format each partition.Referto your
DOS reference guide for instructions. Use the DOS FORMAT
utility to high-level format the drive as follows:
1. Type the followingcommand at the DOS prompt:
format
drive: /v /s
drive : designates the drive you are formatting. If you are
formatting the boot drive or if your system contains only one
drive, type c:.To format a second drive, type d:.
/v tellsthe computer to create a volume label for the partition
after it is formatted. Labeling can prevent someone from
accidentally deleting the partition and losing your data.
/s tells thecomputer to copy the necessary systemfiles to the
drive to make it bootable.
2. When the computer prompts you for a volume label, you can
assign a name to the drive volume of up to eleven characters
or leave it blank. Press ENTER.
14 Medalist 1080sl SCSI Installation Guide, August 1995

NonDOS operating systems
Ifyouareinstallingthedriveinasystemthatisusinganoperating
system other than DOS, you may need a device driver or instal-
lation software. The device driver is provided by your SCSI
adapter manufacturer and is operating-system specific. It is pro-
videdonadiskettethatcomeswiththeadapter.RefertotheSCSI
adapter’s documentation for instructions on how to install the
device driver. If you do not have a device driverfor the operating
system you want to install, contact the SCSI adapter manufac-
turer.
Installation software may be required to install the drive in some
systems. There are many reputable third-party installation soft-
ware packages available. Consult your dealer to determine the
best package for your needs.
Some operating systems require that you low-level format the
drive. A low-level format routine is usually supplied on the SCSI
adapter. Refer to your SCSI adapter’s documentation for instruc-
tions on using the low-level format routine.
Network installation
If you are installing the drive in a network environment, you may
need to configure your SCSI host adapter for network operation.
Refer to your SCSIadapter’s userguide forassistance preparing
the SCSI adapter and installing the drive.
If youhave trouble installing the drive with the network software,
try installing it with DOS to ensure that the drive is working
correctly.
Medalist 1080sl SCSI Installation Guide, August 1995 15

Basic troubleshooting
Warning. Alwaysturnoff thesystembefore changingjumpers or
unplugging cables and cards.
If yourdrive does notrespond or function properly whenyouturn
the power on following the hardware installation, perform these
basic checks:
•Check all cards. Make sure all cards are seated securely in
their slots on the motherboard.
•Check all cables. Make sure all cables are securely con-
nected. Adamaged ribboncableor connector strainrelief can
cause the SCSIbus to fail.
Verify that the pins 1 of eachdeviceon the cable are aligned.
Use the edge-stripe on the cable to denote pin 1.
Caution. Improperly aligning or reverse-plugging pin 1of one
device with the other devices on the cable can
damage that device or other devices.
•Check the SCSI ID. Make sure the drive’s SCSI ID does not
conflict with that of another device.
•Check theterminatorconfiguration. Ifthedriveisattheend
of the bus and external termination is not used, the drive’s
terminatormustbeenabled.Disableorremoveterminationon
all devices between the drive and thedevice at the other end
of the bus.
If the drive is not the last device on the bus or if external
terminationisused,besuretoremovethejumperthatenables
the drive’s termination.
16 Medalist 1080sl SCSI Installation Guide, August 1995

Make sure that the drive is running. Listen carefully for the
drivemotorspinning.Also,thedrive-activityLEDflasheswhen
the power is turned on. If the LED stays on after power-on,
make sure the interface cable is properly connected and that
no other device on the bus is using the same SCSI ID.
•Verify your host adapter configuration. Make sure the
address configurations your host adapter is using do not
conflict with the addresses other devices in your system use.
Refer to your host adapter’s user guide for assistance. Many
host adapters have a diagnostic utility that can help you
determine whether such conflicts exist.
Verify that the drive works when your host adapter is set with
the factory-default configuration. Refer to your host adapter’s
user guide for assistance determining the factory-default set-
tings.
•Check the CMOS drive type. If you have an AT system, the
CMOSdrive-typeparameter valuesmust be settozeroor
Not
Installed
in AT systems.
•Check the power supply specifications. The output of your
power supply may not meet the requirements of the new
devices you are installing. If you are not sure whether your
power supply meets your needs, consult your dealer.
•Check for viruses.
Before you load new software, scan the
diskette for viruses.
•Isolate the drive. If there is more than one drive in your
system, configure and install the drive for single drive opera-
tion. If you are installing the drive in a network, verify that the
drive works with DOS.
Medalist 1080sl SCSI Installation Guide, August 1995 17

Advanced troubleshooting
If you have performed the preceding basic checks but the prob-
lem has not been solved, follow these guidelines for analyzing
specific cases:
The system does not recognize the presence of the drive or
system error message, “No Drives Found,” appears.
•Check all cables. Make sure they are properly connected and
thatthepins1 are aligned.Makesurethecableis notcrimped
or damaged.
•Check all cards for proper seating.
•Check your host adapter’s BIOS memory address setting.
Makesurethatitdoesnotconflictwithanotherdevicethatsets
a BIOS memory address.
•Check the drive type in AT systems. The drive type must be
set to Not Installed or all of the drive-type parameters set to
zero.
•Check theDriveCpartitionwiththeFDISKutility.Thepartition
must be active.
•Check the bus termination. The bus must be terminated at
both ends. Disable or remove all terminators between the
termination at the ends of the bus.
•Check the terminator power source jumper settings.
•Check the power-supply specifications.
•Reboot and make sure the drive comes up to rotating speed.
(It may be difficult to hear the discs spin.) If the drive’s disc
does not spin, check all drive cables.
