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
the available configurations are shown in Figure 2 on page 7. 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 assigned a unique SCSI ID. The drive uses pin-pairs 1 and 2, 3 and
4, and 5 and 6 on the options jumper block (J8) for assigning the
ID. The chart in Figure 2 shows you how to place the jumpers to

assign ID values 0 through 7. Be sure that the ID you choose is
not used by another device on the SCSI bus.
Your Seagate drive is shipped by the factory configured as SCSI
ID 3—jumpers are attached to pins 3 and 4 and pin 5 and 6. You
must reconfigure the SCSI ID 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 SCSI adapter recognizes as the first position on 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 that you 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 is required, it will be provided by the 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
command from the host before it starts or stops the spindle motor.
Parity enable. Parity is a method that is sometimes used for error
detection. The drive is shipped with parity enabled.
Terminators. The drive is designed with single-ended drivers
and receivers and must be used with other SCSI devices that use
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-
Medalist 1080sl SCSI Installation Guide, August 19959
nators enabled. If you are positioning the drive at the end of the
cable, you must enable the drive’s internal terminators or attach
an external terminator to the end of the cable. Terminators on the
devices between the bus ends must be disabled or removed.
• To enable the drive’s terminators, leave the pin-pair 19 and 20
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 provides settings for four implementations of terminator power:
• Terminator power to the drive terminator and the SCSI bus—
install jumpers on pins 21 and 23 and on pins 22 and 24 of 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.
10Medalist 1080sl SCSI Installation Guide, August 1995
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 connector and 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
must align with pin 1 of the other SCSI devices attached to the
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. Connecting a remote LED. (Optional) Connect a remote LED
to pins 9 and 10 of jumper block J8. Pin 9 is ground.
3. Attach an available power cable to the drive.
Medalist 1080sl SCSI Installation Guide, August 199511
Mounting the drive
Required materials:
• Four 6-32 UNC-2A screws (not included)
The drive fits in the standard 3.5-inch bay and can be mounted
in any orientation. Position the drive so that the cables are not
strained or crimped. Secure it with four mounting screws not more
than 6 full turns (0.20 inches) into the drive frame (see Figure 3).
Caution. To prevent drive mounting-hole damage, use only the
type of screws specified.

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 partitioning and formatting the drive and may require a special device
driver or installation software depending on the operating system
you are using and your SCSI adapter. Refer to your SCSI
adapter’s documentation for specific information on how to configure your drive.
This guide describes a typical configuration for a PC using DOS
and one or two SCSI drives only.
System setup configuration
Required materials:
• A bootable diskette with the Format and FDISK command
If you are replacing the ATA (IDE) drive or drives in your computer
with SCSI, you must reset the drive-type configuration listed in
System Setup to
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
5. Save the changes and exit System Setup.
Low-level formatting
Your drive was low-level formatted at the factory to 512 bytes per
sector. You do not need to low-level format it again. If you choose
Not Installed

Medalist 1080sl SCSI Installation Guide, August 199513
to low-level format the drive, use the 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
You must partition the drive into one or more logical drives before
you can use it.
Caution. Partitioning or formatting a drive at any level erases all
data on it. Make a backup copy of your existing files on
another drive before you repartition or reformat. Seagate assumes no liability if you erase your data.
To partition the drive:
1. Insert a bootable diskette into Drive A. Turn the computer on.
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
Note. If you have two or more drives in your system, the menu
displays five options. Option five allows you to select
the drive you want to partition. Make sure you select the
correct drive.

High-level formatting
High-level formatting verifies the information written by the lowlevel format and builds the file allocation table (FAT) used by DOS
to access files on the drive. If you put more than one partition on
the drive, you must high-level format each partition. Refer to your
DOS reference guide for instructions. Use the DOS FORMAT
utility to high-level format the drive as follows:
1. Type the following command at the DOS prompt:
drive:
format
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 tells the 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 the computer to copy the necessary system files 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
/v /s
ENTER.
Medalist 1080sl SCSI Installation Guide, August 199515
NonDOS operating systems
If you are installing the drive in a system that is using an operating
system other than DOS, you may need a device driver or installation software. The device driver is provided by your SCSI
adapter manufacturer and is operating-system specific. It is provided on a diskette that comes with the adapter. Refer to the SCSI
adapter’s documentation for instructions on how to install the
device driver. If you do not have a device driver for the operating
system you want to install, contact the SCSI adapter manufacturer.
Installation software may be required to install the drive in some
systems. There are many reputable third-party installation software 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 instructions 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 SCSI adapter’s user guide for assistance preparing
the SCSI adapter and installing the drive.
If you have trouble installing the drive with the network software,
try installing it with DOS to ensure that the drive is working
correctly.

Basic troubleshooting
Warning. Always turn off the system before changing jumpers or
unplugging cables and cards.
If your drive does not respond or function properly when you turn
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. A damaged ribbon cable or connector strain relief can
cause the SCSI bus to fail.
Verify that the pins 1 of each device on the cable are aligned.
Use the edge-stripe on the cable to denote pin 1.
Caution. Improperly aligning or reverse-plugging pin 1 of 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 the terminator configuration. If the drive is at the end
of the bus and external termination is not used, the drive’s
terminator must be enabled. Disable or remove termination on
all devices between the drive and the device at the other end
of the bus.
If the drive is not the last device on the bus or if external
termination is used, be sure to remove the jumper that enables
the drive’s termination.
Medalist 1080sl SCSI Installation Guide, August 199517
Make sure that the drive is running. Listen carefully for the
drive motor spinning. Also, the drive-activity LED flashes when
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 settings.
• Check the CMOS drive type. If you have an AT system, the
CMOS drive-type parameter values must be set to zero or
Installed
• 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.

Advanced troubleshooting
If you have performed the preceding basic checks but the problem 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
that the pins 1 are aligned. Make sure the cable is not crimped
or damaged.
• Check all cards for proper seating.
• Check your host adapter’s BIOS memory address setting.
Make sure that it does not conflict with another device that sets
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 the Drive C partition with the FDISK utility. The partition
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.
Medalist 1080sl SCSI Installation Guide, August 199519
• If the drive is at least the third drive in your system, you may
need to configure the BIOS for three or more drives or install
a device driver. Refer to your host adapter’s user guide for
assistance. Contact the host adapter manufacturer for the
device driver if one is required.
System error message, “Drive not Ready,” appears.
• Check all cables. For each ribbon cable, verify that pin 1 of the
cable is aligned with pin 1 of the connector. Pin 1 is usually
denoted by a stripe on the side of the ribbon cable.
• Check the power supply specifications.
• Turn off the system and wait 20 seconds. Turn it back on and
make sure the drive spins up. If the drive does not spin up,
check the drive power cable.
The screen stays blank when you power up the system.
• Make sure the monitor is plugged in and turned on.
• Check all cards. Make sure the video card is seated in its slot
and secured with mounting screws.
• Check all cables. Make sure the video card cables are securely attached.
• Turn off the computer and remove all cards except the video
card. Boot the computer. Power down the computer and add
another card. Reboot. Repeat these steps until a failure occurs.
The system hangs in FDISK or fails to create or save the
partition record.
• Check all cables.

• The DOS utilities diskette may be corrupted. Try your backup
DOS diskette.
• If you have DOS Version 4.0 or earlier, make the drive partitions smaller.
• Check for media defects at the beginning of the drive. Use a
third-party surface scan utility.
The FDISK error message, “No Fixed Disk Present,” appears.
• Check all cables.
• Check the power supply specifications.
• Make sure the drive spins up when you turn on the system.
• In AT systems, check the drive type. The drive type must be
set to Not Installed or the drive-type values set to zero.
• Check for I/O address conflicts.
During the DOS high-level format, the drive keeps retrying
hard errors and reporting the following message. “Attempting to recover allocation units. . .”
• This is normal with DOS Version 4.0 or later.
DOS messages, “Disk Boot Failure,” “Non-System Disk,” or
“No ROM Basic - SYSTEM HALTED,” appear.
• Remove the diskette from the diskette drive.
• Check all cables.
• Use the same version of DOS throughout your system.
• Reinstall the DOS system files using the DOS SYS utility.
• Make sure the primary partition is active in FDISK.
• Check for viruses.
