What you need
•Straight-edge and Phillips screwdrivers
•Drive mounting screws
•A SCSI interface host adapter
•A 50-pin SCSI interface cable
•An unused drive power cable for your new drive
•A DOS or Windows 95 system setup diskette (Seagate recom-
mends using DOS Version 5.0 or later).
•If you are mounting this 3.5-inch drive in a 5.25-inch drive bay,
you need a mounting adapter or frame kit. Also, you may need
drive mounting rails if your drive bay is not designed for direct
mounting.
Before you begin
•Make sure your computer is turned off before you open the
case.
•Read the handling precautions following and inspect the drive
to make sure that it is not damaged.
•Save your foam-lined Seagatedisc drive box. This box has
been approved by Seagate for shipping a Seagate disc drive.
Using any other container or packing material voids your drive
warranty.

2 Medalist Pro 2160N, Rev. B
Handling precautions
Disc drives are extremely fragile. Do not drop or jar
your drive.
Keep the drive in its antistatic bag until you are
ready to install it.
Protect your drive from static discharge by making
sure you are well grounded before touching the
drive. We recommend wearing a grounded wrist
strap throughout the installation process. Do not
touch the connectors or any part of the printed cir-
cuit 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.

Medalist Pro 2160N, Rev. B 3
SCSI ID jumpers and drive termination
Setting the SCSI ID
Your SCSI drive is configured at the factory as SCSI ID 0 (no
jumpers installed). If you are installing only one drive or if this will
be your boot drive, the drive should be configured as SCSI ID 0.
Each device on the SCSI chain must have a unique SCSI ID. If
you are installing a second hard drive, choose the next available
ID. SCSI ID 7 is usually reserved for the SCSI host adapter.
Figure 1 on page 4 shows the jumper settings for SCSI IDs 0
through 7.

SCSI termination
Figure 2. Termination for internal SCSI devices
Chains of SCSI devices must be terminated at each end of the
cable.
The figure above shows two internal hard drives with the termi-
nation enabled for the SCSI host adapter and the last device on
the cable.
If your new drive is the last device on the SCSI cable, you must
enable termination. Active termination is enabled when there are
no jumpers on pins 11 and 12 of the options jumper block. This
is the default setting.
If your drive is not the last device on the SCSI cable, SCSI termi-
nation must be disabled by placing a jumper on pins 11 and 12.

Figure 3. Termination for internal and external SCSI devices
This figure shows a SCSI chain with two internal SCSI devices
and two external SCSI devices. The SCSI devices at the ends of
each cable are terminated.
Note. Some SCSI host adapters should remain terminated
even if they are in the middle of the chain. Also, some
adapters treat the internal and external chains as sepa-
rate logical buses. This means you may need to termi-
nate both the first and last devices on both logical buses
to achieve proper termination. Refer to your computer or
host adapter documentation to see how this is handled in
your system.

Attaching cables and mounting the drive
1. If you are installing a new SCSI interface cable, attach one
end of the cable to the interface connector on your computer
or host adapter.
2. Thread the interface cable through the drive bay and attach
the connector at the end of the interface cable to your new
drive.
Note. If you have two drives, attach the second drive to the sec-
ond connector.

Figure 4. Attaching the cables
Caution. To avoid possible damage to your system,
make sure to align pin 1 on the SCSI host adapter with
pin 1 on the SCSI cable on your drive or drives. Pin 1
on the interface cable is usually indicated by a stripe
along the edge of the cable.

Figure 5. Mounting screws
3. Slide the drive carefully into the drive bay. Secure the drive
with four 6-32 UNC-2A mounting screws in either the side-
mounting holes or the bottom-mounting holes. Do not over-
tighten the screws. They should be inserted no more than six
full turns into the drive frame. Do not use metric screws.
Caution. To avoid possible damage to the drive, do not
overtighten the screws or use metric screws.

Note. If you are mounting the drive in a 5.25-inch drive bay, you
need a mounting adapter or frame kit. Contact your com-
puter dealer. Some computers also require drive mount-
ing rails, which can be obtained from your distributor or
computer manufacturer.
4. Attach a power cable to each drive. If your computer does not
have an unused power connector, you can purchase a Y-
shaped power cable from your computer dealer.
5. Check all cable connections and then replace your computer
cover. Continue to “Configuring your computer.”

Configuring your computer
Before you format or partition your new drive, you must configure
your computer’s BIOS to show that no hard drives are installed.
1. Turn your computer on. As your computer starts up, watch the
screen for a message that describes how to run the system
setup program (also called BIOS or CMOS setup). This is
usually done by pressing a special key, such as DELETE, ESC
or F1, during startup. See your computer manual for details.
Press the appropriate key to run the System Setup program.
If you have no ATA drives in your computer, your BIOS should
be configured to show that no hard drives are installed.
2. Set the drive type in your System Setup program to
zero,
none or not installed .
3. Save the settings and exit the System Setup program. Your
computer will automatically reboot.

12 Medalist Pro 2160N, Rev. B
Partitioning and formatting your drive
To prepare your drive for use with any of these operating sys-
tems, you must partition and format your drive. Use your system
setup diskette to automatically take you through the formatting
process. Caution. Partitioning or formatting a drive erases all
data on it. Seagate assumes no liability if you erase
your data.
Low-level format
This drive is low-level formatted at the factory to 512 bytes per
sector. You do not need to low-level format. If necessary, SCSI
host adapters have diagnostic capability for low-level formatting.
Refer to your host adapter manual for diagnostic instructions.
DOS, Windows 95, Windows NT and OS/2
Drive partitioning
Partitioning a hard drive divides it into sections (partitions) that
function as separate logical drives (labeled C,D,E, etc.). In creat-
ing partitions, keep in mind that the larger the partition, the more
drive space is taken up in incomplete sectors. For this reason, if
most of your files are smaller than 50 Kbytes, you should use
partitions of 1 Gbyte or less. To partition your new drive:
1. Insert a bootable DOS diskette into your diskette drive and
restart your computer.
2. Insert a DOS program diskette that has the FDISK.EXE and
FORMAT.COM programs into your diskette drive. At the A:
prompt, type fdisk and press ENTER.
!

Medalist Pro 2160N, Rev. B 13
3. If you have two hard drives installed, the FDISK menu dis-
plays five options. Option five allows you to select the drive
you want to partition. Make sure that your new drive is
selected. If you accidently repartition your old hard drive, you-
will erase all data on the drive.
4. Select “Create DOS partition or logical DOS drive” by press-
ing 1. Then press ENTER.
5. Select “Create primary DOS partition” by pressing 1 again.
Then press ENTER.Create your first drive partition. If you are
creating a partition that will be used to boot your computer
(drive C), make sure the partition is marked
active.
6. Create an extended partition and additional logical drives, as
necessary, until all the space on your new hard drive has
been partitioned.
7. When partitioning is complete, FDISK reboots your computer.
Drive formatting
Caution. Make sure to use the correct drive letters so
that you do not format a drive that already contains
data.
At the A: prompt, type format
x :, where
x is the letter of your
new partition. If this is your boot drive, type format
x : /s. Repeat
the format process for all the new partitions you have created.
After you format your drive, it is ready to use.
You’re Done!

Other operating systems
Macintosh
To configure your drive for a Macintosh system, you must use a
third-party hard disc initialization program. Most software ven-
dors and computer stores that carry Mac software sell hard disc
drivers. Refer to the software instructions for details.
Note. The Apple HD SC Setup utility included with your Macin-
tosh system software only works on drives ordered
directly through Apple.
Unix
There are several versions of the UNIX operating system. Each
of these handle hard disc drive installation in a different manner.
For this reason, refer to your system’s operating manual for infor-
mation about how to complete the installation of your disc drive.
Netware
To configure the drive for Netware, refer to your Netware user’s
guide for installation instructions.

Medalist Pro 2160N, Rev. B 15
Additional drive options
Figure 7. Options jumper settings
The options jumper block allows you to configure your drive for
several additional configuration options. The drawing in Figure 7
shows how to place jumpers to enable each optional feature. A
brief description of each option is included.
Parity Enable. Parity is enabled when a jumper is installed on
pins 7 and 8 (default). To disable parity, remove this jumper.
Motor Start Enable. The Motor Start option causes the drive to
wait for a Start/Stop Unit command from the host before starting
or stopping the spindle motor. Motor start is enabled when a
jumper is installed on pins 11 and 12.
