Read before you begin...
Application. Your Seagate® drive is designed for NRTL-listed
personal computers. It uses the ATA interface.
Warning. Turn off the computer before you open the case, touch
any internal components or install the drive.
Static discharge. Your drive and computer contain components
that can be damaged by static discharge. Static electricity is
generated from the friction of two contributors rubbing together.
The charge is stored in your body and is discharged when you
touch another conductor. Wool, synthetic clothing, carpets and
plastics, including most bags, are common contributors. Observe
these precautions to avoid damage from static electricity:
• Ground yourself before handling the drive. Wear a grounded
wrist strap that is properly connected to earth ground, or touch
the metal chassis of the computer power supply if it is plugged
into a grounded outlet.
• Keep the drive in its antistatic bag until you are ready to install
it. Do not attach any cables to the drive in the antistatic bag.
• Handle the drive gently and only by its edges or frame.
• Do not touch the drive’s connector pins or printed circuit board.
Drive handling. The drive is extremely fragile—handle it with
care. Do not remove any labels from the drive.
Inspection. Hold the drive by the frame edges to inspect it. Call
your distributor or dealer immediately if it appears to be damaged.
Warranty. See your authorized Seagate distributor or dealer for
the terms of the drive warranty.
Note. With regard to the EZ-Drive software, there are no warran-
ties, express or implied, including, but not implied, warranties of merchantablity or fitness for a particular purpose. All
such warranties are expressly and specifically disclaimed.
2 Medalist XE Family Installation Guide, Rev. A
Maintenance and repair. Seagate drives do not require mainte
nance. The head/disc assembly is factory-sealed; a broken seal
voids the warranty. Seagate customer service centers are the
only facilities authorized to repair Seagate drives. Seagate does
not sanction any third-party repair facilities.
Note. Throughout this manual, the Medalist 275xe is referred to
by its model number, ST3295A, and the Medalist 545xe is
referred to by its model number, ST3660A.
ST3660A free installation software
Files containing the free hard disc installation software and a
program for extracting them, Seamove, are written on the
ST3660A drive at the factory. The installation software is a
version of EZ-Drive for Seagate. It provides a software solution
for computers using DOS and some BIOS combinations that limit
the hard disc capacity to 528 Mbytes. It allows the computer to
access the ST3660A’s entire 544.8 Mbytes. Before you partition
and format the drive, transfer the EZ-Drive files to a bootable
diskette. Instructions for transferring the EZ-Drive files are on
page 11 and in the README.EXE file on the drive.
Note. The EZ-Drive software is authorized for installation only
with the drive on which it is shipped.
Quick software transfer
• Install the ST3660A drive.
• Boot the computer with a diskette that has 300 Kbytes avail-
able for transferring the files.
• Select drive type 2 for the ST3660A in CMOS.
• Activate the prompt for the ST3660A.
• Type seamove. Seamove transfers the files to the diskette in
Drive A, erases the drive partition and reboots the computer.

Installing the drive
1. Turn the computer off.
Warning. Installing or removing the drive or adapter cards
while the computer is powered on can damage
your drive, adapter and computer.
2. Remove the computer’s cover.
Caution. Special training or tools may be required to service
laptop computers. Removing the cover may void
your warranty. Review the terms and conditions of
your warranty before removing the cover.
3. Ground yourself.
Configuring the drive
Your ST3295A or ST3660A is configured at the factory for singledrive operation. If you are installing two drives, you must reconfigure your Seagate drive as either the master or the slave. If you
install the Seagate drive as your only drive but add a second drive
later, you must reconfigure it as the master or slave at that time.
1. Remove the drive from its antistatic bag.
2. Install master/slave jumpers. The master/slave configura-
tion is set using the jumper block shown in Figure 1 on page
3. The chart below the jumper block shows how to set the
jumpers for different configurations. An extra jumper is included with the drive and is attached to pins 1 and 3 of the
jumper block.
Installing one drive: No jumper setup is required.
Installing two drives: Your Seagate drive may be installed
with another ATA-compatible drive. Your system may use
either a standard ATA interface cable or the cable-select
method. The chart in Figure 1 shows the jumper settings for
the master and slave configurations.
Medalist XE Family Installation Guide, Rev. A 5
Attaching cables
Refer to Figure 1 on page 3 for the locations of the connectors.
1. Connect the remote LED (optional).
2. Attach the power cable. Attach one of the cables from the
power supply to the power connector on the drive.
Caution. The cable and connector are designed to mate. Do not
force a connection. Improper alignment may damage
your drive.
3. Attach the interface cable. The edge-stripe on the interface
cable for the drive is used to denote pin 1. The cable length
must be no longer than 18 inches.
Caution. Cable misalignment can result in damage to the com-
puter and the drive. Ribbon cables are delicate—be
careful not to crimp or strain them.
Installing one drive with a standard ATA 40-pin interface cable:
Attach one end of the cable to the drive’s 40-pin ATA interface
connector. Align the cable’s edge-stripe with pin 1 of the drive
shown in Figure 1. Attach the other end of the cable to the host
adapter card or to the hard drive connector located on the
motherboard. Align the cable’s edge-stripe with pin 1 (see your
system user’s guide or host adapter user’s guide).
Installing two drives with an ATA interface cable:
You need an interface cable designed for two drives. Attach a
cable connector to each drive’s 40-pin ATA interface connector. Align the cable’s edge-stripe with pin 1 of the drive shown
in Figure 1. Attach the other end of the cable to the host
adapter card or to the hard drive connector located on the
motherboard. Align the cable’s edge-stripe with pin 1 (see your
system user’s guide or host adapter user’s guide). You can
attach the drives in any order on the cable.
6 Medalist XE Family Installation Guide, Rev. A
Installing drives in computers that use cable-select:
If your computer uses the cable-select method, refer to your
computer reference guide to determine which cable connector
or drive slot denotes the master drive and which the slave.
Mounting the drive
Your Seagate drive is designed to fit into a 3.5-inch bay. You can
mount the drive securely in the computer in any orientation using
either the side mounting holes or the bottom mounting holes.
Position the drive so that you do not strain or crimp the cables.
Your Seagate drive is not shipped with mounting screws. Use the
screws in the current drive if this drive is a replacement.
• Drives that have an “S” stamped on the frame runner use
6-32 UNC standard screws.
• Drives that have an “M” stamped on the frame runner use M3
metric screws.
Caution. To prevent drive mounting hole damage, use only the
appropriate type of screws as specified. Tighten them
gently using no more than 6 inch-lb of torque.
Bottom mounting holes. Insert four mounting screws not more
than 0.20 inches (6 full turns) into the drive frame.
Side mounting holes. Insert four mounting screws not more than
0.13 inches (4 full turns) into the drive frame.
5.25-inch drive bay. You can mount your drive in a 5.25-inch
drive bay with a Seagate 5.25-inch frame kit. Contact your dealer
for the frame kit you need.

Configuring the computer
Your computer maintains records representing the hardware in
the system. This representation includes the translation geometry
that is used by the BIOS to map the drive surface and that is
stored in CMOS memory. During the boot cycle, a test is run
comparing the record to the hardware. When you install a new
drive, you must update this record to include a representation of
the new drive. This is done in your computer’s System Setup.
This section tells you how to configure your computer. It also
discusses drive capacity limitations imposed by some computers
and available solutions. If you are installing a ST3295A, go to the
“Standard installation” section on page 8.
528-Mbyte system-capacity limit
Computers using DOS and some BIOS impose a 528-Mbyte
capacity limit on ATA hard discs. This occurs because the BIOS
is designed to use up to 1,024 cylinders in the translation geometry for mapping the data surface of the drive. The ST3660A has
1,057 cylinders. If your computer’s BIOS limits the drive capacity
to 528 Mbytes, you have several options for installing the drive.
• Install the drive using the standard installation procedure on
page 8. This assures you the maximum capacity allowed by
your computer.
• Use a host adapter that supports more than 528 Mbytes.
• Upgrade the BIOS to one that uses logical block addressing
(LBA) or an extended cylinder-head-sector (ECHS) addressing scheme that allows for more than 528 Mbytes.
• Use the hard disc installation software, EZ-Drive, included on
your ST3660A drive. Instructions for extracting the software
are on page 11. Instructions for using EZ-Drive start on page
12
.
(Only ST3660A drives with part number 958002-4xx are
shipped with EZ-Drive.)

Standard installation
1. Turn the computer on.
2. Enter the System Setup routine. (Refer to your computer
user’s guide. System Setup may be called Setup, BIOS Setup
or CMOS Setup.) If your computer uses an automatic setup
utility, see the caution below.
3. Find the hard disc configuration in the System Setup screen.
4. Select a drive type that matches the drive translation geometry
for your drive as shown in the following table.
