What You Need
•
A Phillips screwdriver and four 6-32 UNC drive mounting screws
•
A standard 40-pin ATA interface cable,
or
an 80-conductor cable to run Ultra
ATA 100 (max length: 18 inches)
•
An unused drive power cable for your new drive
•
A version of Windows with FAT32 file system for drives over 32 Gbytes
Ultra ATA/100 Requirements
The drive can be configured to support a default maximum transfer rate. This
drive can support transfer rates up to 100 Mbytes per second (UDMA 5) in
Ultra ATA/100 mode. Using a software utility, you can set the default transfer
rate to the best capability of your system. For your drive to run in this mode,
you need the following:
•
A computer that supports UDMA mode 5
•
A 40-pin, 80-conductor cable (available from your dealer)
•
A software utility to confirm and activate Ultra ATA/100. Seagate provides
a utility called UATA100.exe. You can download the latest version from our
Web site at www.seagate.com.
•
Windows XP, Windows Me, or Windows 98 operating system which
supports Ultra ATA 100
Handling Precautions
Disc drives are extremely fragile.
Do not
drop or jar the drive.
Keep the drive in the protective SeaShell™ container until you are
ready to install it. This minimizes handling damage.
The drive has a protective cover called SeaShield
®
. Do not remove this
permanent cover—it protects the drive from electrostatic discharge
(ESD) and minor impact damage.
Protect your drive from static discharge by wearing a grounded wrist
strap throughout the installation process.
Always handle the drive by the edges or frame.
Do not apply pressure or attach labels to the circuit board or the top of
the drive.
Setting the Jumpers
Refer to the jumper settings on your
drive label to configure the drive for your
system. Jumper settings can also be
accessed online from our Web site at
www.seagate.com.

•
Master or single drive: The drive is shipped configured for a master or a
single drive with a jumper set on pins 7 and 8.
•
Drive is slave: To configure the drive as a slave, or second drive on the
cable, remove all the jumpers.
•
Master with non-ATA compatible slave: Use this setting if the slave
drive is not recognized. Configure the master drive with a jumper set on
pins 5 and 6 and pins 7 and 8 to enable this option.
•
Cable-select option: Computers that use cable-select determine the
master and slave drives by selecting or deselecting pin 28, CSEL, on the
interface bus. To enable cable select, set a jumper on pins 5 and 6.
•
Alternate capacity jumper: Drives with a 40-Gbyte capacity are limited
to 32 Gbytes. This jumper is used to provide a solution to specific legacy
BIOS problems. When using the alternate capacity jumper, Disk Manager
software is required to achieve the drive’s full capacity.
Attaching Cables and Mounting the Drive
1. Attach one end of the drive interface cable to the interface connector
on your computer’s motherboard
(see your computer manual for
connector locations).
!
Caution. Align pin 1 on the motherboard
connector with pin 1 on your drive connector.
Pin 1 is marked by a stripe on one side
of the cable.
2. Attach the interface
connector and the power
connector to the drive.
Note. You can mount the
drive in any orientation,
however, the most common
orientation is with the circuit
board down.
3. Secure the drive in the computer using four 6-32 UNC mounting screws
in either the side-mounting or bottom-mounting holes. Insert the screws
no more than 0.20 inch (5.08 mm) into the bottom-mounting holes and no
more than 0.14 inch (3.55 mm) into the side-mounting holes.
!
Caution. Do not overtighten the screws or use metric screws. This
may damage the drive.
Configuring the BIOS
For your computer to recognize your new drive, configure your computer’s
BIOS as follows:
1. Run the system setup program.
2. Enable LBA mode and UDMA mode, if available.
3. Select the auto-detect option. If necessary, refer to the drive parameters
on your drive label to configure the drive for your system. BIOS settings
can also be accessed at www.seagate.com. To access the full capacity
of the drive, use LBA mode or use Disk Manager.
4. Save and exit the system setup program.
