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).
Note. When configuring two PATA devices on
the same cable, both must use Cable
Select or both must use Master/Slave

What you need
• A Phillips screwdriver and four 6-32 UNC drive mounting screws
• An ATA interface cable. For optimum performance use an 80-conductor
Ultra ATA/100 cable which has blue, gray, and black connectors.
Motherboard
drives can be placed in any position. If you
are using a 40-pin 80-conductor cable, attach
the blue connector to the motherboard,
the black connector to the master drive
and the grey connector to the slave drive.
Slave
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. Secure the drive using four 6-32 UNC mounting screws in either the
side-mounting or bottom-mounting holes. Insert the screws no more than
0.20 inches (5.08 mm) into the bottom-mounting holes and no more than
0.14 inches (3.55 mm) into the side-mounting holes.
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:
Note. Do not overtighten the screws or use metric screws. This may dam-
age the drive.
• A computer that supports UDMA mode 5
3. Attach the interface connector and the power connector to the drive.
• A 40-pin, 80-conductor cable (available from your computer dealer)
• Windows XP, Windows 2000, Mac OS X, Linux, or other operating system
that supports Ultra ATA 100.
Breather filter hole precaution
Large disc requirements (for capacities over 137 Gbytes)
To realize the full capacity of these drives:
• Use an operating system that supports 48-bit addressing:
- Microsoft Windows XP with Service Pack 1 (or later)
- Windows 2000 with Service Pack 3 (or later)
- Mac OS X10.2 (or later)
- Mac OS 9.2.2 (or later)
- Linux kernel v2.4.16 (or later)
• Use a 48-bit compatible Ultra ATA/133 PCI host adapter card or connector.
Breather hole
Do not cover or seal
this hole.
Caution. Do not cover, seal, or insert any object into this hole.
Handling precautions/electrostatic discharge protection
• Disc drives are fragile. Do not drop or jar the drive. Handle the drive only
by the edges or frame.
• Drive electronics are extremely sensitive to static electricity. While install-
ing the drive, wear a wrist strap and cable connected to ground.
• Turn off the power to the host system during installation.
• Do not disassemble the drive; doing so voids the warranty. Return the
entire drive for depot service if any part is defective.
This hole allows condensation inside the hard disc to escape and allows
pressure inside the hard disc to equalize with ambient pressure If this hole is
covered, sealed, or penetrated by any object, drive reliability may be compro-
mised and could lead to permanent damage and voids the warranty.
Configuring the BIOS (does not apply to Apple Macintosh systems)
Close your computer case and restart your computer. Your computer may
automatically detect your new drive. If your computer does not automatically
detect your new drive, follow the steps below.
• Do not apply pressure or attach labels to the drive.
a. Restart your computer. While the computer restarts, run the System
Setup program (sometimes called BIOS or CMOS setup). This is usually
done by pressing a special key, such as DELETE, ESC, or F1 during the
startup process. See your system documentation for details about your
particular system.
b. Within the System Setup program, instruct the system to auto detect
your new drive.
c. Enable LBA and UDMA modes if available and then save the settings
and exit the Setup program.
Setting the jumpers
Refer to the jumper settings illustration below or on your drive label to config-
ure the drive for your system. Jumper settings can also be accessed online
• Master or single drive: When this jumper is used (connecting pins 7 and
8), the drive is configured as master or single drive.
• Drive is slave: To configure the drive as a slave or second drive on the
cable, remove all the jumpers from
pins 5-8.
• Master with non-ATA compatible
slave: Use this setting if the slave
drive is not recognized. Configure the
When your computer restarts, it should recognize your new drive. If your sys-
tem still doesn’t recognize your new drive, see the troubleshooting section.

3. Restart the computer while holding the C key (you can release the C key
after you see the Apple logo appear on the screen). In Mac OS X 10.4 or
later, you must select your language after booting from these install

BIOS that does not support large capacity disc drives. When using the
alternate capacity jumper, DiscWizard® Starter Edition software is
required to achieve the drive’s full capacity.
5. Select the drive you want to install in the left panel.
Warning. Be sure to select the correct disc before erasing the drive.
