The easiest way to install your drive

DiscWizardTM, available exclusively from Seagate®, provides you with cus- tomized installation instructions for your hard drive. You can get this free disc drive installation software from our web site at www.seagate.com/sup- port or run the program directly from your web browser. In either case, you should run DiscWizard before you install your drive.

To run DiscWizard:

Follow the instructions on the download page at www.seagate.com to cre- ate a diskette and complete the installation.

If you cannot run DiscWizard, follow the instructions on this installation sheet to install and configure your drive.

•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.

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 computer dealer)

• A software utility to confirm and activate Ultra ATA/100. Seagate pro- vides 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 sup- ports Ultra ATA 100.

•Drive electronics are extremely sensitive to static electricity. While installing 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.

•Do not apply pressure or attach labels to the drive.

Setting the jumpers

Refer to the jumper settings illustration below or on your drive label to con- figure 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: Computers that use cable select to determine the master

and slave drives by selecting or dese-
lecting pin 28, CSEL, on the interface
bus. To enable cable select,	set a				Options jumper block

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 con- nector locations).

Caution. Align pin 1 on the motherboard connector with pin 1 on your

Large disc requirements (for capacities over 137 Bytes)

To realize the full capacity of drives over 137 Gbytes:

• Use an operating system that supports 48-bit addressing:
- Microsoft Windows XP Home with Service Pack 1
- Microsoft Windows XP Professional with Service Pack 1
- Windows 2000	Professional with Service Pack 3
- Windows 2000	Server with Service Pack 3
• Use a 48-bit compatible Ultra ATA/133 PCI host adapter card or connec-
tor on your motherboard.

	Note.

When configuring two ATA devices on the same cable, both must use Cable Select or both must use Master/Slave jumper settings. If using a standard 40-pin cable, the master and slave drives can be placed in any position. If 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.

Breather filter hole precaution

Caution. Do not cover, seal, or insert any object into this hole. This hole has two purposes:

•To allow condensation inside the hard disc to escape

•To allow air pressure inside the hard disc to equalize with ambient pres- sure

If this hole is covered, sealed, or penetrated by any object, the drive reli- ability may be compromised and could lead to permanent damage—doing so voids the warranty.

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 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.

Note. Do not overtighten the screws or use metric screws. This may dam- age the drive.

3. Attach the interface connector and the power connector to the drive.

Configuring the BIOS

Close your computer case and restart your computer. your computer may automatically detect your new drive. If your computer does not automati- cally detect your new drive, follow the steps below.

a.Restart your computer. While the computer restarts, run the System Setup program (sometimes called BIOS or CMOS setup). This is usu- ally done by pressing a special key, such as DELETE, ESC, or F1 dur- ing the startup process.

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.

When your computer restarts, it should recognize your new drive. If your system still doesn’t recognize your new drive, see the troubleshooting sec- tion on the back of this sheet.
