The Easiest Way to Install Your Drive

DiscWizard™ is Seagate’s exclusive Windows program that is included with your drive for easy drive installation. You can use this software if you already have a bootable hard drive in your computer and you are running Windows 98 or Windows 95.

Run DiscWizard before installing your drive for customized step-by-step instructions for your system.

To run DiscWizard:

•Select Run from the Windows Start menu and type x:\setup, where x is the drive letter of your diskette or CD-ROM.

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

What You Need

•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 66 (max length: 18 inches)

•An unused drive power cable for your new drive

Ultra ATA/66 Requirements

The drive can support transfer rates up to 66 Mbytes per second (UDMA 4) in Ultra ATA/66 mode. For your drive to run in this mode, you need the following:

•A computer that supports UDMA modes 3 and 4

•A 40-pin 80-conductor cable (available from your dealer)

•A software utility to confirm and activate Ultra ATA/66. Seagate® provides a utility called UATA66.exe that is included on your CD, or you can download it from our Web site at www.seagate.com.

•The Windows 98 operating system

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 will minimize 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 below to configure the drive for your system.

•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.

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.

		Note. If you are using a 40-pin 80-conductor
Master			cable, attach the blue connector to the
	Pin 1		motherboard, the black connector to the
			master drive, and the grey connector
Slave		Computer
			to the slave.

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

Note. You can mount the drive in any orientation. Usually it is mounted 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 this is not available, select “User- defined drive type” and enter the CHS (cylinder, head, sectors) parameters for your drive from the table listed below. The CHS addressing supports capacities up to 8.4 Gbytes only. To access the full capacity of the drive, use LBA mode.

4.Save and exit the system setup program.
