SOFTWARE INSTALLATION

Before using the new hard drive, you need to configure your system BIOS (CMOS Setup program) and partition and format the hard drive.

CMOS Setup

The computer system provides an initial setup utility (CMOS Setup) that allows you to tell the system what type of hardware you are using. You access CMOS Setup with a series of keystrokes or run it from a disk or CD-ROM. CMOS setup procedures vary from system to system. Follow the setup instructions in your computer system manual.

To configure your system for LBA mode:

1.Enter your CMOS Setup program (sometimes called the Setup program). Refer to your system manual for instructions.

Important: If you are installing the 2.5 GB or larger drive and are not able to access your CMOS Setup, refer to the 2.5 GB or Larger Hard Drives section on page 5.

2.Select an auto config drive type. The full capacity of your drive should display. See Table 1 for the full capacity of your drive in CMOS.

Tips:

If your CMOS setup does not have an auto config drive type, try selecting Type 01. Then install EZ-Drive.

If your system does not have auto config or Type 01 drive types, try user defined and enter 1023x16x63 for the drive parameters. Then install EZ-Drive.

Note: Western Digital defines a decimal megabyte as 1,000,000 (106) bytes. CMOS defines a binary megabyte as 1,048,576 (220) bytes. This is why different utilities report different hard drive capacities.

3.Enable options such as LBA or Translation Mode. If you don’t have either options, you need to upgrade the BIOS or install EZ-Drive. See Troubleshooting for a list of BIOS sources and phone numbers.

Partitioning and Formatting

Your Western Digital hard drive has been low-level formatted at the factory. The hard drive is ready to set up and is defect-free. You must partition and high-level format the hard drive so it can accept files.

There are two ways to format and partition the hard drive.

1.Use the EZ-Drive software that you received with the hard drive.

2.Use the DOS utilities FDISK and FORMAT.

We recommend using EZ-Drive. It is a safe, fast, and an easy way to partition and format the hard drive. See the section Using EZ-Drive Software for instructions.

For instructions on using FDISK and FORMAT, see your DOS user manual.

Note: DOS has a 2.1 GB partition limit. If you have a 2.5 GB or larger hard drive, you must create at least two partitions to access the full capacity.

EZ-Drive 8.x Software Overview

EZ-Drive 8.x software is included with the Western Digital hard drive to help you:

Partition and format your new hard drive.

Overcome the 528 MB barrier.

Overcome the 2.1 GB barrier.

If you did not receive the EZ-Drive software, you can download it from our web site at www.wdc.com.

Partition and Format: If your system supports the full capacity of the hard drive, EZ-Drive will only partition and format the hard drive. It does not install code on your boot sector.

528 MB Barrier: Most computer systems built before August 1994 do not support hard drives larger than 528 MB, unless the BIOS is updated or third-party software such as EZ-Drive is installed.

2.1GB Barrier: Some computer systems built before early 1996 do not support hard drives with more than 4095 cylinders (hard drives larger than 2.1 GB), unless the BIOS is updated or third-party software such as EZ-Drive is installed.

EZ-Drive Help Files: To access EZ-Drive help files on the installation disk, select Installation Help from the EZ-Drive main menu.
