HARDWARE INSTALLATION

Before you begin, gather these supplies:

Computer system manual

DOS and other operating system installation disks or

Windows 95 startup disk

Operating system manual

Small Phillips screwdriver and flat-blade screwdriver

Create a Bootable DOS Disk

For Windows 3.1x and DOS users, you must have a bootable DOS

disk to install your new hard drive. Disk 1 of your standard DOS

installation disks is a bootable disk. If you don’t have DOS

installation disks, you can create a bootable disk if you have a

bootable C: drive.

1. Insert a blank disk into drive A.

2. Type format a:/s and press ENTER.

Create a Windows 95 Startup Disk

For Windows 95 users, you must have a bootable operatingdisk

before you install the new hard drive. If you don’t have a Windows

95 Startup disk, you can create one if you have a bootable C: drive.

1. Insert a blank disk into drive A.

2. From Windows 95, click My Computer, and then click Control

Panel.

3. Click Add/Remove Programs.

4. Select the Startup Disk tab.

5. Click Create Disk. Follow the onscreen prompts to create a

Windows 95 startup disk.

Back Up Existing Drives

Back up the data on your existing hard drive before installing your

new Western Digital hard drive. Save the data to floppy disks, tape

or other media. Most DOS versions include a backup utility. Consult

your operating system or utilities documentation for backup

procedures.

Handling Precautions

Western Digital products are designed to withstand normal handling

during unpacking and installation. Hard drives are typically damaged

because of electrostatic discharge (ESD), rough handling, or shock

and vibration. Be aware of the following precautions when

unpacking and installing your Western Digital hard drive.

Save your packing materials for the unlikelyevent that you need

to return the hard drive. Shipping your hard drive in anything

other than the original packaging materials may void your

warranty.

To avoid ESD problems, ground yourself by touching the metal

chassisof the computer before handling the hard drive.Articles of

clothing generate static electricity. Do not allow clothing to come

in direct contact with the hard drive or circuit board components.

Handle the hard drive by the sides only. Avoid touching the

circuit board components.

Do not drop the hard drive.

We recommend that you do not unpack the hard drive until you

are ready to install it. Once your Western Digital hard driveis

unpacked, place the drive on its antistatic bag on a clean, level

work area. Do not stack hard drives or stand the Western Digital

hard drive on its edge.

Do not remove the tape seal or any labels from the drive; the

warranty will be void.

Open Your Computer

1. Turn off your system.

2. Discharge static electricity by touching the metal chassis of the

computer.

3. Unplug your computer.

4. Remove the computer’s outside cover. Consult your computer

system manual for details. Be sure to keep all screws and other

parts together for reassembly.

Remove Existing Hard Drives

If replacing an existing drive, follow these instructions.

1. Disconnect the power cable and interface cable.

2.Remove screws andslide the hard drive out of the drive bay.

Handle the drive with care. You might need this drive if you have

difficulty installing the new drive.

Note: Do not scratch the sides of the hard drive; this will void your

warranty.

Set the Drive Jumpers

Western Digital is currently shipping hard drives with two types of

connectors. Your hard drive may have either a 6-pin or a 10-pin

connector. The first 6 pins on each of the jumper blocks are identical.

The additional four pins on the 10-pin connector are reserved for

future enhancements.

The Western Digital hard drive is factory set for single drive

installation with a jumper in the neutral storage position (across pins

5-3). For standard jumper settings, see Figure 1 on page 2.

Single Hard Drive Installation

If installing the Western Digital hard drive as the only hard drive in

your system, leave the jumper in the neutral storage position for

possible future use. Jumpers are not required for single hard drive

installations.

Dual Hard Drive Installation

If installing the Western Digital hard drive with an existing drive,

you must use a jumper to designate which drive is the master (C:),

and which is the slave (D:). We recommend using the new

Western Digital hard drive as the master.

If installing the Western Digital hard drive with a non-Western

Digital hard drive, obtain jumper configuration information from

your original drive manufacturer. Refer to the Troubleshooting section

for the phone numbers of non-Western Digital hard drive

manufacturers.

To designate the Western Digital hard drive as the master drive in

a two-drive system, place the jumper on pins 5-6.

To designate the Western Digital hard drive as the slave drive in a

two-drive system, place the jumper on pins 3-4.

To Install a Jumper

Carefully place the shunt over the two pinsspecified in Figure1.

Push the shunt into place until it is firmly seated against the base of

the jumper block.

Note: The master/slave setting is determined by the jumper configura-

tion, not by the order of the drive on the IDE cable.

Figure 1. Jumper Settings for Western Digital Hard Drives

79-850078-001 S0210 9-97 2

Mounting Hardware

Inspect the bay to see whether it is a 3.5-inch or 5.25-inch bay. The

Western Digital hard drive fits intoa 3.5-inch bay. If installing the

Western Digital hard drive in a 5.25-inch bay, you must install the

5.25-inch mounting hardware that is provided. You might also need

to install the system manufacturer’sdrive rails. Consult your

operating system manual for installation intoa 3.5-inch bay.

Installing the 5.25 Mounting Hardware

This step is not required for hard drive installations into a 3.5-inch

drive bay.

1. Gently place the hard drive horizontally (circuit board side down) on

top of the ESD bag placed on a flat, padded surface.

2. Attach the mounting brackets to the hard drive using the screws

provided. For proper grounding, be sure to use ALL FOUR

screws.

Drive Rails (Optional)

Some computer systems have 5.25-inch drive bays that require

unique slidingdrive rails tocomplete the hard drive installation.

Because each system manufacturer has a different type of drive rail,

rails are not included with Western Digital hard drives.

If your system requires drive rails, contact the computer system

manufacturer. The following list provides phone numbers for

common system manufacturers.

1. Thread the cable through the empty drive bay and slide in the

Western Digital hard drive.

2. Attach the end of the 40-pin interface cable to the 40-pin

connector on the back of the Western Digital hard drive. Match

pin socket 1 on the IDE cable (indicated by a color stripe on the

cable) to pin 1 on the Western Digital hard drive. See Figure 3.

3. Attach the computer system power supply cable to the 4-pin power

connector on the back of the Western Digital hard drive. The

4-pin connector is keyed to ensure proper insertion.

4. Single Installations: Attach the end of the 40-pin IDE cable from

the Western Digital hard drive to the IDE connector onthe

motherboard or controller card. Match pin socket 1 on the IDE

cable (indicated bya color stripeon the cable) to pin 1 on the

motherboardor controller card.

Dual Installations: Connect the two hard drives by using a

three-connector IDE interface cable. A three-connector IDE

interface cable is included in this package. Match the orientation

of pin socket 1 on the 40-pin three- connector IDE cable to pin 1

on the drive connector.

See Figure 3.

5. Mount the Western Digital hard drive in the drive bay using the

four mounting screws provided. For proper grounding, be sure to

use ALL FOUR screws.

If an extra power connector is not available, purchase a Y-adapter

from your computer dealer.

6. Check all cable connections. Replace the system cover, but don’t

screw it on yet. If you can’t get the new drive to work, you may

need to check the connections.

7. Plug in your computer. See the Software Installation section for

hard drive setup instructions.

Figure 2. 5.25-inch Mounting Hardware

Figure 3. Attaching IDE Cable to the Hard Drive

Tips:

Install single drives at the end of the 40-pin IDE cable. The

40-pin IDE cable should be no longer than 18 inches.

The master/slave is determined by jumper configuration, not

by the order of the drive on the cable.

79-850078-001 S0210 9-97 3

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.

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 receivedwith 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 softwaresuch as EZ-Drive is installed.

2.1 GB 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.

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.

79-850078-001 S0210 9-97 4

Compatibility: You can use EZ-Drive software with DOS 5.0 and

above, Windows 3.1x, Windows for Workgroups, Windows 95,

Windows NT, OS/2 2.1x, and OS/2 Warp.

You cannot use EZ-Drive with Novell NetWare or Unix.

Data Compression Software: EZ-Drive is compatible with Stacker,

Drivespace, and Doublespace disk compression utilities. Other data

compression software may not be compatible. Always back up your

data before using any data compression software.

Hard Disk Device Drivers: Products that use their own harddisk

device drivers, such as third-party disk controllers, may not be

compatible with EZ-Drive.

Memory Managers: EZ-Drive is fully compatible with the standard

memory managers that come with DOS and Windows. However,

EZ-Drive loads in conventional memory and may not be compatible

with some third-party memory managers.

Ontrack Disk Manager and EZ-Drive: Ontrack Disk Manager and

EZ-Drive cannot co-exist in the same system. If your existing drive

has Ontrack Disk Manager installed and multiple partitions, you

cannot install EZ-Drive. We recommend using Ontrack Disk

Manager to set up thenew hard drive.

If your existing drive has Ontrack Disk Manager installed and only

one partition, you can either use EZ-Drive toconvert the Ontrack

Disk Manager partition or use Ontrack Disk Manager to set up the

new drive. During installation, EZ-Drive detects Ontrack Disk

Manager and prompts you to convert the partition to an EZ-Drive

partition. If you do, EZ-Drive converts the Ontrack Disk Manager

partition to an EZ-Drive partition.

Even though EZ-Drive can convert your Ontrack Disk Manager

partition to an EZ-Drive partition without data loss, Western Digital

recommends that you back up your data before selecting this option.

Note: EZ-Drive can convert single Ontrack Disk Manager partitions

only.It cannot convert multiple OntrackDisk Manager Partitions.

Using EZ-Drive Software

Follow these instructions to partition and format your new hard

drive. If your system does not support the full capacity of the hard

drive, EZ-Drive installs special code in the boot sector of the hard

drive to overcome your BIOS limitations.

If your system does support the full capacity of your hard drive,

EZ-Drive will only partition and format your hard drive. It will not

install code on your boot sector.

1. After you complete CMOS setup, insert a bootable DOS or

Windows 95 startup disk in drive A.

2. Press CTRL+ALT+DEL to reboot your system.

3. Insert the EZ-Drive disk in drive A. At the A: prompt, type ez and

press ENTER.

instructions and procedures.

TROUBLESHOOTING

2.5 GB or Larger Hard Drives

If you install a 2.5 GB or larger hard drive and your system locks up

on initial boot, read the instructions in this section.

The 2.5 GBor larger hard drives have more than 4095 cylinders.

With some systems, the BIOS CANNOT properly recognize hard

drives that have more than 4095 cylinders.

You know if your system BIOS has this limitation after installing the

drive. On the initial boot your system may lock up or show a much

smaller drive capacity. If your system locks up, follow the instructions

below. If your system reports a much smaller drive capacity, follow

the instructions outlined in the Software Installation section.

If your system does not respond (locks up)after two minutes, follow

these steps:

79-850078-001 S0210 9-97 5

1. Turn your system power off, check the IDE interface and power

supply cables.

2. Check jumper settings.

3. Turn on your system power.

4. Try to enter your CMOS setup, and set the drive type to auto.

If your system still doesn’t respond, you may have a system BIOS

that doesn’t support drives with more than 4095 cylinders. If this is

the case, these solutions are available:

1. Use EZ-Drive.

If the system locks up before you can enter CMOS, you may need

to turn off your system power and disconnect the IDE cable from

the system to access your CMOS setup.

Enter your CMOS setup. Refer to your system manual for

instructions.

Select the Hard Disk Type option for the new Western Digital

hard drive. Select a user defined drive type and enter: 1023x16x63.

Reconnect the IDE cable to the system.

The new settings allow your system to boot so that you can install

EZ-Drive to accessthe full drive capacity.

– OR –

If you don’t have a user defined drive type, follow step 2 or 3 below to

change the parameters reported to the BIOS. In the future, if you

move this drive to another system, you must put the jumper back

to the standard position.

2. Rejumper the drive as shown in Figure 4 on page 6, and install

EZ-Drive. If you use the alternate jumper settings, you must

install EZ-Drive.

Note: These special jumper settings WILLNOT work for OS/2 Warp,

Novell NetWare, or Unix.

– OR –

3. Upgrade your BIOS.

A properly upgraded BIOS will support the drive. Contact your

system manufacturer. See page 3 for a list of common system

manufacturers and page 7 for BIOSsources and their phone

numbers.

Figure 4. Jumper Settings for 2.5 GB or Larger

Hard Drives (Used to overcome the BIOS limitations described in this section.)

Frequently Asked Questions

A short list follows with common questions along and solutions.

Q: I get the message “HDD Controller Failure” after installing my

Western Digital hard drive.

A: This common message may appear when you first boot the

system after installing the hard drive. Press F1 to continue. If the

message continues to display, retrace the steps outlined for CMOS

setup, cabling, and jumper configuration.

Make sure to follow the installation instructions correctly. Then

followthe instructions for using EZ-Drive or FDISK and FORMAT

to install the operating system.

Q: Do I need to run FDISK and FORMAT ?

A: Not if you installed EZ-Drive software.

Q. Whatis a megabyte?

A: Harddrive suppliers define a decimal megabyte as 1,000,000

bytes (106 ). Alternatively, a binary megabyte is defined as 1,048,576

(220 ). This is why different utilities will display different numbers of

megabytes available for the same drive.Thevalues inTable 1 usethe

following megabyte definitions:

Capacity Megabytes

CMOS (MB) binary megabytes

CHKDSK (MB) decimal megabytes

Q: Do I have to do anything to my original hard drive when adding

yours to it?

A: Yes, one hard drive must be designated as a master, and the other

as a slave. We recommend that you designate the newdrive asyour

master. For non-Western Digital hard drives, consult your original

hard drive documentation for master/slave jumper settings. See

Non-Western Digital Drives on this page. If the original hard drive

uses disk compression software, consult the disk compression

documentation before adding another drive.

Q: Whatshould I check if my system will not startafter I turn on

the power?

A: Ensure that:

1. The IDE controller card, if installed, is properly seated and

connected.

2. The connectionsat bothends ofthe hard drive cable are secure

and correctly oriented.

3. The jumper selections on your hard drive(s) are set correctly for

your installation.

4. The drive is connected to the computer powersupply via the 4-pin

power connector.

Q: I used FDISK and FORMAT to set up my newhard drive. Now, I

can’t boot DOS from my newly installed hard drive or access the

hard drive after I’ve completed the software installation.

A: Check the system to make sure:

1. You entered the correct hard drive parameters during the system

setup procedure.

79-850078-001 S0210 9-97 7

2. Some CMOS Setup utilities might have a boot sequence option. If

yours does, verify that the boot sequence is A: then C:. Not all

CMOS setup utilities have this option.

3. You correctly partitioned (via the operating system FDISK utility)

and formatted (via the operating system FORMAT utility) your

newly installed hard drive.

4. You made your primary drive bootable (formatted with /S option).

5. During the FDISK procedure you marked your bootable partition

active.

Q: Mydrive will not spin up, or it spins down after a few seconds.

A: Ensure that:

1. Your power connector is secure and working properly.

2. The orientation of pin socket 1 on the 40-pin IDE cable matches pin

1 on the connector.

3. The drive type in your CMOS setup is correct.

Q: I don’tsee the full capacityof my hard drive when installing

DOS.

A: Two issues affect the installation of yourhard drive: 1) some

systems do not properly recognize hard drives that have more than

4095 cylinders (drives larger than 2.1 GB); 2) most system BIOS

dated before 1994 don’t recognize drives greater than 528 MB.To

overcome this limitation, either install EZ-Drive or upgrade your

system BIOS. The following list provides the phone numbers for

common BIOS sources.

BIOS Sources:

Micro Firmware

(Phoenix BIOS only) (405) 321-8333

Phoenix (617) 551-4000

Unicore (508) 686-6468

If you installed EZ-Drive and then incorrectly booted to your DOS

installation disks, you may have accidentally used DOS to overwrite

your EZ-Drive partitions. You need to use FDISK to delete all

partitions, and then re-install EZ-Drive. Be sure to follow the

instructions outlined in the section Installing an Operating System

from Disk on page 5

Q: The reported capacity of my hard drive is MUCH smaller than

Table 1 shows it should be.

A: Your system BIOS improperly handles hard drives that report

greater than 1024 cylinders. Use the supplied installation software to

get the full capacity of your drive.

Q: How much memory does EZ-Drive use?

A: 5 KB.

Q: How can I get 32-bitdisk access in Windows?

A: Use the 32-bit disk access driver included on the software

installation disk. Install the driver by running the EZ-Drive’s

SETUP.EXE program, or use the DMCFIG program if you have

Ontrack Disk Manager.

Q: I am installing a new Western Digital drive onto a second IDE

controller card (secondary port). Howdo I jumper it?

A: Refer to the standard jumper options shown in Figure 1. If it’s the

only drive onthe cable,jumper it as single.If the drive is paired with

another IDE device, jumper it as master or slave.

Q: Should I partition my hard drive?

Caution: Repartitioning an existing drive destroys all the data. If

repartitioning an existing drive, be sure to create a backup first.

If your hard drive is 2.5 GB or larger, you must create multiple

partitions.

Western Digital doesnot have a recommendation for the optimal

number of partitions. The following information will help you make

the decision.

EZ-Drive and FDISK utilities allow you to divide your drive into

multiple partitionsthat function as separate drives.

In DOS, every file that is stored gets at least one allocation unit

(cluster), regardless of the file size. The size of the cluster increases

with the size of the partition. For example, if you have a 1024 MB

partition, the cluster size is 32 KB. This means that even a 62-byte

batch file consumes 32 KB of storage space. A typical mix of

application and data files can include thousands of files. If each file

contains a few kilobytes of wasted space, this can add up to several

megabytes of wasted space.

The onlyway to reduce the cluster size isto reduce the partition size.

The breakdown for DOS5.0 and above follows:

FDISK Partition Size* Cluster Size

0 - 127 MB 2 KB

128-255 MB 4 KB

256-511 MB 8 KB

512 - 1023MB 16 KB

1024 - 2047 MB 32 KB

* FDISK reports binary megabytes (1,048,576 bytes), not decimal megabytes

(1,000,000 bytes). All numbers above are shown in binary megabytes.

Note: The maximum partition that can be created in DOS is 2048 MB.

Q: Will my drive work with Windows 95?

A: Yes. Your drive has been thoroughly tested in the Western Digital

FIT Lab and is compatible with Windows 95.

Q: I have a 2.5 GBor larger drive. Can I create one partition only?

A: No. DOS has a 2.1 GB partition limitation. You must have at

least two partitions to access the full capacity of your drive.

Q: Whatwill happen if I install EZ-Drive on a hard drive that has

Ontrack Disk Manager?

A: EZ-Drive and Ontrack Disk Manager cannot coexist in the same

system.Ifthe existing hard drive has only one partition and Ontrack

Disk Manager already installed, EZ-Drive converts the Ontrack Disk

Manager partition to an EZ-Drive partition. Back up your hard

drive before installing EZ-Drive. If the existing hard drive has

multiple partitions and Ontrack Disk Manager installed, EZ-Drive

will not install. Use Ontrack Disk Manager to set upthe new hard

drive.

Q: Can I install Windows NT 3.5x, OS/2 2.1x or OS/2 Warp on my

drive that originally was installed with EZ-Drive?

A: Yes, but you must disable floppy boot protectionbefore installing
