HARDWARE INSTALLATION

Handling Precautions

Before you begin, gather these supplies:

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.

Computer system manual

DOS and other operating system installation disks or

Windows 95 startup disk

Operating system manual

Save your packing materials for the unlikely event that you need

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

other than the original packaging materials may void your

warranty.

Small Phillips screwdriver and flat-blade screwdriver

Create a Bootable DOS Disk

To avoid ESD problems, ground yourself by touching the metal

chassis of 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.

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.

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

circuit board components.

1. Insert a blank disk into drive A.

Do not drop the hard drive.

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

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

are ready to install it. Once your Western Digital hard drive is

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.

Create a Windows 95 Startup Disk

For Windows 95 users, you must have a bootable operating disk

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.

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

warranty will be void.

1. Insert a blank disk into drive A.

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

Panel.

Open Your Computer

3. Click Add/Remove Programs.

4. Select the Startup Disk tab.

1. Turn off your system.

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

computer.

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

Windows 95 startup disk.

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.

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.

Remove Existing Hard Drives

If replacing an existing drive, follow these instructions.

1. Disconnect the power cable and interface cable.

2. Remove screws and slide 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.

Mounting Hardware

Install Your New Hard Drive

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

Western Digital hard drive fits into a 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’s drive rails. Consult your

operating system manual for installation into a 3.5-inch bay.

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.

Installing the 5.25 Mounting Hardware

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.

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.

Figure 3. Attaching IDE Cable to the Hard Drive

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

the Western Digital hard drive to the IDE connector on the

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

cable (indicated by a color stripe on the cable) to pin 1 on the

Figure 2. 5.25-inch Mounting Hardware

Drive Rails (Optional)

motherboard or controller card.

Some computer systems have 5.25-inch drive bays that require

unique sliding drive rails to complete the hard drive installation.

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

rails are not included with Western Digital hard drives.

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.

If your system requires drive rails, contact the computer system

manufacturer. The following list provides phone numbers for

common system manufacturers.

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.

SOFTWARE INSTALLATION

Partitioning and Formatting

Before using the new hard drive, you need to configure your system

BIOS (CMOS Setup program) and partition and format the hard

drive.

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.

CMOS Setup

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

2. Use the DOS utilities FDISK and FORMAT.

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.

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.

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.

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.

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.

EZ-Drive 8.x Software Overview

EZ-Drive 8.x software is included with the Western Digital hard

drive to help you:

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.

Partition and format your new hard drive.

Overcome the 528 MB barrier.

Tips:

Overcome the 2.1 GB barrier.

If your CMOS setup does not have an auto config drive type,

try selecting Type 01. Then install EZ-Drive.

If you did not receive the EZ-Drive software, you can download it

from our web site at www.wdc.com.

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.

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.

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.

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.

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.

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.

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.

6. After EZ-Drive detects the drive, the following message displays if

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

EZ-Drive must control this drive to access the full capacity

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

Press Y to continue installation.

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.

7. EZ-Drive formats the drive now. Follow the instructions onscreen,

and when prompted, insert a DOS disk.

8. EZ-Drive has successfully set up your hard drive. Remove any disk

ESC

from the floppy drive and press

to exit and restart the system.

Hard Disk Device Drivers: Products that use their own hard disk

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

compatible with EZ-Drive.

Your hard drive is now partitioned and formatted.

Installing an Operating System from Disk

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.

If you installed EZ-Drive on the hard drive, you must follow the

steps below to install DOS 5.0 and above, Windows 3.1x, Windows

for Workgroups, Windows 95, Windows NT, OS/2 2.1x, and OS/2

Warp from disk. If you did not install EZ-Drive, or used it only to

partition and format your hard drive, see your DOS manual for

installation instructions.

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 the new hard drive.

Caution: If you do not install DOS exactly as described below, the

DOS setup routine reformats the hard drive to less than the full

capacity.

If your existing drive has Ontrack Disk Manager installed and only

one partition, you can either use EZ-Drive to convert 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.

1. Remove any disk from the floppy drive.

2. Press CTRL+ALT+DEL to reboot the system. The following message

displays if EZ-Drive is installed on your hard drive.

EZ-Drive: Initializing. . .

EZ-Drive: Hold the

from a floppy.

CTRL

key down for Status Screen or to boot

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.

CTRL

3. Press and hold down the

key. A status screen displays.

4. Read the screen prompt and type A.

ENTER

5. Insert the DOS installation disk 1 into drive A. Press

Follow the prompts to complete installation.

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

only. It cannot convert multiple Ontrack Disk Manager Partitions.

USING THE DRIVE

Using EZ-Drive Software

It is extremely important to regularly back up the data on your

hard drive. In the event of data damage or loss, a backup ensures

successful recovery.

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.

Consult your operating system documentation for backup

instructions and procedures.

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.

TROUBLESHOOTING

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

Windows 95 startup disk in drive A.

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.

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

The 2.5 GB or larger hard drives have more than 4095 cylinders.

drives that have more than 4095 cylinders.

ENTER

press

4. The Micro House EZ-Drive license agreement displays.

Press ENTER to start the installation.

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.

CAUTION: Installing EZ-Drive on any drive that contains software

and data will result in the erasure of all software and data on that

drive.

Figure 4. Jumper Settings for 2.5 GB or Larger

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

Note: Use these jumper settings only if you encounter the specific BIOS limitation described in this section. When using these jumper settings, you

MUST install EZ-Drive.

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

supply cables.

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

EZ-Drive to access the full drive capacity.

2. Check jumper settings.

– OR –

3. Turn on your system power.

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.

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:

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.

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.

Note: These special jumper settings WILL NOT work for OS/2 Warp,

Novell NetWare, or Unix.

– OR –

Enter your CMOS setup. Refer to your system manual for

instructions.

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 BIOS sources and their phone

UNINSTALLING EZ-DRIVE

Frequently Asked Questions

This option removes EZ-Drive, and returns control of the drive to

your system BIOS.

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.

Note: Before uninstalling EZ-Drive, make sure that you have properly

configured the BIOS to recognize the full drive capacity.

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.

A: Hard drive 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. The values in Table 1 use the

following megabyte definitions:

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

as a slave. We recommend that you designate the new drive as your

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.

General

This section lists procedures to help resolve problems that you may

encounter when installing the Western Digital hard drive.

Refer to your system documentation to be sure that you followed

the setup procedures correctly.

Q: What should I check if my system will not start after I turn on

the power?

Make sure that you partitioned and formatted the EIDE drive and

any additional drive with the EZ-Drive or other installation

software or DOS FDISK and FORMAT utilities. (If you are

making this drive bootable, remember to specify the /S

parameter.) Refer to your operating system documentation to

check these procedures.

A: Ensure that:

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

connected.

2. The connections at both ends of the hard drive cable are secure

and correctly oriented.

If using DOS 3.3 and above, be certain to make one partition active

during formatting.

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

your installation.

Check the physical installation of your system to make sure that:

- Jumper selections on the drive are correct for your installation.

- Cables are correctly connected and seated.

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

power connector.

Q: I used FDISK and FORMAT to set up my new hard 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.

- Adapter card, if required, is properly seated, connected, and con-

figured.

A: Check the system to make sure:

- Power is properly connected to your system and the system is

plugged in.

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

setup procedure.

Download from Www.Somanuals.com. All Manuals Search And Download.

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.

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

controller card (secondary port). How do I jumper it?

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

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

another IDE device, jumper it as master or slave.

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).

Q: Should I partition my hard drive?

5. During the FDISK procedure you marked your bootable partition

active.

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

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

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

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

partitions.

A: Ensure that:

Western Digital does not have a recommendation for the optimal

number of partitions. The following information will help you make

the decision.

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.

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

multiple partitions that function as separate drives.

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

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.

Q: I don’t see the full capacity of my hard drive when installing

DOS.

A: Two issues affect the installation of your hard 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.

The only way to reduce the cluster size is to reduce the partition size.

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

* 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: 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: I have a 2.5 GB or 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: How much memory does EZ-Drive use?

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

Ontrack Disk Manager?

A: 5 KB.

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

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

system. If the 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 up the new hard

drive.

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.
