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 access the 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 WILL NOT work for OS/2 Warp,
Novell NetWare, or Unix.

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
numbers.

MUST install EZ-Drive.
