2. Set the Jumpers

WD EIDE hard drives have a 10-pin jumper block located next to the
40-pin IDE connector on the hard drive. Jumper the drive according to
your desired configuration (i.e., Cable Select, Master/Slave, or Single).
Refer to the illustration on the left (Figure 1) for reference.
A. Cable Select
Cable Select is the default setting for WD EIDE hard drives and
requires a standard 40-pin, 80-conductor cable (not included). If your
system supports Cable Select, there is no need to reposition the
jumper shunt on the drive. If you are installing your new WD hard drive
with an existing IDE drive on the cable, make sure that the other drive
is also jumpered as Cable Select. If your system does not support
Cable Select or if you are uncertain, use the Single or Master/Slave
configuration.
Note: Cable Select mode is not supported by Macintosh's built-in
IDE/ATA controller. You must use the Master/Slave jumper setting.
B. Standard Jumper Settings (Master/Slave or Single
Configuration)
1. If installing your new WD hard drive as the only device on the cable,
use the Single setting (no jumper shunt required).
2. If installing your new WD hard drive as the Master device on the
cable with two IDE drives, use the Master setting.
3. If installing your new WD hard drive as a secondary device on the
cable, use the Slave setting.

3. Install the Hard Drive

Important: Your new WD hard drive must be installed using a
standard 40-pin, 80-conductor IDE interface cable.
Note: Installation instructions will vary depending on your drive
configuration. Carefully follow the appropriate procedure that
corresponds to your drive configuration.
1. If installing the hard drive as the only device on the cable, connect
the black connector of the IDE interface cable to the drive and the
blue end of the cable to the IDE connector on the motherboard.
Proceed to step 3.
2. If installing two drives on the same IDE cable,
a. Jumper the bootable drive as Master and the other drive as Slave;
then connect the Master drive to the black connector of the IDE
interface cable and the Slave drive to the gray connector.
b. Connect the blue end of the IDE interface cable to the IDE
connector on the motherboard (Figure 2).
3. Attach the power supply cable to the 4-pin power connector on the
drive (Figure 3).
4. Slide the hard drive into an available 3.5-inch drive bay and secure
the drive with the four mounting screws provided (two on each
side). For proper grounding, use screws in the hole positions as
shown (Figure 4).
5. Verify all cable connections. Replace and secure the system cover.
Reconnect the power cord and power on the computer.
