Jumper settings for Western Digital EIDE drives.
Note: this information is from the western digital web site and is only
intended to be a copy of the information as was found when the drives were
introduced. The WD site has the most up to date information
Two different protocols can be used for jumpering EIDE devices, including
disk drives. One is the master-slave relationship. With this protocol, one
device is jumpered as master and the other is jumpered as slave. The second
protocol is cable select. With this protocol, both devices are jumpered as
cable select and their position on the cable dictates which is the master and
which is the slave. The end device is master while the device on the middle of
the cable is slave. You can use either of these protocols but you cannot mix
them on the same data cable. Both methods refer to having multiple devices
attached to the same IDE cable and have options for single drive installations
(only 1 drive installed on the system).
A diagram of the jumper settings appears below:

Cable Select Configuration Options for PC Systems:
If you have determined that your system and all other IDE devices support
Cable Select, please use the following information to connect your IDE drive.
The jumper should be on pins 1-2.
Installing the new drive as the only drive in the system:
If you are connecting your drive as the only IDE drive on the cable, then
there is no need to change the jumper pin on the drive. Simply connect the
drive to the black connector at the end of the cable.
Installing the new drive as the primary (Master) drive:
If you are connecting your drive as the primary drive on the cable with
another IDE drive, there is no need to change the jumper pin on the drive.
Jumper the other IDE drive as Cable Select. Connect the drive to the black
connector at the end of the cable for the system and the other IDE drive to
the gray connector located at the middle of the cable.
Installing the new drive as the secondary (slave) drive:
If you are connecting your drive as the secondary drive on the cable with
another IDE drive, there is no need to change the jumper pin on the drive.
Jumper the other IDE drive as Cable Select. Connect the drive to the gray
connector in the middle of the cable and other IDE drive to the black
connector located at the end of the cable
Master/Slave Configuration Options for PC Systems:
Installing the new drive as the only drive in the system:
If you are connecting your drive as the only IDE device on the cable, then
move the jumper shunt on the drive from pins 1 & 2 to pins 4 & 6. Once
the jumpers have been configured, connect the drive to the black connector at
the end of the cable.
Installing the new drive as the primary (Master) drive:
If you are connecting your drive as the Master drive on the cable with another
IDE device, move the jumper shunt on the drive from pins 1 & 2 to pins 5
& 6. Then configure the jumper on the other IDE device as Slave. Connect
the drive to the black connector at the end of the cable, and the other IDE
device to the gray connector located at the middle of the cable.
Installing the new drive as the secondary (Slave) drive:
If connecting your drive as the secondary drive on the cable with another IDE
device, move the jumper shunt on the drive from pins 1 & 2 to pins 3 &
4. Then configure the jumper on the other IDE device as Master. Connect the
drive to the gray connector at the middle of the cable, and the other IDE
device to the black connector located at the end of the cable
