How to set jumpers on a Hard disk

Setting the Jumpers on a seagate hard drive

Cable Select. The drive is configured at the factory for a cable select setting. This allows the drive to assume the proper role of master or slave based on the connector used on the cable (see the UltraATA cable figure below). For the cable select setting to work properly, the cables you are using must support the cable select feature. Current UltraATA cables with the 3 colored connectors do support this feature.

Master or single drive. If you are installing your Seagate hard drive as the only drive in the system or if it will be the primary boot drive for the system, the jumper should be set on pins 7 and 8.

Drive as slave. If you are installing the drive as an additional drive in your system, the drive should be set as slave by removing all jumpers. Remember to confirm that the original drive is set to a master position (If the limit capacity jumper is required for your installation it will need to remain in place).

Drive as master with a non-ATA-compatible slave (SeagateĀ® drives only). Set a jumper on pins 5 and 6 and a jumper on pins 7 and 8. Use this jumper setting only if the drive does not work as a master.

Cable Select Configuration Options for PC Systems:


If you have determined that your system and all other IDE devices support and are using Cable Select, please use the following information to connect your IDE drive. The jumper should always be on pins B-D for Cable Select installations.

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, please ensure that a jumper is connected to pins B-D on the 2.5″ drive. Simply connect the drive to the end of the cable.

Installing the new drive as the primary (Master) drive:
If you are connecting your drive as the primary (Master) drive on the cable with another IDE drive, please ensure that a jumper is connected to pins B-D on the 2.5″ drive. Please ensure that the second (Slave) IDE drive is jumpered as Cable Select as well. Connect the primary (Master) 2.5″ drive to the end of the cable and the second (Slave) drive to the middle connector of the cable.

Installing the new drive as the secondary (Slave) drive:
If you are connecting your drive as the secondary (Slave) drive on the cable with another IDE drive, please ensure that a jumper is connected to pins B-D on the 2.5″ drive. Connect the 2.5″ drive to the middle of the cable and other (Master) drive to 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, no jumper is needed on the 2.5″ drive. Connect the 2.5″ drive to 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, no jumper is needed on the 2.5″ drive. Ensure to configure the jumper on the secondary (Slave) IDE device as Slave. Connect the primary (Master) 2.5″ drive to the end of the cable, and the secondary (Slave) device to 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, please ensure that a jumper is connected to pins A-B on the 2.5″ drive. Configure the jumper on the primary IDE device as Master. Connect the 2.5″ (Slave) drive to the middle of the cable, and the Master IDE device to the end of the cable.
