Jumper settings for Seagate ATA hard drives. Note: This figure depicts the jumper settings for recent Seagate ATA drive families above 20 GBytes. If you have an older drive please visit our Technical Library and find your model number for details on jumper configuration.	Jumper settings for Maxtor ATA hard drives.

Setting the Jumpers

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 (Seagate® 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.

Limit drive capacity/Capacity Limitation Jumper (CLJ). Use this when either you start up your computer and see the message, "Hard disc drive controller failure", your computer does not recognize your newly installed hard drive, or your system stops responding during the boot process after installing this new drive. If this jumper is required, your system cannot support a drive this large and can be updated with a PCI controller card.

Additional information for Seagate products

These are the different jumper setting configurations you may encounter using the Limit Capacity Jumper Setting:

Single Master with Limit Capacity

[ :] : : [:]

Slave with Limit Capacity

: : : [:]

Master with Non-ATA Compatible Slave
This is usually ATAPI devices like CD-ROMs plus Limit Capacity

[:] [:] : [:]

This occurs in some computers that do not support high-capacity drives. To address this problem, install the capacity-limiting jumper on your new hard drive, as shown in the jumper setting illustrations above (this will not affect the storage capacity of your drive).

UltraATA Cables

We recommend the use of newer UltraATA 66/100 cables to achieve the best performance from your new Seagate hard drive. These UltraATA cables have 3 colored connectors, each connector has a specific purpose. Be sure to plug the correct connector into the correct device.

• The blue connector is for your host bus adapter (using a connector on your motherboard).
• The black connector at the other end is for your master device, usually the hard drive you boot from.
• The gray connector is for an optional slave device if you have a second hard drive.

Other devices like CD-ROM drives, tape drives and CD burners are usually plugged into a separate cable which also connects to the motherboard.
