The following are general descriptions for the jumper settings on Samsung ATA/IDE drives. To know the specific jumper setting for your particular model, please see the drive label.
Master or single drive:
If you are installing your Samsung 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 as Cable Select. If you are connecting the drive to an older system that has a pre-UDMA Mode 3 ATA controller, or you are connecting this to a cable with a slave device that doesn’t have a cable select jumper setting, jumper the drive as Master.
If you are installing the drive as an additional drive in your system, the drive should be set as Cable Select. If you are connecting the drive to an older system that has a pre-UDMA Mode 3 ATA controller, or you are connecting this to a cable with a master device that does not have a cable select jumper setting, jumper the drive as Slave.
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. With the Cable Select jumper set, the BIOS determines whether a drive is a master or a slave by its position on the UltraATA cable. If the drive is jumpered as cable select and is connected to the black connector on the end of the cable, it is recognized as the master drive for that ATA controller. If the drive is jumpered as cable select and is connected to the grey connector on the middle of the cable, it is recognized as the slave drive for that ATA controller.
Limit capacity jumper:
This option may be required, in conjunction with the master, slave, or cable select jumper position, if the system the drive is being installing into does not support the full capacity of the drive. It will limit the drive to 32 GB.
Use it on computers manufactured before November 1998 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 you want to be able to use more than 32 GB of your hard drive, Seagate recommends you update your motherboard or install an UltraATA PCI card in your computer and remove the limit capacity jumper.
Seagate recommends the use of newer UltraATA cables to achieve the best performance from ATA hard drives. 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.
