Jumper settings for Seagate SATA hard drives.
Where and why to place a jumper on Seagate Serial ATA drives.
Serial ATA interface disk drives are designed for easy installation. It is not necessary to set any jumpers, terminators, or other settings on this drive for proper operation. The jumper block adjacent to the SATA interface connector on SATA 150MB/s drives is for factory use only. The jumper block adjacent to the SATA interface connector on SATA 300MB/s drives can be used to force the drive into SATA 150MB/s mode for use with older SATA controllers that only work with SATA 150MB/s drives.
With a Serial ATA interface, each disk drive has its own cable that connects directly to a Serial ATA host adapter or a Serial ATA port on your motherboard. Unlike Parallel ATA, there is no master-slave relationship between drives that use a Serial ATA interface.
You can use a Serial ATA drive in the same system with Parallel ATA drives as long as both interfaces are supported on the motherboard or with a host adapter. This makes it easy to add Serial ATA compatibility to your existing system without removing existing Parallel ATA disk drives.
