It is not necessary to set any terminators or other settings on this drive for proper operation. The jumper block adjacent to the SATA interface connector on SATA 150MB/sec drives is for factory use only. The jumper block adjacent to the SATA interface connector on SATA 300MB/sec drives can be used to force the drive into SATA 150MB/sec mode for use with older SATA controllers that only work with SATA 150MB/sec drives.

Each drive on the serial ATA interface connects in a point-to-point configuration with the serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports. This means both drives behave as if they are Device 0 (master) devices. Each drive has its own cable.
The jumper position to force the drive to SATA 1 speed (150 MB/sec) differs between Seagate drives and Maxtor drives. For the purposes of telling them apart, simply note the model number of the drive. If it begins with "ST" or "STM", see the jumper configuration for Seagate drives below. If any other model number, see the Maxtor model configuration.

Your serial ATA host adapter may provide master/slave emulation options. See your host adapter documentation for details.
