Look like the Slave/Master Jumpers dont they, guess left overs from that era or for factory testing.
Well... Quote from another site:
A sticker on the disk explains that pins 3-4 are enabling “Power Management”. But what does this mean? We could not find any further explanation in the Raptor’s technical documentation for “Power Management.” In Western Digital’s knowledge base we found this: "The Raptor has a jumper block located next to the ATA power connector (see image below). There is generally no need to change the default jumper setting in order to use the drive. The only use of this jumper block is to enable or disable power management for the drive. The drives ship in the default position with the shunt on pins 1-2 (disabled). Alternately, the jumper can be removed completely with the same result. Placing the shunt on pins 3-4 (enabled), designates that the drive will power-up in standby mode. For most users the default position should be used."
The problem is that putting the jumper on 3-4 does not have any impact. The other pins are without function anyway. They are remnants from PATA times and now useless. The story became even more a mystery when we found out that when running 2 Raptors in RAID 0 anything else than the jumper on 1-2 would not let us boot from the RAID 0 array. We recommend keeping the jumper on the default setting 1-2.
