Note: WDC Carvair Black 6 Gbps drives require jumpers on pins 5-6 to be recognized as SATA-II

Guys,

Just a note. The newer Carvair Black 6.0 Gbps drives do not come with jumpers. However, in order for the drives to be recognized as SATA-II on some controllers (the default is SATA-I at 1.5 Gbps), you must install jumpers on pins 5-6 for the drives to initialize at 3.0 Gbps:

  Without the jumpers, the drives are limited to SATA-I
