[arch-general] 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: 13:23 nirvana:~> sudo dmesg | grep ata <snip> [ 1.363358] ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1.370543] ata1.00: ATA-8: WDC WD1002FAEX-00Z3A0, 05.01D05, max UDMA/133 [ 1.372815] ata1.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 0/32) [ 1.380018] ata3: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1.386960] ata3.00: ATA-8: ST3750528AS, CC35, max UDMA/133 [ 1.389290] ata3.00: 1465149168 sectors, multi 16: LBA48 NCQ (depth 0/32) [ 1.389303] ata1.00: configured for UDMA/133 [ 1.406937] ata3.00: configured for UDMA/133 [ 1.853354] ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1.860937] ata2.00: ATA-8: WDC WD1002FAEX-00Z3A0, 05.01D05, max UDMA/133 [ 1.863299] ata2.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 0/32) [ 1.877002] ata2.00: configured for UDMA/133 Without the jumpers, the drives are limited to SATA-I -- David C.

Without the jumpers, the drives are limited to SATA-I
I'd say the manufacturer must have had some good reason to ship the drives configured like that and without a jumper. I'd let the drives operate as they came from the factory if you don't need the extra bandwidth of a faster interface (probably for most use cases you can't tell the difference). -- Mauro Santos

Yes, probably to save money on support calls. http://wdc.custhelp.com/app/answers/detail/search/1/a_id/5387#jumper Back when SATA-II came out some Seagate drive odels where not detected by old VIA SATA chips. The solution was to force the drive into the proper SATA mode by jumpers.
