First in the Olympic Long Jumper.....
WD SATA 2 drives don't have a Jumper to limit them to 150Gbs
Seagate drives come with a factory installed jumper, which limits them to the 150 Gbs (SATA 1 ) standard. They need to have the jumper removed to run at SATA 2 (300 Gbs) standard. In either case, you should likely have to do nothing to have the drive recognized.
