be care full with the 6g sata ports on most mb there be two sets of them. the intel/amd chipset and a 3 party chipset. most times the 3 party chipset will be turned off. the standard 3g blue ports. also in the bios check the sata port settings. there can be raid..ide or achi setting. you want set the ports to achi. if no achi then ide..not raid. alos most of the new mb with gui bios show the drive up under boot devices and not under sata anymore..
