Hello good people, to see you explain my problem, I have a motherboard Asrock p67 extreme 6 with an i7-2600K, 4x4GB G.Skill, etc ... and a WD Caviar Greenhard drive. This hard drive is pretty seedy, 500gb. 32MB cache. SATA puts it logically, but not if it will be SATA1, SATA2 or SATA3 .... The problem comes when you install windows 7 on the aforementioned hard drive, I get an error. He says that the BIOS does not recognize but can not be corrupted.
