Hallo, I´ve bought a new board: ASROCK Extreme3 and I change all the HD and SDD to the new system. The problem is now: this hard drive (only the HD502HJ), will not be recognised from the new Bios when the Sata Cable is pluged in. It is like the HD didn´t get an impuls to work. So, SATA cable out and the HD runs. And in this moment I pull the cable in and the Bios recognised the HD. Shut down the computer and I have to do all the steps aganin. A Problem of the mainboard or of the harddrive? And does anyone has a tip?
