Hard drive does not show up in either 'My Computer' or in device manager. Im quite new to building my own pc. I built this one from the ground up basically by myself with no problems. Ive taught myself everything i do know and this is beyond my knowledge. Is there anything i could have done wrong? when i restart the pc it shows up as S.M.A.R.T Error. or something along those lines. Windows 7 64 bit, any other information needed will be provided. Any help would be awesome! Thanks in advance.
