I have bought a brand new 500gb Seagate Barracuda Hard drive and a New Icy box enclosure for it. After putting it together and plugging it in to the computer, It displays a message saying device not recognised by the computer and that it may have malfunctioned (but it is new). I guessed i would need to partition and format it so i went to disk management but it is not listed!??? It is also not in my computer however it is in device management but has a yellow explanation mark. which reads (unknown device) and the description reads Windows has stopped this device because it has reported problems. (Code 43). Please help!!!
