Ive had my USB Hard drive for almost over a year now. Seagate Freeagent Go 320GB. I use it for me wii. This is the second time it malfunctioned. At first is wasnt being recognized, so i bought a new enclosure an d put it on. It worked for a while and two days ago in messed up again. Now it wont Power on AT ALL. In the computer or the wii. Is it fried or what? It has a small power socket on the side. Is the USB not suppling enough power? do i need a power adapter in conjunction with the USB device?
