I just bought a 200GB HDD, which i thought was a Maxtor HD Model 6B200P0, but the device ID in my Device Manager is WDC WD2000BB-22GUA0. I just "installed" it, but it doesn't show up in My Computer nor am I able to save things to it. The Device Manager says it's working properly. How the hell do i get it to show up in My Computer, and to save to it??
