Ok, I have an unique problem (I think). I have a Sony Vaio RX580 and I have a DVD-RW drive (Pioneer) that came with it. The system will not recognize the drive. The name of the drive is DVD-RW, however the type is CD Drive. I can burn pictures and CDs to CD-RW discs, but when I put a DVD-RW in, the drive makes a terrible sound and the computer does not recognize it. I have tried to get help from Sony, but nothing. Can anyone help me?
