I have a Dell laptop with a Matshita UJ-875S ATA device. When I insert a DVD it makes a terrible clunking noise and won't play. It will eject the disc after a while. Do I need to replace the drive and if so, does anyone know how I go about finding one? I tried looking on ebay and with various manufacturers, but no luck. Is there a comparable product made by a different manufacturer? Any advice would be appreciated.
