Samsung Write Master SE-S204 drive problems
Unfortunately there are many potential causes of the problem you describe. What OS are you using? Try the LDU (Lightscribe Diagnostic Utility) that is available on the download section of the Lightscribe website. Be sure the USB connection is NOT a hub connection. What other devices are you running on USB bus? Verify the PC bus is not USB 3.0...USB 2.0 seems to cause fewer communication problems...
