I had got a Samsung DVD RW for my computer which running on Windows XP. When I connected the DVD RW it does not comes in My Computer. The drive is not reflecting in My Computer. But when I press the button on the device the tray comes out. The light is blinking on the device. Does it is not detected by Windows or it is the issue with the firmware. Also how set up a jumper settings by which I can set up it as a Primary Master. Thanks in advance.
