I recently brought a NEC 3520A and am having a real problem getting it to work. It is installed on my computer as a Slave to my Lite-On CD Writer which come with the computer. Windows XP found the hardware OK and installed it using standard drivers (I didn’t get any drivers with it). I was running DVD Shrink to back-up my DVD and put a blank Maxell RW DVD in the 3520A with the master DVD in my CD Writer/DVD Rom. DVD shrink didn’t seem to recognise that I had a blank disc in my 3520A and in windows explorer the drive name for the 3520A kept changing from DVD RW to CD Drive. I only have limited knowledge of computers so can someone help me and explain what the problem might be and step by step how to fix it.
