I have a Dell Precision M60.  I was using the NEC DVD+RW ND-5100A but that drive went bad and wouldn't read so Dell replaced with the HL-DTST DVD+RW GCA-4040N (which I think is a Hitachi product).  I can't find any drivers or firmware on this product on dells web page.  This drive will copy a DVD+R but you can read on the computer or a DVD player.  Does anyone know where to find the drivers or firmware for this product.  Is anyone having the same problem?
