This is regarding the NEC DVD-+RW 6500A optical drive in my laptop. According to the model number it is supposed to be able to burn DVD but it cannot. So I thought maybe I have an older version driver on it. I went to Dell Support to look for the latest. I can't find a driver instead I found a firmware. So I downloaded the firmware appropriate for it and as soon as I installed it I was able to burn DVD on my laptop.
I just thought I have to share this.
