Nec Nd-6500a

I just bought 25 box of Maxell 52x CD-R’s, but they won’t burn at all with my LG GSA-4082B. I have the newest firmware (A209?) and I don’t know what to do anymore. So I thought I would sell them to my friend. He has NED ND-6500A and I am not sure will they work with his burner. Could you tell me the thruth?
