Laptop only recognizes external DVD burner has CD burner

howdy! I Have fujitsu n6120 lifebook, and had recently purchased a external DVDburner to make some backup. but it only recognizes the DVD burner has a CD burner, that is when ever I put a blank DVD of anysort in it just doesn’t recognize it. The restore disk the laptop come with seems to only want to erase everything. plllllllleeeeeeeeeeeease haaaaalp - :sad:

Try an ubuntu live cd and test if you could write a dvd using that.
