Thats kind of a strange problem. I'm almost thinking that it might be a hardware issue (defective drive) but thier are a few things that I would check out first. Try reinstalling nero and or try another burning program (just find something with a free trial for testing purposes). Try uninstalling it in device manager and let it redetect and reinstall it. Double check your jumper settings on it and on the other drive if thier is one on the same channel. If all that fails, try a diffrent ide cable.
Did you get this drive new or used? Also, I'm not very farmiliar with laptops(that is a laptop burner, isn't it), but it should be about the same. Did you use a pre exsisting ide cable or a new one?
