I have a Dell XPS that had an internal cd burner in it that stopped working. I purchased a new internal cd burner from Dell but it to had the same problem. The way I always copied files to a cd was just by copying and pating it to the cd drive in windows explorer and letting windows XP do the rest. To get it to work I had to install a third party cd burning software (roxio) and that is working. Any ideas as to why I just cannot copy and paste anymore straight through windows xp? When I try I get a windows error saying that the disk may no longer be useable.
