specifically drives D and E are, they can be hard drives, partitions of hard drives, CD drives et al. Seems that you mean the two optical drives.
Who installed them, or is it it, How are they jumpered?
What ports are they/it on. Did you install Nero or other CD writer software at the same time. With XP there can be conflicts with Roxio, because MS usaes a version of Roxio. Here's one link with a possible solution.
