You did say that the cd writer worked OK when on its own cable, right? That means there is no problem with the cd writer, but with the way it is connected. However, WHERE you put the IDE cable to connect the cd writer may also be important.
I'm afraid that investigating this takes a few combinations of the relevant hardware pieces, so maybe that's what you have to do to make sure :)
