Are you sure that is JUST a CD drive (not DVD)? That does make a difference, and yes it may be incompatible with Windows 8 (especially if it is just a CD drive). Look up the model on Acer of the Drive and see if it is Win8 Compatible or not. If it is that old (CD) they may not support it, hence Windows 8 is looking at you like "what is that?" and that may be the problem.
