DVD/CD rom erased!

I've made a dual boot system but in the process my D: dirve which used to be my DVD/CD drive seems to be overwritten. I noticed that from your screen shoots you seem to have the same set up. When I boot in vista the E: drive is partitioned for XP but my D: drive is still not visibale. If I boot to XP the D: drive is associated with my XP os system so there is no dvd/cd drive visable there either. I would try to change the path of my dvd/cd drive in the Vista disk manger but as I said vista is not displaying that as a drive anymore. Do you have a fix for this problem?
