My G4/400 has an internal optical CD,DVD-R drive (Hitachi DVD-ROM GD -3000) and I also have an external CD,DVD burner (Pioneer DVD-RW DWR-106D) which I believe is the same as an Apple Superdrive. DVDs which I burn will not, however, read in the internal drive, though the Tiger DVD gave no problem. From the Apple support area I glean that this may be a firmware issue though I can find no firmware update, nor can I find a firmware reference for the drive from System Profiler. The nearest I get is Revision 020S.
While this is not a problem, it is annoying.  Does anyone know of a fix?
