haven't had case open just restored my reg to the 28th & still no d&e drives dvd will eject cdrw wont because it was containing rewritable with direct cd turned off,secondary ide not even mentioned in system config anywhere

Have you installed any other hardware lately? You may have bumpped the connections from the cd ribbon cable. If you haven't , you could try removing the problem device from the system devices list and Windows should locate and reinstall the drivers during bootup.
(*Usually, some configurations will differ, The secondary IDE is on the motherboard and has the ribbon cable for your cd and rewrite drive attached to it. The primary IDE has the ribbon cable to your harddrive attached to it.)
