Had a problem with my optical drives, both CD and DVD drives, suddenly disapearing from "My Computer" (in WXP SP2). The device manager shows yellow exclamation points beside each drive, noting error code 39: Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. Nothing I did would get the drives back. So I googled the problem and discovered many who were experiencing the same problem. They reported a solution by editing the registry, to remove UPPER & LOWER FILTERS. See here. ••• continued ••• Worked like magic, even tho the problem description did not specifically apply to my system. (I didn't remove Easy CD Creator.) Not sure what caused the problem. I suspect it began after a Windows update session, cuz that's the only thing I recall changing. Not sure, tho. Appears third-party software (e.g. burning programs) install these filters. So you might have to re-install your burning programs afterwards. For more info, here is a Google search pre-configured for the query terms: cd dvd error code 39 device manager yellow windows xp |
