Ok. I have chatted several times with HP thinking that it might be a problem with my PC. My problem started this morning when the power strip was kicked off. I started up again and now my MadDog external USB DVD burner is not detected in My Computer as a DVD drive. It is detected, but (in Device Manager) under disk drives as USB 2.0 Storage Device and also under USB Controller as USB Mass Storage Device. I have tried to update the drivers, but will no success. I uninstalled all USB devices, restarted and let the them re-install. Still same problem. When I turn power on/off or plug/unplug I get that beep when new devices are connect.
Everything was fine last night as I burned a few DVD’s. I have also tried switching to different USB ports, but still the same issues.
