I recently had to reinstall windows vista basic via system recovery. When I reloaded it my DVDRAM drive was missing. I look in System Devices and My Dvd/Rom drive is not there. I can put a dvd (even the restore disk) in my drive and i hear it spinning but the rom doesn't read it. I tried deleting the Upper and Lower filters and that did not work. I can not find a drive anywhere on the net for this drive. Any ideas or suggestions? I need to get this fixed. I've completed virus scans and even tried Microsoft Fix It. Please Help.
