My dad's old windows 8.1 computer has an ASUS DVD RAM GH95N optical drive that used to recognize discs but doesn't anymore. The drive appears in file explorer but when you put a disc in, it never gets recognized. From what I read online it sounds like a windows update broke the drive. He does not have a system repair/reinstallation disc. ASUS doesn't list the drive in their support section, so there isn't a reputable online driver available. The guy who wrote this question describes exactly the problem I'm having, but doesn't seem to have gotten a solution. Anybody know of anything else I can try, or is my dad SOL?
