I have a good old NEC 3500 that has been working flawlessly for as long as I’ve owned it. But all of a sudden it can’t read DVD’s at more than about 13.5x max. It’s attached to an external USB case. I suspect that something in my system is causing the problem, but what can it be? I attached a screenshot of CD-Speed. All my DVD’s show the exact same graph.
Any input is greatly appreciated.
