Hello! I have a Lenovo T40 laptop with a DVD/CD drive (D). Lately, it does not seem to want to do anything. I can't get it to open when I push the button or do the Eject from within My Computer. If I load a data Disk, it does not bother to read it and if I load a music CD it does not know it exists. Occasionally it will work for me but I am wondering if it is being blocked off by some program that is running. Any thoughts on how to test if the hardware is working?
