How can I tell if my laser is dead? This drive was working yesterday (read and could burn). Today it can't read a disk. I tried a game and a music CD. Symptom is drawer closes, green led blinks, I can hear the disk spinning, but then nothing happens. I use XP and the Explorer shows the optical drive but no files on it. Device Manager says optical drive is working fine. Troubleshooting wizard is no help. Lastly, I uninstalled the driver and installed the default one from XP. Still the same problem.
Any suggestions? I'm thinking it might be the laser but am not sure how to verify if its working properly, or is dirty, or if it could be something else entirely.
