My dad has killed 2 burners so far, 2 different manufacturers, different models, different speeds, but they both died because of a laser alignment thingy (so he says). While we are getting a new one (it was still under warrentee) I would like to know how to stop this from happening again. Both my parents smoke, but I don't THINK that's the problem because his regular CD-ROM Drive has lasted years, and the rest of his computer has lasted a few years (the burner is only 4-5 months old). Was it just bad luck? What caused it to die?
