I have this HP 8200i or 8100i I forget which one but anyways here's my problem. When I put a cd in (blank or a store boughten) sometimes the burner will not read from it and the light keeps blinking.. if I reboot my machine and keep the cd in then it will read it fine. As soon as I open the try and put another cd in then it does the same thing. It won't read or recognize the cd until I reboot with the cd in the drive. I am running Windows XP Pro but this has happened on any OS I run. any suggestions?
