OK I read almost every post on the subject but couldnt get anything to work. I have a Toshiba satellite Laptop which doesnt recognize my cd drive anymore. I have tried both the CDgone registry key and removing the filters with no success. Actually, when I removed the filters I was able to see the cd drive, but with a question mark next to it. Then when applied the cdgone key, disappeared again. The cd drive doesnt even show up in the device manager. Is there anything I can do? Thanks a lot!
