I have a Toshiba A135 running Vista. I was getting this message in the Device Manager on my DVD/CD ROM drive. I followed the instructions in this thread: I uninstalled my CD Creater software, then I deleted the entries in the Registry. I rebooted. I checked the Device Manager and the error was cleared and it said it was working properly. I reinstalled the CD Creater software and I am good to go.

Thank you, this site really helped me.
