I’m having similar problems with my dvd rw drive not working properly. I recently used it to install UT3, like… 2 weeks ago recent, and suddenly it stopped working. It worked through the installation and for some time after, but now it has ceased to do anything. Under the device manager it shows the drive, but it will not update drivers when I search for them. I found out Sony has a KY06 firmware update on their site, but when I click the .exe to run it, it says “This utility is only for the Sony DRU-800A drives” and then a little further down "Detected drives: ". Sorry if I tend to repeat myself, but any help would be much appreciated.
