My GH-20NS10 just “spat the dummy” with lots of rattling when starting a burn. Couldn’t open it by any method! Couldn’t even open the draw with a paperclip. It just released the blank DVD inside to add to the rattling.
Something obviuosly broken and it has only burned 5-7 DVD and read about 20 in it’s 5 weeks of life. Let’s hope it’s just an odd failure?
