Hello, I wonder if you can help me out.. My drive is not recognising any blank cd/dvd when i put in computer. Even a real cd or dvd is not getting any response either! It has only started happening today! It's like the computer doesn't recognise it. The computer just spits it out after a couple of seconds. I've restarted and shut down but nothing seems to work. Any ideas? I'm using Mac OS X Version 10.4.11 I've also reset the PRAM and nothing has changed. I can't copy cd'S, dvd's, can't play cd's or dvd's because the computer doesn't seem to register them! I've also clicked on "About This Mac" but the "More Info" button is shaded and won't let me click on it! I'm a novice so any brilliant, amazing, simple advice would be greatly appreciated!
