Hi again - thanks everyone for your help so far. I still can't get it to do anything. I've tried 5 different CD's (all mode2/ form1), all burnt as slow as I can (I choose 1 speed in IMGburn but the drive ends up burning at 4X) with newer versions and older versions but no luck. Also, the last CD (the latest V32 with mods) didn't eject. I had problems ejecting before but normally the hold the button for 3 - 6 mins and then press it again works. But not any more so I had to take it apart to get the CD out. I've put it back together but it still won't read any CD's. It was fine before I bodged the OS upgrade so I'm assuming the laser etc is good and it does make the noise like its trying to read the CD. I've pretty much accepted that I'm not going to be able to fix it. :-( Anyone on this forum in the UK know somewhere I can send it for repair (who know's what their doing, unlike me!). Thanks
