Hi Machead, (seems strange referring to you by this name!), the drive is only a CD/ DVD ROM (will not burn things only read them) so I was assuming that`s why it`s not listed under Disc Burning in System Profiler? It`s also making a short spinning noise (though it won`t eject & I`ve tried pretty well all the alternatives spoken of in Google) when the track pad etc. is held on re-start so I`ve also been assuming the ribbons are connected. I`ve been advised on the Mac discussion forum that my torx screw driver may be able to undo the difficult screw on the lid of the optical drive whereas the small Phillips head screw driver I used for the other screws may be found wanting..?
