i have a ps3 60gb fat version. the blu ray drive is out. it will not read games, and upon fixing it i broke it even worse. i have found several blue ray drives for sale, but for the 40gb, and the 80gb fat models. not the 60. so my question is are the drives out of the 40 and 80 compatible? and if not, how can i find out what type of drive my ps3 will take?
