Completely different drive in my slim. 3 ribbon cables on the back that pull straight up out of their connectors. And one wide ribbon hidden underneath and almost impossible to get to. After disconnecting the 3 visible cables lift the back of the drive about 3/4" and use a plastic spudger to release the clip on the cable before lifting off the drive. Reinstalling is a nightmare. The cable has a black line to indicate how far to insert into the connector. Get it in there somehow then use the spudger to push the clip down. If it's not level release it and try again and again and again until you get it right. Sony must use some awfully small fingers when they build these ;-)
