Well we got our hard drive today and got too excited in installing it in the ps3 to replace the 60gb drive. Can you see what happened?
Well we got it out with vice grips and now we're only using 3 screws. We plan on sending the stripped screw to Sony to request 4 replacement screws. We thought it was over.
