This weekend I installed a 250GB hard drive into my PS3, turned it on, formatted it and off I was running. The system recognized the drive fine and after format total space came to 132GB. But you all the know the story about GB ratings and true capacity. Just thought I would inform the community of the mod and the highest HD mod I've seen so far. If you have any other mods for the PS3 (originally 20GB) reply or PM me.
