I have the same clicking noises problem. Also waiting to receive a box from Sony. Temporary solution (though risk losing data and corrupting the drive): Get the BLOD, once you hear the clicking noises, unplug the power for 10 seconds, plug it back in. Boot into the "safe mode" hard drive scan. System turns on. If you turn it off for more than an hour though, same BLOD & clicking noises though. At least you can play SOMETHING on the fancy black brick before you send it in.
