I saw the thread about Changing back to the OFW from the CFW. And one person told him to reformat this PS3 hard drive. I have OFW 3.60. i read about the CFW for a while but I became interested in doing installing it. I have been waiting for a 3.60 compatible CFW to come out but I have a question. Is the system software installed on the Hard Drive or on the PS3?
