How to transfer ps3 data to another ps3 offline?

[roywang]

My brother and I both have PS3's and we play in different rooms, I continuely have to move it back and forth and its gets old. Is there a way to transfer the game save data to his offline. I tried using a usb, and putting it on the PS3. However, it says "invaild save data" "You cannot use this data becuase you are not the original owner" what do I do or can I do to use the save data on his PS3 offline?
