I'm assuming this is a firmware/software related issue. But during playing a game, lets say Ratchet and Clank, the game from time-to-time tell me the memory stick has been ejected, and then tells me its inserted again. Im not ejecting it manually, nor am I violently shaking the system about. Its not keeping me from playing a game (mostly), but I'm constantly forced to re-save which breaks up gameplay. Any suggestions?
