OK, Yah i tried to do the system backup from my 20gb (now 500) to my new 160 gb. I backed it up, then took out the 500bg and put it in the new slim and the 160 in my old ps3. I did the restore and the message came up saying some information could not be restored, I looked and none of my game data or saves transferred over. I put a 300 in my old one because the 160 would not hold all of my data and everything transferred fine. Must be an issue going from a olf fat system to a slim. Going to try the data transfer, then the memory stick if that doesn't work.
