Hello, If anyone has come across this predicament and survived!
Just replaced my Hard drive yesterday for a larger size. I had copied my latest saves from my current game I've been playing to a USB stick. I followed the instructions online and they were very straight forward and My PS3 is working just fine. It's just when I go to play my game, It tells me I CAN NOT add anything or Save data to this because it belongs to a different user.
I have logged back into my ps3 online account and I used the same name I has on my last hard drive when it asked me to make a name for myself after the reboot .
Let me know if there is any ray of hope for my problems, I really don't want to start another Skyrim game.
