I have a PS 500 gb Super slim, ran the new update and luckily had none of the problems a lot on the board are. However on games like Skyrim, I get corrupted data. I deleted the game and dlcs, reinstalled and still the same error so has to be related to the firmware upgrade since never happened before.
Any options rather than a reformat. Using a very slow ISP and would take forever to redownload everything.
