This question is about the relationship between information, entropy and heat. I think it was in the 1970's the Hawking claimed "information is lost in black hole evaporation". This did not mean it was just inaccessible, but that it has literally disappeared, gone forever. In the Black Hole War, Leonard Susskind 2008, pg 23 discusses when he first realized this must be wrong: So assuming there IS information sitting in a black hole why is heated generated when it evaporates? Is the existing heat with the black hole "released" beyond the event horizon and exposed so we can observe its effects...is that what Susskind is getting at?? And if so was all the "hidden stuff" necessarily so hot before it became a black hole..doesn't seem so.
