I want to get rid of my 360 and sell it off for parts. I want to keep my hard drive so I can transfer the files onto another hard drive when I buy a new 360.

The question is, by keeping the hard drive, am I taking all my personal information with me or is there an internal drive in there that I should be worried about? If so, how do I go about clearning that up? My 360 is dead so I can't boot it up and go to any menus of any kind.
