My and my cousin where using out computers, (mine is a PB and his is a MB) when both of the lost all of their information at the same time. The files are still there, but there's nothing in them. it still says that I only have 20 gb free on my computer, so that means it still thinks it has the information. I'm not sure what could have gone wrong, my cousin was setting up a brand new MBP so I don't know if that could have messed with it in anyway. Is there a way to get all my files back or anything? Preferably free, thanks alot.
