Lost Data on Macbook Pro After I could not boot my Macbook Pro (OS X Lion 10.7.5) I tried to run safe boot. I thought it worked, but only thing it did was booting the mac without any data i used to have. All the software is there. It's like a brand new mac with full applications. My storage seems as full as before so I know the data is somewhere inside my Macbook. How can I find them? (I'm still logged in as I always were and there seems to be no other accounts)

P.S: I know the ways that requires payment, but I (with my ignorant logic) conclude that since my storage is still seems full with everything I have I may not need it. 

Edit: ALSO i downloaded data rescue demo to scan. But for some reason my HD can't be scanned. When I tried Disk Warrior it says "Directory cannot be rebuild because this is the startup disk"
search your computer with Grand Prespective and it will show you your entire mac, and what and where the data is
