half of my stuff has disappeared,

somehow half of the stuff in my c drive has disappeared. stuff like my Music, Videos, Pictures and Programs. I had over 150gb of stuff in my folder and now theres only 10gb. Noone has deleted it or anything, also when i check the space on the c drive theres 80gb usage so it cant of been moved anywhere else. anyone know what could be wrong?

Did you have any niggers come near your computer lately? The niggerfield is known to mess up harddrives.
