i had to buy a 300gb hard after the last one took a dump and i paid to have it installed and set-up so it'd be flawless. now i came across another problem; after trying to download a LEGAL torrent file (which i will never do again) i lost 2/3 of my hard drive. i used many of the free apps available to locate any unusual large files and came up with nothing except a 2.4gm private file. after using disk utility it says this: 297.8gb capacity 36.1gb available 75.4 gb used wtf? how the hell do i not have the 200gb i am supposed to have? help would be great so i don't have to pay again to have my mac serviced.
