Whenever I try to make room for windows in bootcamp, partition the drive, I get an error saying "harddrive cannot partition because some files can't be moved, reformat the drive" something like that I googled a bit and found out that I needed to defrag my mac, or so I thought. So I bought iDefrag and ran quick (on-line) defrag (only option available to use, took over 2 hours) Anyways, after I defraged I went to bootcamp to try the same thing, guess what? It still gives me the same error! Holy ****, I bought idefrag for nothing!! Can anyone help? What is this BS?
