Ok, so this is my first time making a post here on Macrumors, with that formality out of the way, I'm having issues using Boot Camp. I get the most common error, "the disk cannot be partitioned because some files cannot be moved." I have attempted to use disk utility via the Mac OS X Install DVD, I have attempted iDefrag, and a couple of other things. To NO avail, I have not succeeded with anything. Is my best be to just "reformat" my computer? If this helps at all, it won't let me actually run a full defrag, it's only allowing me to do an on-line defrag.
