I currently back up my MBP hard drive contents to an external hard drive via time machine. If I reformat (i have too much crap on it and its slowing the computer down), can I access the hard drive contents and "restore" just certain parts? I have never had to use time machine to restore anything, so I am a tad unfamiliar with the process. The main thing I would want restored are my itunes content, among other things. Thanks! Edit: Changed "hard reset" to "reformat".
