I feel a little stupid asking this question, but I just found out that my roommate has been using my brand new imac for viewing porn. I know its just porn, but Im really pissed about it. Anyway, I don't want any record of his porn endeavors lurking around on my HD. I know its not doing any harm, but its the principle of it I suppose. So if I boot up from the osx disk, erase the HD, and then restore from time capsule, will this eliminate whatever he has been looking at, or will the time capsule just put it right back on there. Thanks.
