Well, it screwed up my HD icon and there was no way to fix it and since I didn't have a copy of the icon I still can't restore it. So I just found a candybar drive icon to put over it. It also crashed Finder. I also noticed 2 different style of icons, one as a temperature bar and one as a gradient fill, so that's also inconsistent. I'm on 10.2.4 with all the upgrades.
