Newb question.. I want to wipe my SSD clean of all the junk that has accumulated in it since I installed it, except there are a couple files and programs on there I want to keep, like Windows 7 and skype and other things like that. How do I wipe the SSD without screwing up my OS, or is there a way to do it where I can back my OS up and then wipe the SSD, and proceed to restore my OS?
