The problem is that I've done that and the internal hard drive does not show... it's literally not visible. I am running the latest Mountain Lion OS X update as well. I can\t recover the hard drive. In DU it shows to left as "disk 1". I can't use the external HD as as a source and the "disk 1" as the destination to erase and rewrite. It says that I don't have enough memory lol.... I'm just ready to buy a different HD to replace it with and reload from the external HD. But then I am wondering how to wipe the old external hard drive clean since it won't be in the laptop.
