Okay, It's stupid question day... I'm going to upgrade my primary hard drive, then erase the old one and use it for data. I figure I'll give Carbon Copy Cloner a try. After I copy stuff over, how do I specify that I want to boot from the new one? How will I even know which one it is? Won't they both have the same "Macintosh HD" name? Any tips for making the old one "unbootable"? I'm a little nervous about this. Thanks.
