Hello!
I wanted to format my Mac's hard drive but couldn't because the disk utility didn't allow me. The erase and all was gray and uneditable. What I know is that I can't format the same drive I'm using or something, right? I tried to launch the OS X Lion app but it didn't work.

How can I make this happen?
