So I put in my 8GB USB Drive (Thumbstick) and it erased everything on it and changed the name to "Recovery Disk." It put Recovery Disk Assistant on it. If I ever need to re-install Lion on my iMac or Air I just put in the USB and upload it to the system from there? It only takes up 1.7MB...this seems kinda small to have Lion on it? PS - Can I change the name of "Recovery Disk?" If I want to add other stuff to my USB again can I also do that too? Or should I just leave Lion on it? Edit - Can someone please explain an EASY way to add Lion to a USB AND still allow me to add files to my USB?
