I have a Mac Mini, with lion, about a month old. I downloaded the recovery assistant and followed the on screen instructions and it said it loaded a recovery disk on a 8 gig thumb drive. (probably two minutes and you could see it loading something) You can't see it on the thumb drive and it said you would not be abel to see it. Is this all you need if you have a HD crash of something bad happen? If I need something else please help me out because I am not real computer savy. THANKS A LOT!!!!
