Sorry I'm posting this again, I think this thread needs to be in OSX rather than in MBP: WOOWWW!!!!! I really don't know what to do now! My external HD disappeared after I installed lion recovery disk assistant to it with all my information on it! I just can't believe this recovery erased everything I had on my HD!!!! I know I'm freaking out, but this was my backup external HD close to 1TB personal info on it, I stored all my files there to keep my MBP hd clean!!!!! HOW CAN I UNDO IT? I hope there is a way!!!!
