I've accepted I will have to buy a new hard drive after getting Error Code 68 and nothing suggested to do has worked, but it seems mindblowingly defeating to have to restart literally 6 years of saved data. I need to transfer data off of my current hard drive into a new one. Also, is there any way I can retrive my gamertag from a new hard drive if data transfer is impossible? I have craploads of microsoft points and a continuing monthly subscription to xbox live. I really don't want to lose my achievements either. PLEASE HELP!
