So just recently my macbook pro started acting up and slowing down and i've been seeing the spiral of death a lot and whenever opening i tunes i get "an unknown error occurred (13014) i have looked into this previously but then i found out the problem is with my hard drive. I cant even format my hard drive or repair it. I have lost my printer driver and i cant seem to download anything new to my mac. What can i do?? PLEASE help!! its driving me nuts and i'm thinking about just buying a new hard drive. Any suggestions?? Thanks guys!!
