Tried fresh installs, she works fine for a few weeks then starts rapidly deteriorating until the spinning icon on a reboot doesn't stop spinning. Safe mode takes 1+ hours to boot. I've taken it in to the apple store and was told a new harddrive would run me $900! Do I have any more options? 2011 13" 80gb hdd (Samsung HS082HB). Serial # S1BPJ16Q183188 Should I sell for parts on ebay?
