Replace the drive #1 Maxtor is not the best drive out there. #2 its probally a 40 or a 60 you would probally be better off with a new 120 or something like that

i have owned macs for a long time now i actually work for a company fixing them and my rule is if it does pass S.M.A.R.T in any way shape or form replace the drive and then i put the drive in a external firewire enclosure and zero it out and then see if that fixes it and gets it out of red if not i throw it away. thants ur best bet
