Hi My Powerbook is intermittently reporting SMART problems with its disk. Its covered by 3 year Applecare BUT I need more space anyway so was thinking of replacing drive with a 160Gb version myself. I have upgraded disk in almost every Powerbook I have owned including 3 TiBooks HOWEVER I cannot find instructions for the Aluminium version. Does anyone have them or is it so difficult I should take it to a shop? Cheers. Robin
