my friend has an ibook and when he starts up the comp, the infamous flashing question mark comes up. he also gets an error msg saying something about his startup disk memory is running low. from wut i've researched, it seems his hd is failing. i feel obligated to help him cuz i bought him the ibook thru ebay. can someone tell me whats wrong?? if it is a hd problem and i hafta install a new one, anyone know where i can get it installed cheaper than going to the apple store or a comp tech shop?? i know its a very delicate process and i dont wanna take my chances with it myself. if theres anybody out there from buffalo, ny that is handy with macs, please let me know asap!!
