So, my old HD SMART status is reporting that its failing, and the odd thing is it's been a month and the hard disk is still working fine. But for safety i bought a new Maxtor 329GB hard disk. So i take out the old HD and put in the new one and insert the Leopard install CD. But after the language choosing menu it says Mac os x cannot be installed on this hard disk. So i went to Disk Utility and Partitioned it to Mac OS Extended (Journaled) and retried. But it still doesn't work. What should I do?
