Now my 2008 MBP warranty is going to expire in around a month. I still have the same HD and it really hasn't had any issues. However every month or so I do a test with a program called "Smart Utility" and today it gave me a "Pending Bad Sector: 1" failure. Now I know what that means, but will a Genius go by that, or disk utilities smart status? Also, since I am there, should I get my board (with the 8600) replaced, or should I wait till it starts having issues? I know I have some time (4 years from purchase date), but I just worry since I have heard horror stories of someone MBP board not getting replaced cause it can't boot.
