I had my 1.5 year old MBP in for repairs yesterday and as part of their "normal diagnostics" they told me that they found that my hard drive has a number of "bad sectors" and that it is at risk of failing completely. (The issue it was in for had nothing to do with the hard drive). They told me that the hard drive is nearly full so this means the bit that is gets used more and then can begin to fail like this (this was their lay description for me). I have now Googled this, and it seems like what they have told me is legitimate, but I just wanted to confirm with you guys. Does what they have told me seem plausible? I have backed everything up, but just wanted to double check before I get a whole new hard drive put in. (Obviously it can seem a bit suspicious when it goes in for one thing and then something else is "wrong.") Thanks!
