If you want to keep track of your HDD (good idea, IMHO), you need to enable SMART on it. Don't know why OFF is the default, but it is. You can do a quick search for "Hiren's boot CD" (look for a Thai server, much faster.) There's a utility in the hard drive section that does that, and a lot of other good stuff - I'd recommend having it on hand for the future, too.
