If you are concerned about your hard drives health or want to know whether or not your system is exposed to Internet evil doers, then you should become familiar with Steve Gibson's GRC.com. While the popular SpinRite software is a commercial product for hard drive maintenance, Gibson also offers a number of free tools including ShieldsUp! a fantastic online tool that will identify open ports on your system in order to inform you of your PC's potential vulnerabilities. Steve is also co-host of the popular Security Now podcast with Leo LaPorte, while this show can often get a bit technical the duo does a great job of dumbing it down for general consumption. Everyone who has a PC connected to the Internet should give this site a visit.
