“Ka-chunk... ka-chunk... ka-chunk... tick... tick... tick... Ka-chunk... ka-chunk...” That's just not a sound you ever want to hear coming from a hard drive. It's the sound of a hard drive trying to move it's read/write heads into a position that they don't seem to want to go to or its trying to read a sector that just isn't there anymore. Of course, modern hard drives have come a long way and are amazingly reliable, but if you work with computers long enough, you're bound to have one fail on you.
