Hard drive "click of death" demonstrated on video

Have you ever had a hard drive start making that awful clicking sound which you later found out meant certain death? It's not a nice feeling. You know what I'm talking about... Especially if you've never invested in a backup solution. That realization that all of your valuable data might be gone - forever. In this excellent video, by the guys over at TechWareLabs we get a sneak peek into what actually causes the sound and what - if anything - can be done about it. Although it may not make you feel any better if this has happened to you, there's a certain morbid fascination in understanding exactly what caused so much pain and heartache.
