I'm going to go ahead and guess that the computer component you take most for granted is your HDD. No longer! Bill the Engineer Guy—our favorite uncreepy uncle geek since Bill Nye—unfolds its many mysteries. [TDW Geek]
This video sends me a strong message in favor of Digital Hard Drives. As impressive as the technology of an analog hard drive is, and it is amazing, I shudder to think how the digital wonder that is a computer depends on such a complex mechanical device. A big magnet is the engine! I had an expensive watch ruined by the HD in my laptop. Couldn't figure out what happened until a metal pen was sucked against my laptop from about 4 inches away. Really powerful magnet! I'd love to see a video by the same guy about SDD engineering.
