Hard Drives Are Magic

How A Computer Hard Drive Works?: I can’t believe hard drives actually work, and this cutaway video of one in action just makes it even less believable for me. The speed that arm moves at the end of the video — there’s no way it’s actually doing anything at that speed. This is all just a trick.

On the way back from a conference once, I sat next to a guy who developed firmware for Maxtor. He explained to me how it all worked. I thought he was full of crap then, and I still do.

It’s all just magic. There’s actually a little leprechaun down there reading stuff off a scroll.
