A lubricant coating shields the disk from damage during contact with the head, which can fly back and forth across the disk dozens of times per second.

The sound the head makes when it digs into the surface of the disk rendering the disk immobile is similar to the sound made when the brake shoe on a Chevy makes when it finally runs out of brake lining and it is metal to metal contact just before the brake welds the wheel in place.

Ouch! I've had a hard disk "go bad," but I don't think that's ever happened to me before . . . Thankfully! I guess that's the reason you should never move your computer while it's running.
