Beneath the Board

Underneath the board area unit the connections for the motor that spins the platters, also as a highly-filtered vent hole that lets internal and external air pressures equalize:

Removing the cover from the drive reveals an extremely easy however very precise interior:

The platters - These generally spin at 3,600 or 7,200 rpm once the drive is operating. These platters area unit manufactured to wonderful tolerances and area unit mirror-smooth (as you'll be able to see during this fascinating self-portrait of the author... no easy thanks to avoid that!).

The arm - this is still the read/write heads and is controlled by the mechanism within the upper-left corner. The arm is ready to maneuver the heads from the hub to the sting of the drive. The arm and its movement mechanism are extraordinarily light and quick. The arm on a typical hard-disk drive will move from hub to edge and back up to 50 times per second -- it's an incredible factor to watch!
