What is Hard Drive PCB?
The green board on the bottom of the hard drive is known as Printed Circuit Board(PCB). The main function of the PCB is to supply power to the hard drive, maintain speed and rotation of the spindle, and control all internal operations through its firmware. Essentially, PCB is the brains of the hard drive that all components are heavily dependent upon.
