Western Digital Caviar Green 2TB WD20EADS Hard Disk Drive
On the back of the HDD, we can find the PCB, and the contacts that power the internal HDD motor. The PCB does not have any exposed electrical components, which is good, because this way there are less failures associated with touching the electrical components of the drive.
