Often computer repairing and maintenance engineers may face the problem that, when they connect the damaged hard disk to the computer, the computer does not start. If the damaged hard disk is connected to an already on the computer, the working computer also stops and shuts off instantly. The reason behind this issue is the shorting of PCB inside the Hard Disk. If you might have heard any clicking noise inside your hard disk, then you might either be facing a damaged head issue or there could be damage in the PCB of the hard disk. In this session of Electronic Data Recovery Training, we would be discussing about various reasons behind PCB damage, the symptoms of damaged PCB, and will learn to repair the damaged PCB step-by-step. We will also study about PCB models of different hard disks, and will also discuss their general faults.
