PC Hard Drives Exposed: A Pratical Guide To Hard Drive Repairs By Tyrone Wynn Kindle Edition PC Hard Drives Exposed: A Pratical Guide To Hard Drive Repairs Course Overview The course is designed as an introduction to the design, function and components of the electronic and electrical circuitry of Hard Disk Drives as incorporated into the drives’ Printed Circuit Board (PCB), together with the possibilities and techniques for the recovery of data where such components have failed. It provides an overview of: The physical components of PCB’s: The Interface – The connection to the host computer that provides the channel for communication with the host, data flow in and out of the drive and also provides the power the device needs to operate The voltage protection and filtering circuitry that control the voltages supplied to the drive The Central Processing Unit (CPU) – The main processing chip of the device that controls all drive functions Motor Controllers – These chips control the operation of the motors that spin the drive disk platters and move the Read/Write Head Assembly to track the data stored ROM and NVRAM Components – Onboard memory storage devices that can hold key information and firmware needed for the correct operation of the drive Device failure scenarios: Interface failure Other component failure and PCB damage Motor Controller failure ROM and NVRAM content corruption Data Recovery Techniques: Diagnostic procedures Component replacement PCB replacement Equipment and/or facilities required Spares requirement, matching criteria acquisition Onboard firmware reinstatement
