WD ROM AND MICROCODE

Hello everyone, welcome to data empires. Friends, we already know that the firmware of the hard disk is stored in two parts. The first part is stored on the PCB of the hard disk. The second part is stored on the platter. If the firmware stored on the PCB gets corrupt or damaged, then hard disk is not detected, Hard disk starts giving a clicking sound, or the rotation of the hard disk gets stopped.
Therefore, before performing firmware repair operation to recover the data from the hard disk, or to repair the hard disk, there is a need to take the backup of the ROM first. In this video training we will discuss how to backup rom and how to check microcode of WD hard disk with help of basic firmware tool.
