Hello everyone, welcome to data Empires. We already know that the firmware of the hard disk is just like an Operating System. The way in which the operating system checks itself at the time of system boot, and provides the GUI system environment for the user, similarly, the firmware also tests itself and gets the hard disk ready for the data operations.
The firmware of the hard disk is stored in two parts. The first part is stored in the ROM, or M C U I C on the PCB. The second part is stored in the service area on the platter. In this training session, we will discuss the WD firmware modules and module backup.
