To transfer firmware from your old PCB to a new one, you will need to perform a firmware transfer process. This process involves removing the firmware (BIOS) chip from the old PCB and soldering it onto the new PCB. The firmware transfer process requires specialized tools and expertise, and it should only be performed by a professional data recovery technician or someone with experience in PCB repair. It is important to note that firmware transfer can be a delicate and complex process, and if not done correctly, it can cause further damage to the hard drive.
