Swapping my PCB & firmware Chip

WD Internal Drives Desktop & Mobile Drives

I have a 1TB WD My Book. Someone in my family stupidly plugged in the wrong cord and killed the PCB board.

The family member didn’t want me to know so took it to some local computer tinkerer who basically just tore some pieces of the old PCB off. So the old is completely useless. I am hoping one of these things was not the firmware chip that I need :frowning:

This is not life of death data retrial but I would like to save the files if I can and hopefully make my drive useable again. 

This is the murdered old pcb:

I purchased a new PCB which had the same numbers on multiple sections ( 2060-701537-004 rev A ) and ( 2061-701537-q00 AD )

When I plug it in I cean hear it spinning up it’ll click multiple times and then stop making noise. I then hear the sound from my computer indicating something has been connected. It does not show up in my computer. It does show up in Devices and Printers & Disk Management ( where it says Disk 1, not initialize with no option to initalize though it shows up sometimes but when I click on it I get an error. ) So I assume the PCB is functioning but needs more data to  fully work. 

Can someone look at my murdered board and tell me if I still have the piece I need for the firmware before I send it off to get the chip transfer ? 

Nevermind. I realised that mine was of the large chip variety which was torn off. :(

You can try contacting one of the companies on the list bellow for data recovery.

This PCB’s BIOS is integrated on the Main Controller IC. You should exchange the Main Controller IC to let the HDD be recognized. Move the Main Controller IC(the biggest chip on the board) is a complex job which need you have certain techique. Some electronics repair shop can do it.

Data recovery professionals will rarely need to transfer an MCU from one PCB to another. The subject drive appears to be a “ROYL” model. These drives often store backup copies of the flash memory in a hidden System Area (SA) on the platters. The professionals simply install the replacement board and then access the SA using their diagnostic software. The “ROM” is then rebuilt and reprogrammed with a single click of the mouse. For this “data recovery” service, the user will be charged anything up to US$2000.

The following article shows how this is done using SalvationData’s HD Doctor.
