Western Digital Controller Board burnt

June 3rd, 2015

Question:
I have a Western Digital 1TB hard disk -32MB cache, details are:

Model: WD10EADS-11M2B2
Date: April 2010
Control Board Number: 2060-701640-007 REV A

I am referring to the number that is etched on the board and not the one printed on the paper sticker on the board.

Problem:
The drive is currently not usable because a chip in Controller Board (SMOOTH Motor controller) is burnt and the drive is inaccessible and I want the data in it.

Answer:

You can swap PCB to try. Please refer: http://www.hddzone.com/wd-2060701640007-pcb-p-281.html. You need to change the BIOS chip before swapping PCB.

We know PCB includes 2 parts: Hardware (components) and Firmware (data in the chip); The firmware includes HDD’s unique configuration data. The HDD needs this unique configuration data to work. In order to have same circuit board firmware, we have to transfer the unique configuration data from the bad board to the good donor board.
