my warranty finished d, called wd support to try my luck, they say need to send in for RMA and the files inside need data recovery, ridiculous

Google a lot and apparently the control board is the culprit, the hdd is still ok 1, i pry open the casing and found the control board part number 4061-705094-001 Rev 13R

the data in the hdd is encrypted by the controller board, thus putting the hdd into a generic casing to access the data wouldn't work

the solution is to replace the controller board, found a seller online but just buying the controller board would cost over 200 whereas a new 2tb drive is just 350++ 
anyone here experience the same problem and manage to fix it? or if you know where to get the controller board locally?

any help is very much appreciated, thanks.

My 2TB WD My Book Essential 3.5" external drive, model no. WDBACW0020HBK-01 suddenly failed to power up, it just sit at a corner and i rarely move it

i check the adapter and usb cable, both working fine

the power input socket on the external drive is kinda different, i tried to plug in the unifi modem power adapter but can't fit. But the external drive's power adapter plugs in nicely on the unifi modem and powers it up nicely

i barely move the usb cable because it's always plugged in, so i doubt it's the problem

regarding the encryption, i've checked online and rule of thumb is must use the exact same part number and revision of external hdd pcb (controller board)

i'm not that technical =/ will drop by lyp later to check if the adapter is working as it is supposed to

the part i'm looking for is the external hdd pcb (controller board), not the pcb that is attached the hdd, the external hdd pcb (controller board) will be attached to the hdd through the sata ports, and the external hdd is connected to the pc through the usb 3.0 port on the external hdd pcb (controller board), power is connected through the power input port on the external hdd pcb (controller board) as well

initially i thought could have just take out the hdd inside and put in a generic external casing, as i dig deeper, found that the external hdd pcb (controller board) hardware encrypts the data into the hdd inside, must go through that external hdd pcb (controller board) to access the files inside 

as can see from the youtube vid, the guy change the controller board of the external hdd, and that's the part i'm looking for

Do Not: Under no circumstances should you attempt to swap the controller board on one of these faulty drives with one from a working drive. This is because the information held on the failed drive is unique to each drive. Changing the controller board may very well cause a mechanical failure and render your recoverable data unrecoverable.
