Western Digital PCB compatibility if different VCM contoller

[SOSdonnees]

Hi,

I'm planning a PCB swap for a WD Elements hard drive.
Although a new USB 3.0 board would do the job, I plan switching the circuit board to SATA, as a more durable solution after the drive was repaired.

I could find the compatible SATA board and the MCU controllers are same.

However the VCM (Voice Coil Motor) controllers are different (first 3 letters are same).
Is there some compatibility rule for this component?

patient's VCM: B20AA
donor's VCM: B20B8N4

(N.B. I'm aware about swapping the U12 chip.)

What is the PCB number?
Also this drive may be encrypted, do you need the data?

You can copy and paste, well done.

I can copy and paste beside I can distinguish between encrypted WD and not encrypted.

You are of course correct, I didn't notice that.

That's what I tried to say. No offence at all

To all others who may be confused by this exchange, Elements models are not encrypted.

Just swap. 99% i haven't bothered while changing/converting from usb 3 to sata boards...specially the 961s to 960s...works.
