I really think you need to be fixing the patient board.

Assuming the motor IC is the same - why not remove it from the patient check for a short, replace it with the donor and check for a short.

Did you ever resolve your issue?
I am experiencing precisely the same symptoms - no spin.
I have gone over my board referencing each post in this thread and voltages at all test points are identical to the patient board referenced here.

Just FYI, the dual e-fuse on the OP's PCB is an MP5094. It is pin compatible with the STEF512.

MP5094, Monolithic Power, Dual-Channel 12V/5V Current-Limit Switch with Output Over-Voltage Clamp, marking AYUy, TSOT23-8:

Is it possible that SATA power pin #3 was supplied with 12V rather than 3.3V? This is the DevSleep pin. I think it is connected to the MCU. I would measure the voltage on this pin.

Sata Pins 1-3 all measure 0V. But, I also tested several Sata adapters I have here and they all do not provide 3.3V on pins 1-3. The do provide 5V on 7-9 and 12V on 13-15

If you connect the PCB on its own, do you see any sign of it in BIOS or Disk Management or Device Manager?

If you slip a business card between the PCB and the HDA pads, does the drive spin up?

The board alone inserted in a Kingwin adapter does show up as /dev/sdc in linux

root@TR-DR-2:/home/tr# lshw -C disk
*-disk
description: SCSI Disk
product: EZD-2537U3
vendor: KINGWIN
physical id: 0.0.0
bus info: scsi@6:0.0.0
logical name: /dev/sdc
configuration: logicalsectorsize=512 sectorsize=512

But, it does not show up when connected to an eSata port I commonly use.

And, it does not spin up when the 22 pin HDA connector is insulated.
No voltage on the 4 motor pins either.

I noticed that the OP was using a donor board with one BIOS chip instead of three and wonder if that affected his results.
I have ordered the correct donor board due to arrive in a few weeks from China.

When connected via USB, the OS is seeing the USB-SATA bridge firmware, but not the HDD behind the bridge.

The OP's PCB was able to report the model number via SATA, so that would suggest that your board's MCU is not responsive.

When Patient PCB with its ROM connected with power and sata => No Spin, but shows Model Only, No Err LED
When Donor PCB with Patient ROM connected with power and sata => No Spin, Shows Model Only, Err LED

I understood that you wanted me to report behavior with board disconnected from the drive. I think the OP was giving results of the board and drive unit together because he was saying that the drive did not spin.

Yes, maybe I misunderstood. I'm not so sure now. You could always try this with your replacement PCB when it arrives.

So, I just received a donor board today, transferred the three bios chips and there was no change.
The drive is still completely NSOL.

Seems like our boards have been good all along and maybe the motor is blown?

You can check if it's blown via the windings.

Did you try the donor PCB before you transferred the ROMs?

I did not, but I will, and report back.

How would I do that?
I do not have an ISO room but I do have a very clean environment ( :) ) and have opened up many drives without dust issues to do head swaps and even a few successful platter swaps.
My main obstacle is that I have to wear a mask so I don't drool on the platters when working :).

The spin motor has 3 windings ("phases"). Measure the phase-to-phase and phase-to-common resistances using the 200 ohms range of your multimeter. They should be around 2 ohms and 1 ohm, respectively.

Code:
                 Common
                   o
                   |
                   |
             +-----+-----+
             |     |     |
             |     |     |
             C|    C|    C|

How - is as per fzabkar's instructions, Where - is from the outside of the drive where the motor contacts for the pcb are.
