What SMD component is this?

Hello,

     i am of the opinion that the its the PCB that cracks its internal layers and board stops working  .For a swap i think MCU + Rom is more then enough

I'm working on a case very similar. Original USB was working fine and I was using MRT Stabilizer card on top of it.

I needed to isolate PCB from heads and probably I bend it a little and after that it doesn't spin up anymore.

If I use a SATA PCB, I can access FW, etc, etc, but since it's encrypted by MCU I can't get the data out.

I have swapped MCU, ROM and the 2nd ROM and still doesn't spin up....

What can I do more??

Here is a discussion about a similar PCB with the same Redfin motor controller:

The user has provided most of the voltage measurements.

I will pick this up again soon. The client with the bad PCB decided not to go ahead with the recovery so took my source material.
