I need help locating the test points TV9 and TV10 ona PCB 2060-810035
A WD 4TB hdd stays on BSY, and I need to short it.

TIA

Convert to SATA and then you can edit ROM (change zones for instance) and skip the bsy situation

Thanks for your time.
Let me give you some extra information on this case.
When connecting the drive, it gets stuck on BSY.
No clicking sounds

I am using MRT Equalizer.
Already extracted ROM, unlock it (with 411 disable), and wrote it back to the ROM chip.
But the drive still stuck at BSY.

That is why I'm asking for help locating TV9 and TV10 and see if I can force the drive to avoid the BSY state

I hope it makes sense

The MCU is a Marvell 88i1054-NXZ2.

This PCB has the same MCU:

Here are photos of top and bottom:

You can see TV9 and TV10.

Here you can see the exposed area under the MCU. The read channel is visible. You can trace the read channel pair to the underside of the PCB. They appear to be the two vertically aligned vias immediately to the right of the USB connector.

I think these are the read channel locations.
