In any case, @unknown has already stated than an SSD PCB swap does work.

Yes, tested.
Without any modification.

Was the patient's data contaminated by the donor's cache???

The drive back to work with it's data inside like a brand new.
It was in a Lenovo laptop.

The drive starts but gets stuck in bsy state if i removed the SSD board. However, attaching it live makes it get ready. pepe

Mine is quite the opposite. It starts without the SSD board. If i attach it live it goes BSY. If SSD board is connected from the beginning drive always BSY.

What is under the 771980 sticker on the main PCB?

Hynix H5PS5162GFR-S6C - 512Mb DDR2 SDRAM

Marvell 88SE9171 - One-Lane PCIe 2.0 to One-Port 6 Gbps SATA I/O Controller

Marvell 88i9441 - Soleil-H SATA SSHD Controller 6Gb/s SATA, Dual ARM On-Chip Processors, Encryption

WD REDFIN A11SP - Motor Combo IC

Winbond 25X40CLVIG - 4M-bit 2.5V Serial Flash Memory with uniform 4KB sectors and Dual SPI

The SSD SATA lines come out of SSD

Than go to the other side of PCB into the connector

Than to the main PCB and into Marvell 88SE9171 chip.

I could not find where the main SATA port lines go even thou i beeped all the components and pads on the pcb.

In addition to the SATA Tx/Rx differential pairs, there appear to be two signals connecting U8 ("3CTCTN") to J7. I don't know how, or if, these extra signals would affect "cheating".

UPDATE

Cheating with HDD connected instead of SSD did not work.

I finally got SSD pcb replacement and it worked like a charm.

That's what I was talking about.

Good job.

Hi,

I have the similar patient as yours. Drive always on Busy when power up. When you said SSD PCB replacement, Did you swap anything from the patient SSD PCB to the donor SSD PCB? Or you just swap the whole SSD PCB?
I tried swapping;
1. SSD PCB only - busy
2. SSD PCB and SATA PCB with patient ROM (U12) - also busy.

I tried both method and it didnt work as well.

Maybe your problem is not SSD related.
