Does the SSD get ready on your PC3000 Portable unit? Or ready with error? Or BSY?

Not very popular model drive yet, so solutions at very limited, especially since it is USB based.

Some of these are supported some not.

It’s a newer controller that has in internal USB bridge in the controller, so has to be recovered via USB.

Measure the voltages at the test points (TPn).

I can't make out anything in the blackness of the first IC. I expect it's an e-fuse.

when I jump it into safe mode I get this

on the efuse

1 - 4.93

2 - 0

3 - .93

4 - 0.61

5 - 5.05

[pbzcbf...@gmail.com]

The e-fuse is the DFN component at U3. It must be OK, otherwise the board would have 0V everywhere.

The 0.9V, 1.2V and 3.44V supplies appear to be OK.

AFAICT, the hardware is OK. It does look like a firmware issue.

Thanks for the great info

Maybe I hardly misreading something, but it looks like the pin 1-5 voltage values are belong to one of the SY8089 buck converters (Probably U7 ?) and therefore I just wonder why is only 0.61V on pin 4 (IN) because it doesn't looks healthy. Could it be a selective suspension, or a missing 2.5v VCC for the YMN09TC1B1JC6C due to a partial short, or just a miswrote?

And .93 on pin 3 means 0.93 or 4.93? The output is surprisingly higher than the input, despite of that it is not a boost converter.

He mistakenly swapped pins 4 and 5.

[pbzcbf...@gmail.com]

... and 0.9V is the Vcore supply for the controller.

So a miswrote, it makes sense, thank you!

Yes, these are adequate voltage values.
