Need your guys help!
I have this SSD ADATA SP900, It is shorting everywhere. By getting to ROM mode. Controller works fine (Sandforce SF-2281VB4-SPC).
Can anyone provide measurements for the drive. And what can be faulty?
Many thanks!

Examine the terminal log.

It's obviously not "shorting everywhere".

Yeah, but i mean the short is what makes the drive to not work

Here is the power without ROM pin shorted

I should have said there is no short in your PC3k screenshot. Those areas you have marked out are capacitors. These are powered from the two DC-DC converters, U5 and U6. Measure the voltages at the inductors.

The fact that your controller identifies itself in ROM/safe mode suggests that its Vcore and Vio supplies must be OK, so that contradicts the claim that its bypass capacitors are shorted. Are you relying on a beeping multimeter, or are you actually measuring these resistances? What are the resistances between ground and each of the inductors?
