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!

Can anyone help me out!

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


Here is inside the utility with ROM pin shorted

There is no short.

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?

I will get a donor SSD soon. I will test it out on the donor
But i'm pretty sure that something is shorted

because the light indicators on PC3000 Portable Pro only shows that way when there is a short on the board. If the board is not shorted the light should came in BSY if there is a problem with Firmware of the drive

Just get your multimeter and measure those test points that I asked for. I suspect that you tested the Vcore bypass capacitors on the continuity range of your meter. This range often has a threshold of 100 ohms. Any resistance less than 100 ohms causes the meter to beep. An ARM core typically has a resistance of 100 ohms, so that is probably what you were measuring. Nothing else makes sense to me.

Here are the voltages at the inductors

Oh and resistances of the inductors from left to right are 210 ohms/ 510 Ohms / 510 Ohms

The voltages and resistances appear to be OK.

The 1.0V supply is Vcore. A resistance of 210 ohms seems normal for an earlier core.

I have seen a 2.9V NAND Vcc supply in other SandForce SSDs, so that is not unusual.

In your earlier images you identified "shorted" capacitors. A short measures 0.0 ohms, or close to it. I can't see how that is consistent with your latest measurements. :-?
