Samsung EVO 840 Terminal Connections?

[ddrecovery]

Anyone know/confirm where the terminal connections are on this Samsung EVO 840?

Read @sourcerer's "missing manual".

Read @sourcerer's "missing manual".

That is a great manual, but this is a PM862 which has an entirely different board layout with far fewer technological pins.

Sorry, I should have RTM.

Sorry, I should have RTM.

Not sure what RTM means, but I am assuming read my mind or something like that, so I apologize for not putting this in the first post. But I was hoping that someone who has had this drive before might know, hence the pictures. While it is called a PM863, it is an EVO 840 with an EVO 840 controller.

It is usually "RTFM" but in this case "Read The Manual"

All my searches turn up a different controller for the 840 Evo (S4LN045X01-8030 versus S4LP052X01-8030).

The PM863 is an enterprise model whereas Evos are "specially designed for mainstream PCs and laptops":

Thanks for the research. I was told that this drives FW is based on the EVO 840. I guess when Ace Labs supports it we will know more. Once again thanks for the research, its appreciated.

Hi,

I can only see the JTAG pins.
The pins you have marked with a question mark look more like test pins to me than UART pins, the UART pins have always been through-hole on the Samsung SSDs I have seen but hose are just SMD points, so I think Samsung could not plug in their UART connectors into those pins. Perhaps they have given up on the UART interface completely, since it's pretty useless with most of the firmwares I have seen anyway.
Which voltages do you measure on those 2 pins?
I guess you can only use JTAG interface with this model then.

[fzabkar]

That line of 7 test points looks like it consists of two groups -- a group of 5 and a slightly offset group of 2. Can we be certain that those 2 test points are the SAFE mode shorting pins?

[sourcerer]

Yes, those 5 pins are the JTAG and the other 2 next to them are the SAFE mode. Exactly the same pinout as on the EVO840

Is this the same SSD?

Probably. I no longer have this drive. The client is apparently hawking it around every data recovery company he can find. He says he needs the data urgently, so if the company cannot get his data within a day, he moves on to the next.

Coming to a data recovery company near you soon...................

AFAICT, your tools identify the controller incorrectly (MEX versus Mercury), so it would appear that it is not supported.

I am not sure what you mean?

[fzabkar]

840 Evo uses the MEX controller whereas PM863 uses the Mercury controller. If the tool is reporting that it has found a MEX controller, then how can it be expected to work correctly with your SSD? Perhaps this is why no CP can be read.

AFAICS, the PM863 is not supported:

I think you are referring to the post on a different forum. The tool we use is not the same tool as the images posted.

Heres ace response

Hello Wayne. Sorry for bad news but even in September Update I'm doubt that new loaders and new family of Samsung will appear in support list. Samsung developers starts to protect their drives with very tough encryption, and if in Samsung 840 EVO / PM851 it was possible to work through terminal, in next generation - 850 EVO / PM861 / PM871 they remove terminal interface from SSD at all. As the result we can't communicate with drive and can't reach TechnoMode on it.
I'm afraid in nearest 2 years we will not get any solution for it.
