Hi
I have a dead Samsung MZ-VLB2560 , and are wondering if it possible to revive this nvme ssd. It died quite instantly I've been told, a warning from Windows( Dont know what), and then on reboot the controller didnt find the disk.

I have tried connecting the disk to a new nvme controller, but to no avail.

What do you think, it is possible to do some phyiscal debugging on this thing? Can it be a short or dead component?

I noticed that it gets really hot, but I have no benchmark on the temperature, so I really dont know what temperature it runs at while idle, but I doubt it should get _that_ hot while idling. It's the ARM MCU itself that gets really hot, but I'm guessing a physical fault, not a software fault causing overload and that heat.

Use the ground pins at the connector.
