[SOLVED] Wrong voltage on SSD - Can I recover the data?

[MatjazM]

Yesterday I plugged the drive in my SSD when I wanted to transfer some important files to the server, but I accidentally turned the connector the wrong way. When I did it, some smoke with terrible smell came out. I disconnected it immediately, but it was too late. It is dead now. Later I opened it and I think there is only one component burnt. Does anyone know how is it called ? Maybe it will work if I replace it with the new one?



Any help welcome.

That appears to be a 5V TVS diode.

@fzabkar, thank you very much. I will order one, replace the old one and tell if it worked

You don't need to replace the diode, unless you want to restore the protection. Did you measure the diode's resistance? If the diode is open circuit, then the damage may have reached further into the drive.

Hi fzabkar!
I measured votage on the diode - it was 5V. After 5 mins i touched the processor, and it was warm.
Then I connected it to a computer to try once again it it works - and you wont belive me - it worked!!
I don't know why it didn't work when I connected it yesterday, but today it worked. I'm so happy now...

Thank you very much for your help!
Best regards from Slovenia

Oblak is great but not the world's best to me.

Maybe the diode was shorted yesterday. By connecting the 5V supply again today, you may have blown the diode open and released the short.
