Burnt element on the drive board?

Question

Electronics

Due to the mixed up power supply 5v and 12v, 4 sata drives burned out (hung on one wire)
I don’t rummage in electronics, I unsoldered the burnt element, what is it, and where can I find a replacement?

Marked in the photo, a black square, 5 legs above and below.

Answer 1

This is some kind of microcircuit that could be found by the marking on the case, if it is still readable, or look for a diagram of this drive (which is not very real), or at least a photo of the board of the same drive (which is sometimes real).
But most likely, the matter was not limited to her, and you should not expect that the repair will make sense ...
