Cool thank you for your input.
From what my brother and the people he work for, told me. If the diode has work as intented, it would have sacrifice itself to save the board. I also saw some video that people were using and hard drive without diodes to copy/mirror the data for recovery. From what they told me, running a hard drive without diode is a bit unsafe because, there would not be anymore second chance.

I will take some time to think about it, I only lend 2 drives to my brother so he can check them out with the people he work with and I am trying to RMA my original PSU. Also, I am doing investigation on the diodes replacements and PCB replecements.
Not getting my data back is not the end of the world, but there are some stuff that if I could get back, it would be nice. My ideal scenario, I could replace the diodes, copy my data that I care more about on something else and use these old drives this until they die (or better if they don't).
