Does anyone have specific information about the protection
device
at the power supply inputs of hard disks?

I assume that it's a zener diode or something similar in

Could be. In fact, I mentioned that in my second post. What I
find surprising and frustrating is that I have not been able to
find any data on the BUX C*** series.
