Solution
The circled part is a 12V TVS diode. You can substitute an SMBJ12A or equivalent.

That said, if the diode is shorted, then you will need to examine the 3 small inductors in series with each of the +12V SATA power pins (above the 2R00 resistors). If these inductors are burnt or open circuit, then you will need to bridge them with a wire link.
