New Power Supply took My unraid server HDDs out.

[Autohaul58]

I made a rookie mistake when I upgraded my UNRAID server power supply. Swapped out the PS but not the cables. Knocked all 12 of my 4TB drives out. None appear to be burnt, but I'm sure all the PCBs blew a diode. I have already ordered new replacement HDDs. I need to be able to power up each "fried" drive and copy the data to one of the new HDD. I need some help determining which diode is the problem. It is my understanding that I might be able to remove the bad diode and then get the HDD powered on so I can copy the data to new drives.I will try to attach pics and records of what I got on the cards with a multimeter. My readings form this PCB were:
For the ORANGE circle
RED OL Black
Black .120 RED

For the BLUE circle
RED .868 Black
Black .119 RED

For the RED tirangle
RED .115 Black
Black OL RED

for the Yellow star
RED OL Black
Black .115 RED

My other cards have more info printed on them identifying D1,D2,D3,D4 ect. I can post those pics and readings.

Measure the two fuses marked "S". The one on the right will most probably be open circuit.
