Being stupid I used a power cable from a wrong PSU (Corsair cable with an EVGA PSU) and fried a HDD. Two, actually, because why not do risky things on two drives at a time, especially if they serve as each other’s backup. Not a complete backup, I am not THAT stupid, important stuff was elsewhere. But I’d be glad if you could recover less important stuff too.
I see that there are very knowledgeable people here, so maybe you could help.
Both were 2TB WD drives.
Yellow WD2003FYYS has big burn marks on major chips so probably hopeless?
Red WD20EFRX looks healthier, no visible burns.
Here is the picture of the Red’s PCB.
R43, R60: over limit
D1: 0.8 ohm / 0.8 ohm
D2: 33 Kohm / 0.8 Kohm
D3: 0.8 ohm / 0.8 ohm
D4: 33 Kohm / 0.8 Kohm
So, two TVS diodes per voltage rail? And should I remove D1 AND D3, and replace R43 and R60 with a blob of solder?
Any advice very welcome. Hopefully from @fzabkar - who seems to be very knowledgeable and helpful
