A faulty WD 10TB Gold HDD and a successful repair attempt.

I received a Western Digital Gold 10TB HDD to investigate why it suddenly went bad. After the repair, I was still left with the question of what could have caused the fuse to blow and the control panel to remain functional. A momentary voltage surge that the suppressor diode protected against? Or user fault? If you liked the video, please subscribe.

I think the part you installed is a zero ohm resistor, not a fuse.

Maybe, but there are manufacturers who use the "O" symbol for smd fuses.

Unfortunately, I could not identify the original "XH" or "HX" mark, it can be fast, slow, pulse-resistant, resettable, from 1.5A to 5 amperes. SMD coding is a mystery. For sure, I have already ordered a new 2A fuse, I hope it will last a long time.

Yes, this was a zero ohm resistor. I replaced it and then tested it with lab power. It hasn't burned out from 10A yet. 🙁
It seems that they were only used as jumpers in Fujitsu. 2:47
