I have a WD5000AAKS HDD which totally stopped spinning and providing power through numerous means all result in failure. The hard disk doesn't spins. Has anyone else faced this issue? If yes, what did you do to solve it? Or did you just sent it back under warranty?
I took off the PCB (HDD is out of warranty) and found a partially burnt but still functional resistor (330R) and a shorted TVS diode (on the +5VDC rail) which was also physically cracked horizontally and vertically. I looked at the label on the diode under a 10X microscope and it is STMicroelectronics GP 7S1 - no information or part match on any site. The WAPDA/IESCO voltage spikes :mad: have worked their magic and destroyed a perfectly good HDD. I wish a class action lawsuit could be brought against them but they are protected by law against such a lawsuit. :mad:
I have de-soldered the TVS diode and will be testing today if the HDD works without it or not. Ordering a replacement diode may take weeks from Farnell. Before I give it power, I want to ask if anyone has been successful with this method (apparently, lots of WD HDDS have suffered from this issue due to cheap lower quality manufacturing).
