Hard Drive power connector melted

Daniel Marshall · May 4, 2014

Yesterday I put my Hard drive back in my PC after using it to see if another motherboard I'd scavenged worked. Once I'd put it in and turned my PC on I went to get my laptop from the other side of the room and when I looked back there was smoke billowing from my case. I immediately switched it off at the plug and opened up my case to see what had happened. It turns out that the power connector to my hard drive had shorted and now I cant use my hard drive. Is it possible to fix the hard drive? Thanks in advance.

Hi Daniel Marshall,
try the HDD on your laptop again and see if it works , provided the power socket is not damaged
the question should be what caused the HDD power connector to melt ?
what PSU do you have in that case ?

The connections on my HDD are ruined so thats not possible also I have now cut off the power connector and blanked the wires so I can use another connector instead. Plus I'm using a CoolerMaster GX650W PSU

The HDD was probably damaged by an overvoltage from the PSU in which case there will probably be a shorted TVS diode on the HDDs PCB. Depending on the model, there may be an easy, no-cost DIY solution.

Can you show us a photo of the damage?
