Wd5000h1u - 00 - - Burny Plug - Plug or Unit Died?

Hello,

My external WD hard drive has stopped working.

I believed either the plug or the unit overheated as the electrical plug has a burnt type smell. When j open the plug using the clip, there was what I can only describe as sweat, perhaps formed as condensation after the plug overheated.

When the unit is plugged in, the WD hard drive appears to be blinking blue rapidly.

I assume either I need to replace the plug or the power unit inside the device no longer works.

If its the plug, where can I get another? Always prefer to get a proper WD one than a cheap one off amazon or ebay…

Thanks
Alex
