I have a Samsung G3 Station 2TB external hard drive (link to PDF specs here). It was working perfectly when I accidentally plugged it in my notebook's power source. Now, it doesn't work even with the correct power source. The indicating led, which previous to this accident blinked when the HD was accessed now blinks ininterruptly.
The notebook's power source is 19V/3.42A. The hard drive's is 12V/2A and I know that, inside its case, there is regular 2TB SATA drive, along with some sort of adapter.
Does this adapter has some kind of power protection? I opened the case and the hard drive board smells bad. The adapter's does not. Is my data forever lost or can I replace its board?
Does it not work now with the correct power source? – Amicable – 2012-04-12T16:17:31.120
1Try putting the hard drive into your computer internally and see if it's seen by bios/os – Rob – 2012-04-12T16:28:01.793
The power input of the enclosure goes to two places: 1) the 12v SATA power input, and 2) a DC-to-DC converter to derive the 5 volts for the USB-to-SATA adapter and the 5v SATA power input. The DC-to-DC converter and the HDD spindle motor are the most likely components to be damaged with 50% overvoltage. If the converter passed the overvoltage downstream to the logic boards, then both the USB adapter and the HDD controller boards get fried. – sawdust – 2012-04-12T20:10:05.730
