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?
