Where can i get a replacement circuit board for my hard drive - i think its fried

Hi Guys,

I have a WD800ADF0-75NLR1 internal HD that seems to have fried the circuit board. HD got too hot i expect. HD can get identified in the BIOS (sometimes )but not in Windows. No clicking sound off HD.

Any ideas where i can get a replacement board please or other fix? Cables are tested and fine.
