Burned Chip
You smell smoke and notice a burned microchip on your hard drive. Don’t panic it’s not the end of the world. We’ve seen this many times. The read write heads and the circuit board, which is also called the logic board connect to each other using a small access port located on the underside of the drive. This means that what can happen to one can also happen to the other. Sometimes the burning of a chip can also damage the read right heads because of their connection. 
 
To repair this problem you will need a rework station with capabilities of microscope assisted soldering. You will also need a clean room to swap heads in case the read write heads were effected.
