Solution:
According to the customer’s description, the initial judgment of the engineer of the data recovery center is likely to cause the circuit board to burn the circuit board, so the circuit board of the hard disk was detected, and the voltage problem found that the circuit board was short and BIOS burned.So the same model of the circuit board was found for replacement. After the replacement was completed, the power was turned on to normalize the hard disk, and it was burned in the magnetic head.Data is directly DE, and the data is successfully recovered successfully at this time.
