Hitachi 320GB hard disk head failure data recovery case

Case:
Customer’s Hitachi 320GB hard disk cannot be charged.

Solution:
The problem of non -power power is generally concentrated on the circuit board. In some cases, the short circuit of IC in the internal conversion of the magnetic group will also cause no power to power, but this situation is very small.There is no spare parts in this disk, but there is a model of HD322HJ hard disk. View the main control IC of the circuit board.Although the reset is different from the fault disk model, it is only the difference between the fourth place and the two series series are the same. It is estimated that its magnetic head is also universal, and it is decided to replace the magnetic head directly.After replacing the magnetic head, it is found that it can be ready, and you can directly recognize the model (the circuit board is also changed), and you can browse the data directly into DE. So far, the data is restored.
