Case:
The client said that the computer was copying the information in the mobile hard disk. Suddenly, the computer was restarted. After the computer was restarted, he could not enter the Windows operating system. Pressing the RESET key was still the same.After that, the company’s computer administrator came to check and said that after the hard disk was started, the hard disk continuously made a knocking sound, and the diagnosis was damaged by the hard disk.Customers say that they want to restore all the data in the hard disk.
Solution:
The engineer of the Data Recovery Center, according to the information described by the customer, prioritizes whether the circuit board has been burned or overcurrent. After testing, there is no failure in this aspect of the circuit board. ThenThe hard disk dish is not scratched, and the initial diagnosis is that the magnetic head of the hard disk is damaged.The engineer of the Loying Data Recovery Center finds the hard disk magnetic head of the same parameter in the accessories library, and cooperates with the professional hard disk magnetic head replacement tool to replace the hard disk magnetic head on the level 100 dust -free platform.Using professional equipment PC3000 UDMA to power the hard disk, the hard disk is found to be normal, enter the PC3000 UDMA WD special mode, the hard disk parameter recognition is normal, and the important module is backup first, and then all the firmware is backup.Then open the PC3000 UDMA de process, the full mirror is completed, and there are a small amount of physical bad sector. Through Winhex analyzes the underlying data of the mirror image, the files in the location of the physical bad sector are repaired. The data has been successfully restored by 99.9%.At this point, the hard disk data is successfully recovered.
