Case:
The hard disk on the computer on Mr. Li is WD1000G who is copying the data in the mobile hard disk. Suddenly the computer is restarted by the computer. After the computer is restarted, it is impossible to enter the Windows operating system. Pressing the RESET key is still the same failure.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.The customer said that he wanted to restore all the data in the hard disk, so he contacted the data recovery company: http://www.fixhdd.cn/lxwm/sz/sz/
Solution:
According to the information described by the data recovery center, the engineer of the Data Recovery Center gives priority to testing whether the circuit board has burned or overcurrent. After testing, there is no failure in this aspect of the circuit board, and then the opening of the level 100 dust -free platform is performed.The discs were not scratched, and the initial diagnosis was that the magnetic head of the hard disk was damaged.The engineer of the 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.
