Case:
Personal client’s computer hard disk has been charged several times and still cannot recognize the disk, and then directly send the data recovery center.
Solution:
After receiving the customer’s plate, removing the box is a hard disk of WD Western data. The self -inspection sound of the hard disk during detection is normal. It can be ready under the PC3K disk. We can conclude that there must be something wrong with the firmware. After continuing to enter the program, we started to detect the firmware to see the problem. When we detect the firmware, the firmware does not allow access, and the two methods of ID ABA cannot be accessed. It is troublesome and may be complicated. Write, when you look at the magnetic tract, it can be read normally, then it is easy to handle. Let’s read the last 3 magnetic trails and microbences of the disk first, so that it can be analyzed, and the problem is there. After half an hour of magnetic tract analysis, we have found the problem that the 40 module is damaged, and the No. 40 module is that the data adaptation module cannot be replaced. In routine, the damage of modules 40 will not cause the firmware to be accessible. There is no clearness. Maybe this is special. Regardless of this, let’s repair the 40s first, and finally use the software to modify and adjust the important position through the software. Finally, the 40 modules are finally done. But now the firmware cannot be accessed, and it must not write the module directly. We can only adjust the 40 modules on the magnetic tract to generate a well -produced magnetic trail, and we write the magnetic trail onto the hard disk. All the hard disks are normal under the power -off detection. There is no bad sector with MHDD scanning but there are some logical bad sectors. Data directly use PC3K mirrors.
