Case:
A mobile hard disk with a capacity of 500G is HD-PE500U2. During the use process, the problem of reporting the hard disk read is wrong.
Solution:
The engineer evaluated the degree of damage to the hard disk motor.According to the requirements of the motor number matching requirements, select the appropriate hard disk spare parts, and replace the motor and magnetic head in the dust -free room (actually replace the hard disk cavity). After the replacement is completedIn the process of hard disk mirroring, encountering bad sectors (often appear in actual cases), the corresponding bad duct solutions must be adopted to control the equipment safely and quickly to read the hard disk data;There are inconsistencies in the file system in the image, and the solutions of the corresponding file system damage are fixed until the data required by the user is migrated.
