Case:
The customer’s PC uses a 750G ST hard disk, the Windows operating system. At one time, the customer found that the system started slowly, and the partition was very slow. Even the files could not be copied.Very slow, the files are still unable to copy. Among them, a large number of video files need to be rescued. After the engineer uses professional equipment testing, it is caused by a physical bad dish.
Solution:
The engineer evaluates the degree of damage to the physical bad sectors of the hard disk.When reading the hard disk again, focus on the sector that is not seriously damaged, and provides higher integrity for the recovery of hard disk data.Continue to control the data blocks that have not been read before repeatedly, and check the lack of recovery of the previous recovery work, and make the data block read as close as possible; conduct logical analysis and verification of the full mirror of the hard disk backup of the device.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.
