Case:
One model is ST320418AS 320G Seagat’s mobile hard disk inserted into the Windows operating system computer. The computer is stuck, and other operations are not performed. There are important files to be copied. After testing by engineers, there is a physical bad channel for the hard disk.
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.
