Case:
When the mobile hard disk is inserted on the computer, the crash will appear, and it will be fine again.I checked it with the software and found that there were many bad channels.There are some important drawings in it to recover.
Solution:
It was tested by our company’s engineer and found that there were more bad sectors of the hard disk.So the engineer used professional equipment to perform physical mirrors to the disk, and then used professional data to recover software to extract the bottom layer of the hard disk, and the final data recovered successfully.
