Samsung 500GB hard drive has bad sector recovery case

Case:
After the customer’s Samsung notebook computer is turned off normally, it can be used to use the boot to enter the operating system again, and there is a problem with the hard disk.

Solution:
After 3K for testing, the hard disk can be identified and read the firmware, and there is no problem with the magnetic head. There is a bad sector in the scan and found that the copy is made directly. After the copy is done, I use Winhex to open the analysis.Fill in the MBR record, the data is normal, and 100%recovery.
