Hard disk bad sector data recovery ST3500320AS

Case:
The Seagate 500GB hard disk has been used for a year. When the problem was just wrong, the partition could be opened. Only a small part of the data can be copied. Most data can try to copy and cut it.It has been long for a long time, and now I can no longer recognize the partition.

Solution:
After the narrative of Mr. Wang, the engineer, the engineer conducted a preliminary test, which could be determined as a fault caused by a physical bad sector. The magnetic head No. 1 2 was aging. At the beginning, it was not so serious. Later, Mr. Wang’s operation was on the hard disk.There are also certain damage, the bad sectors have spread, and the magnetic head is a bit unstable.It is much more troublesome to recover than Mr. Wang’s operation before the operation. You can only use the hard disk bad sector recovery tool to perform the sector mirror of the disk, and then recover the data on the mirror disk. About 10 hours, the data recovery is successful.Data recovery rate is 98%.
