Western Digital hard disk head damage recovery case

Case:
A customer’s hard disk of WD320GB cannot be recognized.

Solution:
First of all, the hard disk was tested, and the hard disk was found to have a knocking sound after power -on, so it was suspected that the magnetic head was damaged, because the customer only needed a folder data of the D drive, so it was replaced with the same type of magnetic head.Flowers, if there are data that is stored in the mess, there is no way to recover if it is stored in the data that users want. Fortunately, there are not many data that customers need to recover.After replacing the magnetic head, the hard disk is found normally, so the data is directly copied by DE, and the data required by the user is just complete.
