Case:
The peers took a Samsung hard disk for data recovery, and the failure of the hard disk did not recognize the disk.
Solution:
The PC3000 using the data recovery device is further tested for the hard disk. As a result, the hard disk cannot be recognized. After power -on, the hard disk has a knocking sound, which may be a problem with the hard disk magnetic head.So use the same type of spare parts to open the market and replace the magnetic head on the dust -free table. After the magnetic head is replaced, the PC3000 is accepted for detection, which can be identified normally.
