Case:
The customer responded to the computer’s normal blue screen when the computer was used normally, and then restarted the hard disk.
Solution:
The hard disk of Hitachi 160G first found that the hard disk was powered on the hard disk without response, and the motor did not turn. It may be burned by the circuit board. So use the same model of the spare parts to replace the circuit board, and the hard disk is directly knocked on the disk after power -on.At the same time, the hard disk magnetic head was burned out. Therefore, the magnetic head operation was replaced, and the magnetic head was replaced with a level 100 dust -free workshop. The hard disk was correctly identified. Then use the PC3000 Data Extractor UDMA to backup the data. The data recovered successfully.
