Case:
Pick up the power supply and find that there is a rustle on the board and then squeak, and the hard disk stops.
Solution:
Get the data recovery center of the hard disk line data recovery center to conduct a test before the data recovery, and the power supply is found to have a rustling and squeak. The hard disk stops. This shows that the magnetic head cannot read the content of the hard disk servo area, because a hard disk can The normal working status is to perform a built -in micro -code program built -in micro -disk after starting power, and this program is to control where the magnetic head reads the data, which paragraph is to avoid the dish. What is the capacity of this disk? Wait, if this information is incomplete, or the location of these data is a bad sector, which causes the magnetic head to be unable to read the data, so it will cause the magnetic head to work or abnormal noise during power. But if the magnetic head has been worn for a long time. It will cause two major types of faults. One is the excessive wear of the magnetic head, and the other is that the magnetic head is completely damaged. Generally, if the electromagnetic head appears, the vapor is usually completely damaged by the magnetic head. The indicator light in the PCI3000 after the detection disk was not ready and could not be returned. Therefore, the engineer of the line data recovery center can be judged that the Hitachi notebook hard disk must be opened to replace the magnetic head to read the data, so After finding a type of magnetic head matching accessory disk in the center of the data recovery center, after determining the failure and solution of this hard disk, after replacing the magnetic head of the fault disk in the ultra -net room, using the DE data recovery function of the UDMA to make the function to make the use After the mirror, after connecting the system, it was found that the data was 100 % completed.
