Case:
The customer’s personal computer has not been able to power on several times, and then send it directly to the data recovery center of Room 1309 in the Bailihui Computer City.
Solution:
After receiving the disk, it is found that there is a regular bad duct through professional tool testing. This kind of failure is generally a magnetic head damage. In order to correctly judge the fault, we hung the disk on the UDMA to test the head.The division is: 0,1 ,. 2 magnetic heads.After the test was completed, it was found that the number 1 was wrong, 0, and the number was intact.First use the head processing, mirrize the data on the No. 0 magnet head first, and then find a good disk of the same model for a good head to replace the magnetic head. After replacing the good magnetic head in the clean room, hung the plate back to UDMA to cancel the head 0.Read only at the beginning of No. 1, and the customer’s data through the mirror time of about 2 hours has been restored.
