Case:
According to the customer’s description, the computer’s boot report cannot detect the hard disk, and the hard disk has an abnormal noise, and the after -sales detection is damaged by the hard disk.However, there are recent project drawings in the hard disk, hoping to restore hard disk data and retrieve the files.
Solution:
The engineer received the inspection of the after -disc engineer and found that the sound of the hard disk was very normal. The hard disk was always busy and could not be ready.It should be the Seagate firmware incident.After receiving UDMA, start repairing the firmware, but the SMART table is wrong in the process of fixedware repair. It is clear that the Smart also fails. The reason may be on the Smart. Generally, the failure of the magnetic head when it is cleared at 11:12 to clear the SMART.question.Try a lot of tricks or not.You can only open a magnetic head to look at it, and find a good disk of the same series and the same model from the spare parts library, and conduct the work of replacing the magnetic head in the ultra -net room.After changing the magnetic head, we hung the plate on UDMA and found that it was still busy. After entering the program, we started repairing the firmware. At this time, the Smart was reported successfully.After the exit program, the hard disk has changed from busy disk to a moment of adequate.The mirror bar quickly finished the entire disk with DE.The data is successful here.
