Case:
Customer name: Siemens Company’s hardware operating environment: Seagate 7200.12ST3500418AS software operating environment: Winxp file system: NTFS fault phenomenon: Customer adopting measures: Directly sending data recovery company data recovery process received after the after -disc engineer detection and found that the sound of hard disks was very sound.Normal, the hard disk has been busy, not ready.Read only the mode by checking the firmware and the firmware.Can’t be written, and the firmware and magnetic head have serious faults.You need to open the market for the magnetic head and repair the firmware.
Solution:

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.Data recovery result: recovery success
