Case:
Customers first called the company to consult, saying that the hard disk was broken, and whether the data in the hard disk could be restored. The engineer was caused by the preliminary diagnosis of the hardware in the hard disk through the exchange on the phone.The details are that the hard disk has abnormal noise and does not read the disk.
Solution:
Judging from the sound should be that the magnetic head is trying to reset, but it cannot be reset because of stuck. After opening the disc body, it was found that the magnetic head was stuck. When communicating with the user, the user mentioned that he had tried many times and used different power supply to perform power supply test. After hearing these descriptions of the user, I feel that this case will not be just a simple problem. The magnetic head is directly reset and the electricity is used to power again. It seems that the same as it is inferred, there is a problem with the magnetic head or the firmware area on the plate. Change the magnetic head directly, find that the fault disappears, and can identify the hard disk normally. I thought that the failure of this step was resolved. I did not expect that according to the path provided by the user (the user installed as Vistar, the user reported that the data was stored on the desktop) and did not find the corresponding data. There is no error in the process of explaining the C area with DE. It is estimated that it is likely to be a logical problem. Because it is a scheme that uses the magnet to replace the magnet, first uses DE to perform a mirror and then scan. First find out the bitmap of the logic C drive (NTFS) and then use a small tool BitMapsan to scan the cluster of the logic area. In this way, only the cluster of the cluster is needed when DE, which will greatly speed up the speed of DE. After 4 hours of mirror logic C drive, the cluster mirror is finished, and the data required by the user after scanning with RSTUDIO is scanned. It is strange that the content scanned by RSTUDIO has 4 copies of each folder. I don’t know if it is There are still any other problems in the virus. Because the time is too urgent, it is not studied. Whoever encounters this situation can be studied together. At this point, the data recovery is successful!
