Case:
Customers’ Western Digital hard disk faults are a large amount of physical and logical bad tract caused by the aging of magnetic heads. The 500GB space of the hard disk is relatively large, so the bad sector spreads very fast. The customer can open the partition at the beginning and try to copy the data many times, but the copy cannot be copied out., And also led to severe diffusion of the bad sectors. When the hard disk was obtained by the data recovery center, the partition could no longer be recognized.
Solution:
According to the bad sector, the engineer determines the disk defect caused by the aging of the No. 1 head. The recovery plan is determined to be recovered by UDMA. This can ensure the security of customer data to the greatest extent.After it is completely, the disk mirroring of the No. 1 magnetic head is performed. The UDMA tool has a shaving protection function. The maximum guarantee to ensure that the magnetic head will no longer be damaged during the recovery process. It also increases the success rate of data recovery. The total recovery time is 16One hour, the data recovered successfully.
