Case:
A client’s Western Digital hard disk fault is a large amount of physical and logical bad tract caused by the aging of the head. The 1000GB 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 does not not copy, but the copy does not copy the data, but the copy does not copy, but the copy does not not copy, but the copy does not copy, but the copy does not not copy, but the copy does not copy, but the copy is not available.Come out, and also causes the bad duct to seriously diffuse. When the hard disk is obtained by the data recovery center, the partition can 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 has been completely, the disk mirroring of the No. 1 magnetic head is performed. The UDMA tool has the function of shaving the head. 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.It took 20 hours to restore, the total recovery time was 34 hours, and the data recovery was successful.
