Case:
At first, I could open the partition and tried to copy the data many times, but I couldn’t copy it. Now I can’t recognize the partition.
Solution:
Customers have tried to copy data many times, which cannot be copied normally due to the bad ducts, and the bad sectors have seriously spread, which increases the difficulty of recovery.According to the bad duct, the engineer determined that it was caused by the disk defect caused by the aging head of No. 1. The recovery plan was determined to be recovered by UDMA. This can ensure the security of customer data to the greatest extent.After the data has been safe, the disk of the No. 1 magnetic head is processed. The UDMA tool has a magnetic head protection function. The maximum guarantee that the magnetic head will not be damaged during the recovery process. It also increases the success rate of data recovery.After 30 hours of recovery, data recovery was successful.
