Fault Description:
After communicating with the customer, it was found that the system failed to boot after a sudden crash during restart. The user could not access any data and needed urgent assistance.
Data Recovery Process:
The data recovery engineer used MHDD software to test the hard drive. The drive was recognized correctly in terms of model and capacity. However, during sector scanning, some sectors were readable while others were not, following a regular pattern. This is a common issue caused by a damaged read/write head. When the faulty head attempts to read a bad sector, it becomes unreadable, leading to data loss.
After confirming the issue with the customer, the engineer began the recovery process. First, the drive was connected to a UDMA data recovery machine. A split operation was performed, and then the good magnetic head was mirrored first. Once the good head image was completed, the hard drive was removed and replaced with a functional head assembly in a 100-level clean room. After debugging and sealing the disk cover, the UDMA machine was used again to mirror the previously damaged head. Once this process was complete, all the data was successfully restored. Image:
Data Recovery Result:
100% of the data was recovered successfully.
Darth Data Recovery Advice:
We strongly recommend backing up important data regularly, especially for older drives that are more prone to failure. If you experience data loss, it's best to seek help from a professional data recovery service. Attempting DIY recovery can lead to further damage. Always trust experts when dealing with critical data.
