Case Registration

A client contacted us for help with his Seagate 2.5-inch 1TB hard disk drive, which had suddenly become inaccessible. While the drive appeared to power on and could still be safely ejected from his computer, it showed no lights and was not appropriately recognized by the system. When he opened Disk Management, the HDD appeared as "unallocated," which caused further concern since none of his partitions or data were visible. 

Assessment Result

Our recovery team performed a detailed assessment of the drive to identify the root cause of the issue. Although the device still appeared in Disk Management, we confirmed that the underlying problem was related to hardware. Specifically, the read/write heads were degraded and physically weak, which prevented access to the data sectors.

This type of failure can be particularly risky, as further attempts to use the drive in this state could easily lead to platter scratches and permanent data loss.

Data Recovery

Once the problem was identified, our engineers proceeded with the recovery in a controlled environment. We were able to access the data sectors without causing damage to the platters, and the recovery process was completed successfully. All of the client's data was retrieved in its original structure.

Data Checking

Our client arranged an online data verification session to confirmed the recovered files. He expressed relief and satisfaction with the outcome. The data was then securely transferred to a new hard drive for collection.

Conclusion

A drive that appears in Disk Management as unallocated may be suffering from partition corruption, file system issues, bad sectors, or even physical hardware problems.

Continuing to attempt DIY recovery or repeated usage in such cases can make the situation worse. If you encounter a similar issue, we strongly recommend stopping all use of the affected drive. Contact us, a professional data recovery service in Singapore, to maximize the chance of a successful outcome.
