Partition prompts formatted data recovery successful

Case:
The 320G desktop hard disk has a total of 4 partitions, one of which cannot be accessed, prompting formatting.After many years of photos, I hope that all can be restored.

Solution:
The engineer found that the hard disk had no physical problems through professional equipment testing.An analysis of the disk editing tools found that the system structure of the fault partition file system is incorrect, so it is prompted to format it.The structure is corrected by manual computing, and all the data of the partition will be restored.
