This is an error in the check function related to the calculation of used blocks.
If this error occurs, the partition will be full sector backup and the task will be completed successfully.
However, a correct full sector backup cannot be taken due to a bug in the code.
If you restore a backup image that had this error, the file system for that partition will be corrupted.
Even if the file system of this partition is repaired, it cannot be repaired correctly.
This is a known issue.
