This is an error in the check function related to the calculation of used blocks.
If this error occurs, the partition will be a full sector backup and the task will complete 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.
The file system of this partition cannot be repaired correctly.
This is a known issue.
