RMAN - ORA-01578| ORA-26040: Data block was loaded using the NOLOGGING option

Recovering NOLOGGING Operations 

Scenario:

We have have taken full DB backup and created table with no logging option after rman backup , So crashing DB by deleting all datafiles at os level.
We can see after rman backup restoration when executing query of no logging table it will throw error.
So need to recreate table again and take backup again.

Error:

ERROR at line 1:
ORA-01578: ORACLE data block corrupted (file # 7, block # 4627)
ORA-01110: data file 7: 'C:\APP\TEST\ORADATA\TEST1\USERS01.DBF'
ORA-26040: Data block was loaded using the NOLOGGING option


Recovering NOLOGGING Operations
