Answer:  The Oracle docs note this on the ORA-19566 error, indicating a media corruption error. 

ORA-19566 - Exceeded limit of %s corrupt blocks for file

Cause: The user specified limit of allowable corrupt blocks was exceeded while reading the specified datafile for a datafile copy or backup.

Action: None. The copy or backup operation fails.  The session trace file contains detailed information about which blocks were corrupt.

For complete details on investigating the ORA-19566 error, see MOSC note 336133.1.
