This type of recv is used to heal corrupted data when a replica of the data already exists (in the form of a send file for example). With the provided send stream, corrective receive will read from disk blocks described by the WRITE records. When any of the reads come back with ECKSUM we use the data from the corresponding WRITE record to rewrite the corrupted block.
