Number of bytes which can be C1 error corrected when error was detected.
As the error byte number cannot be determined for blocks which could not be corrected, the
bytes are not added for random error.
The number of blocks which could be corrected are calculated from the C1 burst error.
00 (Hex) is 0 byte when it could be fully corrected or could not be fully corrected.
Normal value 00
