LAG IELD EFINITION
No Error information will be included in the data stream.
The C2 Error flag (Pointer) bits (2352 bits or 294 bytes)
will be included in the data stream. When the C2 Error
pointer bits are included in the data stream, there will be
one bit for each byte in error in the sector (2352 total).
The bit ordering is from the most significant bit to the
least significant bit in each byte . The first bytes in the
sector will be the first bits/bytes in the data stream.
Block Error Byte will be included in the data stream.
The Block Error byte is just the longitudinal parity of all
the C2 Error Flag bytes, So that the data stream will
always be an even number of bytes, the Block Error byte
will be padded with a 0 byte. The Block Error byte will
be first in the data stream followed by the pad byte.
Reserved for future enhancement.
