Crc[=Autodin_II]

    Uses the AUTODIN-II polynomial for the 32-bit CRC calculation and
    provides the most reliable end-to-end error detection. This is
    the default for NRZ/PE (800/1600 bits/inch) tape drives.

    Typing Crc is sufficient to select the Crc=Autodin_II qualifier.
    It is not necessary to type the entire qualifier.
