The READ CD-DA MSF command requests that the drive transfer CD-DA data.

The data transfer length (bytes) is calculated as follows;

Data Transfer Length = [(Me-Ms) * 60 * 75 + (Se-Ss) * 75 + (Fe-Fs)] * CD-DA Block length

(Ms, Ss, Fs) = Starting MSF address (Me, Se, Fe) = Ending MSF address

NOTE: The drive transfers the entire block of data to the host at SCSI bus burst transfer rate. The drive's firmware overhead should only occur at a block boundary. Upon completion of the read operation, the drive enters Hold Track State during inactive time.
