2.47 Read CD-DA MSF (D9h)

IMPORTANT: This command applies only to models DRM-602X, DRM-624X, and the DR-U
Series drives.
Operation Code is (D9h).
Starting M, S, F Fields indicates the absolute MSF address where the operation begins.
Ending M, S, F Fields indicates the absolute MSF address where the operation ends. If the
ending address is smaller than the starting address, check condition will be returned. The sense
key is set to Illegal Request (05h), the additional sense code is set to Invalid field in CDB (24h).
Sub Code Field - for details, refer to the READ CD-DA command.
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.
