No part of this document may be photocopied, reproduced or translated to another language without prior written consent of Sony. The information contained in this document is subject to change without notice. [. . . ] The format of the data returned is different for the six and ten byte commands. See the MODE SELECT (6/10) commands for the mode header format differences. LLBAA: The LLBAA function is not supported. This field is defined for MODE SENSE 10 only. If this field is not set to 0b for a MODE SENSE (10) command, the command terminates with CHECK CONDITION status, the sense key set to ILLEGAL REQUEST, the ASC/ASCQ is set to INVALID FIELD IN CDB. DBD: A Disable Block Descriptors (DBD) bit of ZERO indicates that the target may return ZERO or more block descriptors in the returned MODE SENSE data at the target's discretion. A DBD bit of one specifies that the target shall not return any block descriptors in the returned MODE SENSE data. PC: The Page Control field indicates the type of page parameter values to be returned to the Host as shown below. Table 6-51: Page Control field values Bit 7 0 Bit 6 0 Parameter Values Current Values Description This is the normal default situation where the drive returns to the host its current configuration. Page fields not supported are set to ZERO by the drive. These are any values which a host may alter in a subsequent MODE SELECT command. Any field that the drive allows to be changed is set to one. These are the default values on power-up Not supported by the drive 0 1 Changeable Values 1 1 0 1 Default Values Saved Values The addition page length field of each page returned by the drive indicates the number of bytes supported for that page. Fields not supported by the drive are set to ZERO. Page Code: This allows the Host to select any specific or all pages supported by the drive. The page codes that are supported are: 6-56 SONY AIT-3Ex drive SDX-800V series Ver. 1. 0 MODE SENSE 6. Command Specification Table 6-52: Supported MODE SENSE Page Codes Page Code 00h 02h 0Ah 0Fh 10h 11h 1Ch 31h 32h 33h 3Fh Description Standard Sense Disconnect-Reconnect Control Mode Page Data Compression Control Device Configuration Medium Partitions Parameter Informational Exception Control AIT Device Configuration Append Partition (Not Support) Delete Partition (Not Support) Return All Pages If the Host selects any other values, the drive will terminate the command with a CHECK CONDITION status and an ILLEGAL REQUEST sense key set. Note: If the Page Code is ZERO, the drive will only return the four-byte header and the one eight-byte block descriptor and terminate the command with GOOD status. Allocation Length: The Allocation Length specifies the number of bytes that the HOST has allocated for returned MODE SENSE data. An Allocation Length of ZERO means that the drive will return no MODE SENSE data. This is not considered an error and GOOD status will be returned. Any other value indicates the maximum number of bytes that can be transferred. The drive terminates the DATA IN phase when the Allocation Length bytes have been transferred or when all available MODE SENSE data has been transferred to the initiator, whichever is less. [. . . ] Over Length: The incorrect length condition that exists after executing a read command when the length of the actual block read exceeds the requested transfer length in the command descriptor block. Only the requested amount of data is returned to the host. Partition: The entire usable region of recording and reading paths in a volume or in a portion of a volume. If there is more than one partition, they shall be numbered starting with ZERO (i. e. , beginning of partition ZERO). [. . . ]
