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. The 

Allocation Length must fall on header or block descriptor boundaries. If the Allocation Length does not fall on these 

boundaries then the drive returns CHECK CONDITION status with the ILLEGAL REQUEST sense key set, unless 

the value is greater than that required for the specified page. 

If the Page Code is ZERO, the Host requires MODE SENSE to only return the four-byte header the one eight-byte 

block descriptor, therefore the Allocation Length must be set to 0Ch. The value of the Page Control Field is then not 
checked by the drive and may be set to any value.  

If the Allocation Length is non ZERO, it must be set to 4 or more. If the Allocation length is non ZERO and less than 

4, the drive will return CHECK CONDITION status, and ILLEGAL REQUEST sense key. 

The MODE SENSE data contains a four-byte header, followed by one eight-byte block descriptor, followed by ZERO 

or more variable length pages, depending on the Page Code and the Allocation Length.

Mode Data Length: The mode data length specifies the length in bytes of the following mode sense data that is 

available to be transferred during the DATA IN phase. The mode data length does not include itself but does include 

the total length of all requested MODE SENSE pages.
