Data Field
Description
Mode Data Length
Length of the returned data
Medium Type
Always zero (0)
Device-Specific
Parameter
Bit 7 - This bit is set if the drive is write protected 
Bit 4 - This bit is always set to indicate that the drive supports cache memory.
Block Descriptor
Zero (0) if Block Descriptor (DBD) in MODE SENSE Command Descriptor Length sector is 0. 
If DBD is 1, then the Block Descriptor Length is eight (8).
Number of Blocks 
The value in this field specifies the number of logical blocks on the unit that are affected by the 
current MODE SELECT command. When this field = 0, the MODE SELECT parameters are put 
into effect for all logical blocks on the unit. The maximum value allowed is the total number of 
initiator-addressable logical blocks for the value specified in the Block Length field. A value that 
is less than the maximum value will decrease the number of initiator-accessible logical blocks to 
the amount specified.
Block Length 
The value in this field specifies the length, in bytes, of each block.
