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 al-
lowed 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.
The value in this field specifies the length, in bytes, of each logical block.
