Media type

X '00' (default type) must be specified in this field.

Byte 2

Bits 7 and 4 of this field have meaning only in the header transferred to the INIT by the MODE SENSE and MODE SENSE EXTENDED commands. The values specified in these bits are disregarded in the MODE SELECT and MODE SELECT EXTENDED commands. "0" must always be specified by the INIT in the other bit positions.

Block descriptor length

This field indicates the length (block count) of the "Block descriptor" which follows the header (not including the length of the "Page descriptor"). It is possible to define only 1 "Block descriptor" to the HDD, and either X '00' or X '08' must be specified in this field. When X '00' is specified in this field, it indicates that the "Block descriptor" is not included in the parameter list transferred from the INIT and the "Page descriptor" follows immediately after the "Header."
