[8] The Interleave field is the interleave value sent to the disc drive during the last Format Unit command.
Note.
This field is valid only for Mode Sense commands. The disc drive ignores this field during Mode
Select commands.
[9] The Track Skew Factor field indicates the average number of physical sectors between the last logical
block on one track and the first logical block on the next sequential track of the same cylinder. A value of
zero indicates no skew.
Note.
This value is not changeable by an initiator.
[10] The Cylinder Skew Factor field indicates the average number of physical sectors between the last logical
block of one cylinder and the first logical block of the next cylinder. A value of zero indicates no skew.
Cylinder skew will be utilized by a disc drive but is not changeable by an initiator.
[11] The Drive Type field bits are defined as follows:
The Hard Sectoring (HSEC) bit (bit 6) set to one indicates the disc drive shall use hard sector formatting.
The soft sectoring (SSEC) bit (bit 7) when set to one indicates the drive uses soft sectoring.
Bits 0-5, and 7 are not implemented by the disc drive and are always zero. All bits (0-7) are not change-
able.
[12] See drive Product Manual Mode Sense Data section for changeable values.
