Parameter Data Formats
4 - 32 C141-E167
If this parameter is issued, only the format parameter of the zone specified by the MODE SENSE
command can be referred to without changing the number of accessible blocks.
Also, if a MODE SENSE command with a SP = "1" that includes a notch page is issued, the current
value is reported for this page and the zone value which is the object is reported if Page 3 is notched,
then the command is terminated normally. However, in the case of the FORMAT CORRUPTED
state, caution is necessary because the value following changing of the Format parameter is reported.
The contents of each parameter are explained below.
• ND (Notch Drive)
"0" : Since the device is not in the notched state, "0" is reported for LPN, active notch, starting
boundary and ending boundary.
"1" : Since the device is in the notched state, the starting boundary and ending boundary for the
zone number (+1) shown in the active notch is set in the format specified in the LPN Bit.
• LPN (Logical or Physical Notch)
"0" : This shows that the boundary address is based on the physical address format. At that
time, the higher order 3 bytes show the logical cylinder number and the lowest order byte
shows the logical head number.
"1" : This shows that the boundary address is based on the 4-byte logical block address format.
This bit is a bit which must be set during MODE SELECT.
• Maximum Number of Notches
This indicates the number of device zones. 18 (X'12') zones are set for all drives.
• Active Notch
This specifies the zone number 1 to 18 of a notching zone. If "0" is specified, the page and
parameter changed by the notch page, and the notch page itself, are changed to the initial value.
If a value which exceeds the maximum number of notches has been specified, the test ends by
"CHECK CONDITION" status (ILLEGAL REQUEST [=5]/Invalid parameter in List [=26-00]).
This field is a field which must be set during MODE SELECT.
