EEG: Enable EOD Generation—When set to 1, this bit indicates that the logical unit 
shall generate the appropriate EOD area, as determined by the EOD Defined field. A 
value of 0 indicates that EOD generation is disabled. 1 is the value supported. This 
field is non-changeable. 
SEW: Synchronize at Early Warning (SEW)—When set to 1, and Logical Early 
Warning is encountered during a WRITE operation, the tape drive will truncate the 
current command, write any buffered data to the tape, and return a Check Condition 
with EOM set in the Sense Data. 1 is the value supported. This field is non-
changeable. 
NOTE:  When Logical Early Warning is detected, the drive will not interrupt the 
current DMA, which will be 64Kbytes or less. Notification will be given when 
the current command completes, or if the data left to be written is to large 
notification will be given on the maximum burst DMA boundary. 
Buffer Size at Early Warning is always 0, indicating the buffer size is device 
specific.

Maximum Additional Partitions field indicates the maximum umber of additional 
partitions supported by the drive. The value of this field is returned during a MODE 
SENSE command. It will always be set to 0, indicating the drive supports one data 
partition consistent with QIC-157D, table 5-44. This parameter is not changeable. 
Additional Partitions Defined field specifies the number of additional partitions to 
be defined for a volume when SCP or IDP is set to 1. This field must be set to 0, and 
is not changeable. 
FDP: Fixed Data Partition bit may be changed by a MODE SELECT command only 
when the drive is positioned to BOT. When set to 0, the drive considers the entire 
media as a single partition. When FDP is set to 1 the drive is in dual partition mode. 
FDP does not cause the selected partition to change. CAP in page 10h is used for 
that function. The FDP bit default value is 1 and it is not changeable in STT3401A 
mode. 
Select Data Partition (SDP), Initiator-Defined Partitions (IDP), and Partitions 
Size Unit of Measure (PSUM)
 fields shall be set to 0, indicating that the STT3401A 
drive assigns partitions base on its pre-defined definition of the data and directory 
partitions. These values are not changeable by the Host.
