01b When set to 00b, the Stop On Consecutive Filemarks (SOCF) field indicates the
device pre-read data from the medium in Buffered Mode to the limits of the buffer
capacity without regard for filemarks. This implies the device can differentiate
between data blocks and filemarks in the buffer. Values 01b, 10b, and 11b specify
the device terminates the pre-read operation if 1, 2, or 3 consecutive filemarks are
detected, respectively.
The SOCF field is reported as changeable on a MODE SENSE command, and the
default value is 01b.
0 When set to zero, the Automatic Velocity Control (AVC) bit indicates that the device
speed chosen will be the device's internally selected speed.
The AVC bit is reported as not changeable on a MODE SENSE command, and the
default value is zero.
1 When set to one, the Block Identifiers Supported (BIS) bit indicates that the format
on the medium has recorded information about the logical block ID relative to a par-
tition.
The BIS bit is reported as not changeable on a MODE SENSE command, and the
default value is one.
1 When set to one, the Data Buffer Recovery (DBR) bit indicates that the target sup-
ports data buffer recovery using the RECOVER BUFFERED DATA command.
The DBR bit is reported as not changeable on a MODE SENSE command, and the
default value is one.
00h The Gap Size field determines the size of the interblock gap when writing data.
A value of 00h specifies the device's defined gap size.
This field is reported as not changeable on a MODE SENSE command, and the
default value is zero.
1 When set to one, the Synchronize at Early Warning (SEW) bit indicates the target
causes any buffered write data and filemarks to be transferred to the medium when
EOM early-warning is encountered.
This field is reported as not changeable on a MODE SENSE command, and the
default value is one.
0 When set to zero, the Enable EOD Generation (EEG) bit indicates that EOD genera-
tion is disabled in the logical unit.
The EEG bit is reported as not changeable on a MODE SENSE command, and the
default value is zero.
The End-of-Data (EOD) Defined field indicates which format type the logical unit
uses to detect and generate the EOD area.
A value of 000b in this field indicates the logical unit will use its own default EOD
definition.
The EOD Defined field is reported as not changeable on a MODE SENSE com-
mand, and the default value is zero.
