The default (factory programmed) value is 0.
The Drive only supports a single fixed Write Buffer Full
Ratio so this field must be set to zero. This field is
not changeable.
The Drive only supports a single fixed Read Buffer Empty
Ratio so this field must be set to zero. This field is
not changeable.
The Write Delay Time field is ignored by the Drive.
The Data Buffer Recover (DBR) bit must be set to 0, it
is not changeable

The Block Identifiers Supported (BIS) bit must be set to
1, it is not
Identifiers).
The Report Setmarks (RSMK) bit must be set to 1, it is
not changeable (the Drive reports setmarks).
If the Automatic Velocity Control (AVC) bit is set to
one, the Drive will select the speed which, based on the
data transfer rate, will optimize streaming activity and
minimize medium repositioning (only if more than one
speed is available for the active tape format). If the
AVC bit is zero, the speed specified in the header list
is chosen.
Legal values are 0 and 1.
The default (factory programmed) value is 1.
Note that the AVC bit has priority over the Tape Speed
field (see section 14.3.1.
that when AVC is active the drive ignores the value of
the Tape Speed field.
The Stop On Consecutive Filemarks (SOCF) field must be
set to 0 for
changeable.
The Recover Buffer Order (RBO) bit must be set to 0, it
is not changeable (the Drive has no RECOVER BUFFERED
DATA command).
The Report Early Warning (REW) bit must be set to 0, it
is not changeable (the Drive does not report Logical
Early Warning (LEW) when reading).
The Gap Size field
changeable (the Drive will determine the size of the
inter-block gap when writing data).
The EOD Defined field must be set to 00h, it is not
changeable (the
definition to detect and generate EOD).
The Enable EOD Generation bit must be set to 1, it is
not changeable (the Drive will generate an appropriate
EOD area).
The Synchronize at Early Warning (SEW) bit must be set
to 1, it is not changeable (the Drive makes sure that
any write data, filemarks or setmarks to be transferred
to the medium
encountered).
The Software Write Protect (SWP) must be set to 0, it is
not changeable
