SONY AIT-3 drive SDX-700 series Ver.2.1
The DBR and BIS bit are only valid on a MODE SENSE command where they are used to report drive capabilities.
These bits are ignored by the drive on a MODE SELECT command. The drive will not return a CHECK CONDITION.
RSmk
: The Report Set Mark bit, when set to one, indicates that Set Marks will be reported to the drive. When ZERO,
Set Marks are NOT reported. The default is one, Set Marks reported.
AVC
: Automatic Velocity Control function is not supported by the drive and if this bit is set a CHECK CONDITION
status is returned with an ILLEGAL REQUEST sense key.
SOCF
: Stop on Consecutive File-marks function is not supported by the drive and if this bit is set a CHECK
CONDITION status is returned with an ILLEGAL REQUEST sense key.
RBO
: This field is not supported. If this bit is set a CHECK CONDITION status is returned with an ILLEGAL
REQUEST sense key.
REW
: The Report Early-Warning End-of –Media bit is set to ZERO indicates the drive will not report the
early-warning condition on reads but will report early-warning on writes at a distance of 2,500 mm before the
physical End-Of –Partition. The REW bit is changeable. A value of ONE indicates that the drive will report the
early-warning condition on writes and reads.
Gap Size
: This field is not used by the SDX-700C and shall be set to ZERO otherwise a CHECK CONDITION with
an ILLEGAL REQUEST sense key will be returned.
EOD Defined
: This field shall always be set to ZERO so that the drive will use its default EOD definition to detect and
generate EOD. Any other value will cause the drive to return a CHECK CONDITION status with an ILLEGAL
REQUEST sense key set.
EEG
: The Enable EOD Generation bit shall always be set to indicate that drive will generate an EOD. The drive
generates an EOD mark prior to any change of direction, if that change follows a write-type operation. This bit is only
valid on the MODE SENSE command where it is used to report drive capabilities. This bit is ignored by the drive on
a MODE SELECT command. The drive will not return a CHECK CONDITION.
SEW
: The Synchronize at Early-Warning bit is set to ONE indicates buffered write data, File-marks and Set-marks at
or after Early-Warning End-of-Media will be written to the Medium. The SEW bit changeable. A value of ZERO
indicates that the target will retain any unwritten buffered data, File-marks, or Set-marks in the buffer when logical
Early-Warning is encountered. The default is 1.
Buffer Size at Early Warning
: This field is not supported by the drive and if set a CHECK CONDITION status is
returned with an ILLEGAL REQUEST sense key set.
Select Data Compression Algorithm
: The SDX-700C supports the Data Compression Page and that page should
be used instead of this field to control Data Compression. This field is not supported by the drive and if set a CHECK
CONDITION status is returned with an ILLEGAL REQUEST sense key set.
