154 Commands
Zero or more blocks of data are transferred from the host to tape starting at the
current logical position.
It is recommended that the Buffered Mode field of the
is set to either 1 or 2 so that Immediate reporting is enabled; upon a write
command the drive will report
transferred to the data buffer (but not necessarily to tape).
Data held in the buffer is flushed to tape in the following circumstances:
A SCSI command is received that forces a flush:
ERASE
LOAD
MODE SELECT READ
SPACE
VERIFY
Buffered mode is not enabled. If buffered mode has not been set to 1 or 2,
the buffer is flushed before the command completes.
The write delay time is exceeded. This is defined by the Write Delay field of
the Device Configuration Mode Select page. If the drive is idle for longer
than this period (no operations that access the tape have been performed),
any data in the buffer is flushed to tape.
