SCSI Commands

WRITE FILEMARKS Command (10h) (continued)

The WRITE FILEMARKS command may be used to force the tape drive to write any buffered WRITE data to the tape medium. If the tape drive is in buffered mode, and WRITE FILEMARKS is received, the requested filemarks are appended to the data and the WRITE buffer contents are flushed to tape medium. A value of 0 in the Number of Filemarks field indicates that no filemarks are to be written to the tape medium, but still flushes any WRITE data to the tape medium.

If End of Tape (EOT) is detected while writing filemarks, the tape drive finishes writing any buffered data and terminates with CHECK CONDITION status. Within the Sense data, the End of Medium (EOM) bit is set, the Sense Key field is set to NO SENSE and the Additional Sense Code and Additional Sense Code Qualifier fields are set to EOM/P DETECTED. The tape drive attempts to complete any subsequent WRITE FILEMARKS, returning a CHECK CONDITION status in each case. If the tape drive encounters the physical EOM when attempting a WRITE FILEMARKS, it returns CHECK CONDITION status.
