DESCRIPTION¶
The Write command writes the logical blocks specified by the command to the medium from the data data buffer provided. Will use stdin by default if you don’t provide a file.

-c, --block-count
-z <size>, --data-size=<size>
-y <size>, --metadata-size=<size>
-d <data-file>, --data=<data-file>
-M <metadata-file>, --metadata=<metadata-file>
-p <prinfo>, --prinfo=<prinfo>
