+DESCRIPTION
+-----------
+The Write Zeroes command is used to set a range of logical blocks to 0.
+
+OPTIONS
+-------
+--start-block=<slba>::
+-s <slba>::
+ Start block.
+
+--block-count=<nlb>::
+-c <nlb>::
+ Number of logical blocks to write zeroes.
+
+--prinfo=<prinfo>::
+-p <prinfo>::
+ Protection Information field definition.
++
+[]
+|=================
+|Bit|Description
+|3|PRACT: Protection Information Action. When set to 1, PI is stripped/inserted
+on read/write when the block format's metadata size is 8. When set to 0,
+metadata is passes.
+|2:0|PRCHK: Protection Information Check:
+|2|Set to 1 enables checking the guard tag
+|1|Set to 1 enables checking the application tag
+|0|Set to 1 enables checking the reference tag
+|=================
+
+--ref-tag=<reftag>::
+-r <reftag>::
+ Optional reftag when used with protection information.
+
+--app-tag-mask=<appmask>::
+-m <appmask>::
+ Optional application tag mask when used with protection information.
+
+--app-tag=<apptag>::
+-a <apptag>::
+ Optional application tag when used with protection information.
+
+--limited-retry::
+-l::
+ Sets the limited retry flag.
+
+--deac::
+-d::
+ Sets the DEAC bit, requesting controller deallocate the logical blocks.
+
+--force-unit-access::
+-f::
+ Set the force-unit access flag.
+
+--namespace-id=<nsid>::
+-n <nsid>::
+ Namespace ID use in the command.
