OPTIONS -s <slba>, --start-block=<slba> Start block. -c <nlb>, --block-count=<nlb> Number of logical blocks to write zeroes. -p <prinfo>, --prinfo=<prinfo> Protection Information field definition. +-----+----------------------------+ | Bit | Description | +-----+----------------------------+ | 3 | PRACT: Protection | | | Information Action.

Only one output format can be used at a time. -v, --verbose Increase the information detail in the output. -t <timeout>, --timeout=<timeout> Override default timeout value. In milliseconds.
