This command requests that the device server write the single block of data transferred by the application
client to the medium multiple times to consecutive multiple logical blocks.
A "Logical Block data (LBdata)" bit of zero and a "Physical Block data (PBdata)" bit of zero indicates
that the single block of data transferred by the application client shall be used without modification. A
"LBdata" bit of one requests that the device server replace the first four bytes of the data to be written to
the current logical block with the logical block address of the block currently being written.
A "PBdata" bit of one requests that the device server replace the first eight bytes of the data to be written
to the current physical sector with the physical address of the sector currently being written using the
physical sector format.
