The WRITE AND VERIFY command receives and writes data for the specified
number of blocks from the specified logical block address.

Logical Block Address specifies the head logical block address used to start
writing.

Transfer Length specifies the number of blocks to be transferred and written.

The ByteChk bit indicates data compare execution. However, since the ByteChk
is not supported, it must be set to 0. If a value 1 is specified, the command ends
with Check Condition.

When Transfer Length is 0, the command does not carry out data transfer. It
simply ends normally without writing any data.
