Transfer Length specifies the number of blocks to be transferred and written.
When Transfer Length is 0, the command does not carry out data transfer. It simply ends normally
without writing any data.
It is recommended that the WRITE (10) command is used because there is ATAPI device which
does not support the WRITE (12) command.

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.
It is the same as the WRITE (10) and WRITE (12) commands.
