The WRITE AND VERIFY command receives the specified number of blocks of
data and writes it beginning at the specified logical block address. Logical Block
Address specifies the logical block address at which the command should start
writing data. Transfer Length specifies the number of blocks of data to be
transferred and written.

The ByteChk bit controls data compare processing. However, since the ODD does
not support ByteChk, it must be set to 0. If 1 is specified, the command ends with
Check Condition. If Transfer Length is 0, the command transfers no data. It
simply ends normally without writing any data.
