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

The ByteChk bit controls data compare processing. However, since the ODD does

Check Condition. If Transfer Length is 0, the command transfers no data. It
simply ends normally without writing any data.
