Thank you for your answer. 

I think this situation is like as OD devices. Some DVD-RAM/MO/PD
drives are recognized as DA and others are CD. For example, A PD media
is used as a DA on PD drives. The PD media is used as a CD on DVD-RAM
and DVD-ROM drives. It is very confusing. Sometime we want to disable
booting from these devices.

The reason why we want od driver.
