Normally, the bridge chip will not release the RESET- line on the Parallel ATA bus until after the OOB handshake is completed on the SATA bus. The drive will not spin up while RESET- is held low. So the drive will not spin up until communication is established between the Host Adapter and the Sata Bridge chip.
