"very accurate"? so a "master" hard drive issues commands to a "slave" drive?

Yes, exactly. Take IDE drives for example. To use two drives with a single cable, one is set to be the master, the other to be the slave. From that point onwards, the slave cannot write to the bus until the master gives permission.
I was referring to newer ATA drives. Nevertheless, in your example no orders (or ownership!) are implied.
