SATA DVD motor control

Hi, how can I control the main motor from SATA pins directly? The point is just simply make it spin.

Like this:

...or if someone can explain what bridges to make in circuit itself.

Can't see what they did but they added a varitable frequency control to the circuit, if you build the same thing yours will probably be different.
