Help! Macbook black!

I removed the HDD inside my Macbook black and was shocked to find that there's only 1 " ribbon cable" inside the HDD slot, instead of 2 as shown in

1) what's the function of this " ribbon cable"?
2) what will happen if there's only 1 instead of 2? will it affect my macbook? will it cause it to be non-functional ?

thanks.

That one cable is the SATA connector to the logic board. That is all that is needed. That one connector has the needed two separate connections for the hard drive.
