you need the logic board from the said hard drives, thier not just motors with a + and - , they require circuitry to run.

I suppose you meant "arm head motor", not the brushless ones that spin the disk, right ?
You need a "class A" (or bridge) output system, able to flow a certain PWM high frequency signal (around 200KHz is good, higher is better), and the modulation must change the duty cycle ..... or, in alternative, you can use a simple audio power amplifier stage (also low power), but in this case, you have to give a mechanical system for the return force (a spring is enough, for tests, connected in the way that it keep the arm in the middle position when there's no power at the motor)
