Buy any brushless controler for RC models and use it to drive HDD motor
it should work fine

Hdd motor is BLDC, not stepper. if you drive it as stepper it will owerheat

Its a kind of stepper motor. http://www.cs.uiowa.edu/~jones/step/ is the web bible on steppers.

The way a brushless motor works is by switching the magnets and the coils. It also uses 3 rotors, so it would require 3 different connections. As far as i know, you would need a brushless speed controller. This at least goes for the motors we would be using for robotics.
