Controlling a Hard Drive

Projects General Guidance
1

So I have an old hard drive that I opened up and I would like to be able to control it. I have an arduino so I'm guessing that's what I would be using, and I'm looking for the cheapest and simplest way to make the disks spin. All I need to do is make the motor spin at a high speed, and everything I have found involves a higher level of control than I need, and assumes previous capability to run BLDC's. I'm really new to this, and I'm just looking for some information to get the motor spinning.

Thanks in Advance.

Note: I opened up an old computer and plugged it into that and discovered it will spin with just the four-prong power connector plugged in, so I'm thinking this might be the route of least resistance... just a thought.

If that's all you want, and you don't have any other requirements (like leaving the drive in a usable state afterwards, or being able to do anything at all other than spin it) then you just need to apply the appropriate voltage to the drive motor.
