Sounds like it's already spinning so I don't think the manually spinning method will help.

You seem to be suggesting swapping control boards on the drive. I seriously doubt the control board has failed. It's more likely to be the stepper motor for the heads. If it's the heads, you might have a chance, but I seriously doubt you could pull it off.

I have seen the control board replacement work when the control board itself has crapped itself.

As the others say though, if you are absolutely desperate, you'll be willing to try anything.

Oh and please explain "adger" to a fellow Australian (albeit from Brisbane)...
