You can tell by looking at the direction of the star trails. If they trail in declination, it's polar alignment. If the trail in RA it's periodic error or drive accuracy or lag from poor balance or cable drag.
If you don't know how to tell RA from dec drift, post a photo of the Orion belt area here and someone will be able to help you.
