BigD,
I am no electrician, but will tell you what my electrician just did at my place.
I have a 100A 220 subpanel in the garage that I put in, buried EMT and then I pounded a grounding rod for the sub panel, thinking more is better, in addition to the house grounding rod.
Mr. Sparky noticed it , and was very kind to not rip me down at my knees for adding the additional rod at the garage panel .:banghead3 We yanked it out, and disconnected the grounding wire in the panel as well.
I would check with the electrician who wired yours, as to what to do.
