Purchased a new HGST hard drive. Using smartctl on OS X the new drive shows 71 hours of power on hours
Does this make sense or is this a sign of a refurbished drive? I can’t imagine why the manufacturer would need it powered on for almost 3 days. I can confirm these values are not minutes or seconds (they have not changed)

You may see a number of power-on hours on a new drive. It is normal for drive manufacturers to test their drives prior to shipping.
For instance, WD RE drives are burn-in tested:
Each drive is put through extended burn-in testing with thermal cycling to ensure reliable operation.
Hitachi is less specific about your particular drive, though they do say:
Engineered for the highest quality, the Ultrastar 7K4000 is put through grueling design tests during development and must pass stringent ongoing reliability testing during manufacturing.
