Something isn't adding up here. I've been running 4x of these HGST SAS 4TB drives 24x7 since I built my 1st server in early 2018. They were used when I bought them (2014 build date). Why don't I see 70,000+ hours? FYI, I ran SMART short test yesterday...which shows at 1487 hours. Today it is showing 1502 hours. I certainly didn't do anything to zero out the hours and even if the previous seller did, it should show at least 40k hours
