I got new hitachi travelstar and by new I mean it had only 2 hours power on. The G-sense error rate was 200 thousand once and now it's 66 thousand but sometimes it drops to 0, I'm using DriveDX to diagnose. Otherwise all tests are 100% although randomly it makes a sound not sure if it's meant to do that maybe it's switching platters or something?

I've been waiting for test to conclude. Here are two reports you see how big the difference is, the laptop never left my desk so 0 should be the number.
