I use phone to record so please ignore the constant background noise. it's the clicking sound every 3 seconds which I have concern with. the click sound is only noticeable when the room is quite.
hardware: poweredge T110, 4GB memory, 2 wd 8TB red disk (purchaed form bestbuy 2 months ago, removed from 8TB WD easystore USB 3.0 External Hard Drive ), raid 0
when I got it, I use crystaldiskinfo, WD drive utility to scan, and it looks good.
Is that noise typical? I didn't have file transfer, or music/video stream at this moment. and I checked system log, there is registered event every minute, but the clicking noising is about every 3 seconds.
