My New Brand WD MyBook Live Duo HDD is working loudly. When I copy files from my HDD to my computer or vice versa, sometimes hdd is making some kind of knocking sound(but not exactly head crash sound) and then it come back to normal and then it starts again…
I checked my files(CRC checks) and there is no problem with them, all are functioning. WD smartware says hdds are fine. HDDs are running at RAID0 mode.
Oh by the way, when the sounds starts once I copy some files, copy data rate reduce a bit(from 55-60 Mb to 30-35Mb).
You think it’s normal for this WD model or is there a problem with HDD heads?
