I installed brand new sata HDD (wd black), it is in cage at the bottom of PC case, s.m.a.r.t health check says it is ok, but i hear that weird noise, and i can feel vibration in PC case: https://soundcloud.com/user-653106856/voice-002-sd
I think so, i tried to move it and it is tightly secured, all 4 screws.It is securely mounted? Doesn't shift when you try to move it in the cage?
Are those s.m.a.r.t. attributes ok?If you're not happy with it, wipe it and return it as faulty, as you this is what you suspect. I don't like taking chances with data loss.
