Yes, it only comes when system / hdd powers down, comes completely
from HDD, highly possible from motor. But i've been using that disk
for more than 3 years and power-on hours is about 9 months(Smart
value). Usually it comes, sometimes it doesn't(When there's no
excessive read/write operation)

I also check integrity of drive with Seatools passed OK.

So what would be your final conclusion words?
