My laptop can be completely idle with no applications open and then all of a sudden the HDD will start making a noise but the HDD activity led does not come one. The noise goes on for about 30 seconds and then dissapears, about a minute later the same noise will appear again but this time for a shorter duration and by the time the screen blanks the noise no longer appears. The noise does not appear if I'm booted into a plain text console/terminal, only when loading X/Ob.
atop & collectl report no disk activity. The drive is also not load cycling as laptop-mode-tools are installed and the counter for load cycling does not increase.
So can anyone tell me what the cause of this noise is?
