Hello. I have a SSD and HDD in my laptop, which dual boots(win8 and ubuntu). In Ubuntu, HDD is off, making no sound at all, because it is not accessed by OS. In windows, however, it always is clicking, because every now and then windows decide to write something in the disk, though no applications are open from the disk. What's funny, is that even when I unmount the disk(Disk Management -> Offline), it still is spinning(APM is set for 1 minute). Any ideas?
