Does any one have any ideas how to track down what's waking my hard disk up every few seconds? The problem is that the Linux PC sometimes spends hours not being used and I'd like the HDD to spin down after (say) 15 minutes of inactivity. I've set the BIOS power-saving HDD spin-down and this works well enough when booted to DOS, but in Linux it just won't sleep. If I force it to sleep using 'hdparm -y /dev/hda1', it spins down and promptly starts up again after a few seconds.
I did see an interesting progam in Debian called noflushd which is supposed to spin down disks and prevent them being written to until something needs to read. I haven't tried it out yet.
