What is keeping my hard drive spinning?

hdparm sees to that HD spins down in 20secs of inactivity but some proccess is waking it up every 40secs or so (nothing open but terminal), how can I find out what this is?

iotop -oP only shows me the processes writing (mostly jbd2 (journaling)) but if I can find out what files exactly I could map these to ramdrive maybe...

First thing I would suspect is the logger - stop your syslog program, to check.

Worth checking as well: https://bbs.archlinux.org/viewtopic.php?id=113516

BTW, syslog-ng is of the least hdd intensive loggers IMHO (and as my favourite has replaced other implementations in non-Arch distros).

good try with the logger but it's symlinked to ramfs so there's something else

I've read that thread you linked to but they didn't seem to find any one good solution for it all, kinda open thread still...

Have you tried this:

sysctl vm.block_dump=1

It writes filesystem events into the syslog, so you can see them using dmesg.
