How can i find out what processes write to a specific disc over time?

In my particular case I got a little homeserver running 24/7 and I included a script in the crontab to shutdown all drives that are not used (no change in /proc/diskstats for 15 minutes).

But my system disc won't come down at all. I'm suspecting logs but it's probably not only logs writing to the filesystem on the system disk and I don't want to go all the way moving the logfiles to something else just to find out the disc still doesn't spin down and there's nothing i can do against it.
