Im looking for some small script or application which could log the time when a non-system disk wakes up.

I cannot identify which application or script wakes up my non-system drive (which has to be asleep until I work with it). I have already set the noatime flag, tried to use powertop and iotop to determine which application could prevent it from going to sleep - but with no result.

So my plan is to set this drive asleep (hdparm -Y) and see at what time it gets regularly woken up.

Thanks for any advice.
