Does this actually have to do with Ubuntu accessing the disk for *read/write* or may this be related to some other kind of polling? (Temperature, etc.)
I ran iotop on my laptop in AC mode with hdparm -B 199. While iotop showed no disk activity at all, frequent load/unload cycles occured. I also noticed that running smartctl -a when the heads are parked the heads are unparked immediately. Can I somehow monitor hard disk activity besides read/write activity?
