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?
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? (For example SMART polling, etc.)
