It's a valid question, why does once parked head come back to be parked
again. I do not know what on the OS wakes it up, but the behavior has been
same across OSes (NetBSD, Linux). It could also be a flaw with the drive
firmware.

Even assuming there was some activity form OS/application side, parking it
again within a minute is still annoying in my view.
