HDAPS parking/un-parking Question (solved)

So I've recently configured a new Thinkpad T410 with tp_smapi supplied HDAPS, and noticed frequent parking in /var/log/everything.log.  I was just curious if others have experienced the same.  Watching the log live with multitail I can see that relatively slight nudges to the laptop cause the HDD head to park.  Here's a sample:

Jun 25 18:34:52 slappy hdapsd[5730]: parking
Jun 25 18:37:38 slappy hdapsd[5730]: parking
Jun 25 18:37:39 slappy hdapsd[5730]: un-parking
Jun 25 18:42:49 slappy hdapsd[5730]: parking
Jun 25 18:42:50 slappy hdapsd[5730]: un-parking
Jun 25 18:47:10 slappy hdapsd[5730]: parking
Jun 25 18:47:11 slappy hdapsd[5730]: un-parking
Jun 25 18:47:50 slappy hdapsd[5730]: parking
Jun 25 18:47:51 slappy hdapsd[5730]: un-parking
Jun 25 18:49:26 slappy hdapsd[5730]: parking
Jun 25 18:49:27 slappy hdapsd[5730]: un-parking

Log snip above is after I changed the initial sensitivity from 15 to 20, while typing this out and sitting on the couch.  I can't say I know much about the technology, so I'm unsure if that's so good for the drive to be parking/un-parked with such frequency.

Even if someone running tp_smapi HDAPS could just check their logs for similar occurrences, it would be most appreciated

Hi, the first time I read this post, I went to my logs and nothing appears about hdapsd, this is the reason because I don't answered your question.
But today, after read your response, I go again to my logs and find the same symptom: a lot of entry in my logs about parking/unparking

Something appear changed in the rules about hdaps and syslog-ng, before when I move my thinkpad nothing appear in my logs, now when I shake my thinkpad I can see a lot of entry in my logs

I think is normal

Well, it's been logging since I installed it.  My question is really about the frequency, and if it has any bearing on HDD life.

I talked with someone on the hdaps IRC channel and they suggested that the sensitivity was too low (default 15).  I upped it to 30 and that seems much better.
