I actually think I continue to have issues with this HDD clicking.
I took another approach to this issue and had a chat with a Fujitsu (my HDD manufacturer) rep. This is part 3 of my most recent blog about all this Hard drive clicking. Here is how it went:

UPDATE 3: Another new day, today being Tuesday, December 9, and I think my Macbook's hard drive is intermittently clicking again! Noooooooo! I give up. Apple, Fujitsu, fix this for me. The HDD is clicking but maybe not as often, sure, that's right, it is not clicking as often. Anyone who tries the band-aid fix above, please e-mail me, and let me know if you had any amount of success in ridding your notebook of the hard drive clicking.
While I do think the "fix" outlined in UPDATE 2 had some minimal effect on reducing the overall number of "ping-pong-ball-bounce-esque" clicks emanating from my Macbook I still decided to take this up with Fujitsu, the maker of the 250GB HDD in my Macbook. Dialed up some live chat with a Fujitsu rep., here is how it went (spoiler alert: not so great):
Please wait while we find an agent to assist you...

Giancarlo: Welcome to our FCPA live chat service. How may I assist you?
Doug A: This HDD in question, combined with Apple's Mac os 10.5.5 is a MAD CLICKING thing...........
Doug A: APM? / firmware tool is needed bad
Doug A: hitachi makes a tool to help correct this, why not fujitsu?
Giancarlo: What is the part number of the drive that starts with a CA0
Doug A: huh?
Doug A: Capacity: 232.89 GB
Model: FUJITSU MHY2250BH
Revision: 0081000D
Serial Number: K43XXXXXXXXX
Native Command Queuing: Yes
Queue Depth: 32
Removable Media: No

Giancarlo: Where did you get the drive?
Doug A: OEM, earily 2008 macbook, Apple
Giancarlo: Had a feeling just looking at the firmware revision.
Giancarlo: Any firmware requests would need to go through Apple
Doug A: so you have nothing for me?
Giancarlo: I'm sorry I do not. Apple (and other companies) take our drives and flash their firmware on the drive, thus taking ownership of that aspect
Doug A: Thanks. It's official folks, Fujitsu is passing the buck and not taking ownership on this issue (for my blog).
Giancarlo has left the session.

Doug A: So, this has nothing to do with an over-aggressive Power Management System that is built into the drive itself?
Doug A: Are you still here?
Giancarlo: I'm sorry I have nothing regarding this
Doug A: How about a manager?
Doug A: i.e. your supervisor. Are you still with me?
Giancarlo: I'm looking for one that is available
Giancarlo: I'm sorry I'm not getting anyone available at the moment but I can do the next thing and send this over to engineering to see if they can go through some channels
Doug A: my email is xxxx, I would really like some answers to this. Apple does not want to take ownership on this situation that seems to be some sort of conflict between your HDD power management, Apples sudden Motion Sensor, and something? Linux suffers from this same problem, so HDD manufacturers need to take a bit of ownership on this widespread problem. There are forum threads all over the web about the HDD clicks!
Giancarlo: Okay I'll pass this on to engineering and see what they have to day
Giancarlo: I mean say
Giancarlo: Sound like a plan?
Doug A: I will be waiting for an answer. thank you. If I hear nothing, I'll be back to inquire some more, OK?
Giancarlo: Very good
Doug A: document and save this session for further reference, OK
Giancarlo: It already is
Your session has ended. You may now close this window.
OK, Apple, it looks like the ball is in your court...
