Apparently, dell's already done it.

If dell can do it, apple can do it.

Also interesting:
Now, there are tools out there that allow you to modify the AAM / APM. Unfortunately, AAM is not available on seagate drives, but APM is.
Would someone please test this software and change the APM to 255 and report back? You need to do this in windows (boot).

Here's some more info on AAM from apple discussion forum:
I have a Latitude D830 which included the Seagate ST9120823AS 120GB hard drive. Occasionally, I hear clicking noises from the drive. Usually it is several (maybe 10-25?) successive clicking noises, spread over nearly as many seconds.
Not sure if this will help any one else out there with this problem, but I just noticed that Dell released some updates for other Seagate 7200 rpm drives ... might be of use, so check the model number you have. My drive was the ST9250421ASG so no fix, but this update is supposed to fix ST980412ASG, ST9160412ASG, ST9250410ASG, ST9320423ASG, ST9500420ASG. There was also another release for ST9160418ASG and ST9250464ASG

Works great!
No more marble sounds
"Worked great for me as well.

As far as I can tell, the problem is a direct result of the APM setting on the hard drive, causing an excessive number of spin downs, and therefore an excessive load cycle count. This isn't something that is unique to Seagate drives, or Dell computers either, as I've read reports from a wide range of people with different configurations. Check out this thread, it provides some pretty good information, and it's where I started when I began to try and diagnose the noise.

Here's some more info on AAM from apple discussion forum:
Here's an interesting bit of info I found on another site. Hope it's ok to post it here, because I thought it was very informative. The conversation is about external hard drives, but I would think it applies to internal one's too.
" There are two kinds of noise mostly, the spinning noise that the drive makes when it's running and the "seek" noise as the heads move about. Seek noise is usually in the form of rapid clicks.
Motor noise has come down a LOT in the last few years. Some drives make very little motor noise, some make more. Those with fewer platters inside often make less motor noise as do those that turn more slowly.
Seek noise is often adjustable! Many drives have a feature called "AAM" or "Automatic Acoustic Management". This is nearly always "OFF" by default. Most drives made by Samsung, Hitachi and Western Digital have this feature. It can be turned "ON" and adjusted to various levels in many cases by using Hitachi's Feature Tool, Samsungs Hutil (Samsung drives only) or windows-based tools like HDDScan or HDparm. Turning AAM ON vastly reduces the Seek noise but will slow down access time a little.
For example, a Caviar Black 1TB makes moderately loud Seek noise with AAM OFF but almost none with AAM ON.
Here's my favorites for low noise operation:
WD Green Power. Very little motor noise. These are pretty quiet even with the AAM OFF. Also, they run very cool which is important in an external enclosure.
Samsung. Little Motor noise, AAM is fully adjustable with Hutil. Usually a great silence choice.
WD Caviar Blue Single Platter drives- (160, 320, etc) Little Motor noise, virtually silent with AAM ON. Run cool.
WD Caviar Black with AAM ON. Little Motor noise, slight Seek noise. (Lots of Seek noise with AAM OFF)
Hitachi - Some Motor noise, especially when spinning up. Virtually no Seek noise with AAM ON. Hitachi Feature Tool allows AAM to be fully adjusted.
Drives that make a TON of noise:
Seagate 7200.10, 7200.11. Noticeable Motor noise, plenty of Seek noise, AAM not supported. Also, they run hot.
I'm sure the 10,000rpm Raptors do too!
WD models not supporting AAM or having AAM OFF tend to make plenty of Seek noise. WD doesn't appear to have a AAM tool. HDDScan works OK, sometimes Hitachi Feature Tool will work on WDs too. WD usually only offers AAM "ON" or "OFF" with no fine-tuning like Hitachi and Samsung."
