Noisy External HD

Magfan: What software update did you use?

The rubber washer idea is worth a try. It does get quieter after about 20 minutes by itself but still not enough to satisfy me. There is no fan so it must be the HD's themselves in which case rubber mounts could be a solution. Thanks for the idea.

I appreciate the suggestions. Since I just spent almost $200 on two new WD (Caviar Black) HDs for the Cavalry unit I want to figure out a solution other than buying new ones again. It may come to that nonetheless!

Almarg: Thank you for that input - I was not aware of any of that. The noise is not a fluctuating seek noise but rather a steady loud whirring noise that diminishes with time (maybe 15-20 minutes). It reminds me of an automobile starting in cold weather - it takes a few moments for it to settle out if you get my analogy. I will look into your other suggestions nonetheless.
