Agree with Fredrik; at a previous job we had a large group of
extremely noisy U30's and U60's. After playing around with the
one or two that were *not* noisy, it was clear that the culprit
in our case was a run of very, very noisy 9GB Seagate drives.
Amazingly noisy. Sun declined to replace them under warranty
solely for noise complaints, and refused in general to acknowledge
there was a noise problem. Several of these drives suffered
mysterious sudden severe failures. :-) At the time, you had
about a 50% chance of the replacement drive being quiet.
Other users coped by erecting small walls of open-cell packing
foam in front of the machines (good high-frequency attenuation).
