posted from a guy in the Mac discussions: Great news, I no longer have the whining!! I read a message on macintouch from someone saying that Virex was causing some problems with noise on their machine. So i uninstalled Virex 7.5.1 using the uninstall script included in the dmg, deleted all files with the word virex in it, rebooted, and no more whining! I suggeste people give this a try. It worked for me!
