As soon as I launch safari, the HD will begin thrashing continuously for no apparent reason, it will do this for ~10 minutes (constant thrashing) and the noise alone is very annoying. As soon as I close Safari, the thrashing stops and everything is quiet again. Then I relaunch Safari and it starts thrashing again. It's driving me CRAZY! No other browser behaves this way. Does anyone else have similar problems with Safari and is there any way to "shut it up"?
