I've noticed since the last update that the hard drive in my HR21-700 seems very loud. It sounds like an old PC hard drive churning away when trying to perform a task. I don't know how else to explain this in any better terms, so this is the best I can do. I have only noticed this in the past few weeks, and have not made any changes to my setup or system, other than to get the new software. Anyone else experiencing this or know what I'm talking about? Any help would be appreciated. Thanks.
