Since installing Vista Ultimate i have been experiencing annoying and
disturbing noises. I have found that my hard drive is regularily spinning up,
down and up at random intervals, i have seen no distinct pattern at all. But
i can distincly hear the drive spining, it also causes freezes on my computer.

The noises i recognise from XP whenever i shut my computer down (and only
when) There's like a click, a pop and some spinning. Other times i hear a
high pitched spinning noise getting higher and higher. I have also heard
another friend mention a similar noise comming from his computer.

The only thing i can possibly think of is Drive Ready (for hybrid drives) or
Drive Boost (for flash storage) causing this issue due to some
incompatibility?

Any help at all is greatly appreciated!
