still hearing whistling noise in seagate harddrive. IDE controller included
in Vista might be the issue or a services that is causing this. can't seem to
solve it but all i can do to make it go away is to put computer to sleep for
a second and then wake it up and noise is gone.

Well, no one else is willing to look stupid, so it's my turn.

Whenever I hear intermittent high-pitched noises from one of my machines
it always turns out to be a fan whose bearings are wearing out. I've
started buying replacement fans like beer: by the six-pack.

If the disk is *truly* the source of this noise, my solution would be to
replace it immediately -- under warranty if possible.

Have you tried using a piece of rubber hose or plastic tubing as a
stethoscope? Hold one end to your ear and point the other end around
the computer case until the noise is loudest.

Don:
You might also try booting off a "Live CD" (Ubuntu Linux?) and see (or
"hear") whether the problem persists or not.
A few days after install Vista should stop messing up with the disc (it uses
it very intensively for file indexing).
