An operating system doesn't tell a hard drive how much noise to make.
Rather, in Vista the drive is probably quite active due to the initial
indexing and monitoring. This increased activity is causing the drive to
work harder than it has with XP, and the increased activity is moving the
heads around more than it is used to. This chattering should normally settle
after a few days, but if it's more of a high pitched whine then the drive
could be in the beginning stages of failure.
