    Ok,

    I am getting HD noise like every 20 seconds.. Even with no activity.

    Per the suggestions of another user, I typed this in terminal:

    iostat -w 1 disk0

    and the sound seems to coincide with the output whenever the first column has a value other than 0.

    So it seems there is activity, it's just not user initiated..

    is this some kind of energy saving feature that apple is doing or is it a logging application?..

    Is anyone else having the same issues? Even if you're not, could you run the program and check for 1 or 2 minutes (without any other apps open or doing anything) to see if you also get a value other than 0 in the first column every so often and an associated sound?

    Thank you,
    Wesley

    hmm first ..what is build around that harddrive
    other thing only because you dont have a obvious program running, does not mean the harddrive has to stand still , there are a couple things which will run in the backround and are unavoidable if youwant to see something on the screen , think about it , you dont stop breathing only because you are doing noting obvious:D
    but to stay serious it would be helpful to know what you got there
    as by now my guess is as good as yours
    ok i assume you got a mac there with harddrive inside ,but it could be a external too

    when i first got my base 27" the noise drove me up the wall so i took it back thinking it wasnt right, i then got my second one and that was the same i did try and put up with it but enough was enough so then got a credit note and decided to try out the quad core when it appears in the retail stores... nothings to say thats going to be any quieter but i will just have to live with it i suppose
