Mountain Lion runs very clunky but Windows 7 runs quick

    Here is what I have:

    27 inch Mid-2011 iMac
    3.1GHz i5
    12GB 1333Mhz DDR3
    AMD Radeon HD 6970M 1024MB
    OSX 10.8.2

    1 TB HDD with 250GB on Bootcamp running Windows 7. I have about 150GB free on the OSX side if that makes a difference.


    For some reason OSX seems incredibly clunky compared to Windows. I have one of those HDDs that sounds like a stomach churning and I almost always hear it running in OSX but not much in Windows 7. Granted, I'm in OSX far more than I am Windows.

    Would a reinstall of OSX help anything? I would then lose my Windows bootcamp unless I got something like WinClone, right?

    EDIT: Sorry, meant Mountain Lion

    You can run Disk Utility's Verify Disk with the Macintosh HD selected to check for errors in the file structure. If you need to repair though, you will need to boot to OS X Recovery, then run the Repair Disk. It's not clear from your symptoms whether reinstalling OS X may fix whatever if going on, but doing so should not affect Boot Camp, unless you decide to repartition the drive.

    I just ran Onyx the other day and it seemed to verify just fine.
