    The MacBook has a built in Sudden Motion Sensor. The Western Digital hard drive that I have has ShockGuard technology built in, which does the same thing of detecting motion and protecting the head of the hard drive as does the Sudden Motion Sensor. Can the two technologies conflict with each other and cause the system to freeze more frequently due to the amount of spin ups and spin downs.

    No, they don't conflict with each other. You shouldn't disable the Mac OS X SMS.

    I have disabled the Sudden Motion Sensor and so far, so good, this has stopped the system freezing for a second or so when I hover the mouse over the dock or want to save a document. The noise of the hard drive spinning up and down has also decreased.
