Download wdidle3 from Western Digital and the instructions are there on how to to disable the Intellipark feature. You can download a copy of it here, http://support.wdc.com/product/download ... 09&sid=113. There are videos on YouTube that will show you step by step on how to do this as you will need to boot in DOS to run the patch. If you do this then you're pretty much good to go.
If you're a casual home user who will be using this drive as it was intended, running the patch isn't necessary (IMHO).
