Does anyone know if there is a way to defraggment an external HD connected to my HD24 using an eSATA cable. I am using a 2TB FantomeDrive HD and because all storage is either on your internal or external drive, there's no using both - when it gets 50% full or more it starts slowing down/freezing my menu & guide. It's real bad when I try to select a an On-Demand channel like 1000 or higher. I was @ 85% and it did get much better when I deleted 35%. But I figure there is a lot of data gaps just like on your computer when you delete stuff. I think it's slowing down the speed at which it can search for stuff on the HD. Any thoughts?
