My small 2.5' external drives show on pc but won't show up on my media center, which is what I bought them for. This is obviously an inadequet power problem, at least that's my guess. I've even tried routing them through a powered hub to no avail. Does anyone out there have an idea how to kick these in the butt a little to get them to show? The storage issue the bane of my HTPC experience, not to mention most expensive.
