Are you using an external HD on a laptop and the hd uses the usb for power? I couldn't tell you how many times I come across this, but people think their usd hd doesn't work anymore. When the reality is they are drawing too much power from other things. For example laptop+hd works fine but then they go and plug in an extra monitor, keyboard n mouse, etc, and the hd and the hd doesn't show up. Because it doesn't have the capacity to draw the power it needs from the usb.
