wonder if any of you have any advice for me. I can't seem to get my External HD (seagate) onto my Dell Laptop. It won't recognise it. The lights on my HD light up but the Laptop won't show me that it has seen it.
Does the drive spin up? USB 2.0 ports are current limited to 500mA, wheres a typical 2.5" drive requires about 850mA during spin-up. Some ports can handle the extra current demand, others can't. In the latter case you can use a USB Y-cable to pick up power from two ports.
