      An external hard drive MUST be plugged into a USB port that can actually supply 500 ma of current (amperage). .

      It may NOT be detected correcly if it’s plugged into a USB port in an external hub or on the front of a desktop case.

      In addition to the info there….

      For some desktop mboards you can have problems when an external hard drive is plugged into one of a pair of USB ports on the back of the case that are connected to the same USB controller, if there is another device plugged into the other USB port for the pair, because the pair can’t actually supply 500 ma per port – they can only supply 500 ma in total. Usually those pairs of ports are one above the other, not beside each other. If you have two devices plugged into such a pair of ports, try plugging one of them in elsewhere on the back of the computer.

      For MANY laptop and netbook mboards similar applies. The built in USB ports often cannot actually supply 500ma per port – they supply 500 ma in total for two ports that are close to each other. In that case, the external drive should work fine if it’s the ony thing plugged into the USB ports built into the laptop or netbook, or if you have more than two ports, the only thing plugged into two ports close to each other.

      If that doesn’t help, here’s a reference I found on a Seagate forum about a problem with the same series of drives…

      “Here is a link to our external troubleshooter. If none of the steps help, we would recommend that you take the drive back to the place of purchase since it was recently purchased.
