I have a tekram TR-621 and trying to get data off of my laptop hard drive. when I plug it up to the USB, I get the yellow light green light comes on for a short instant. no new hardware found comes up and when I go to my computer it does not show another drive. I've seen where supposedly there is a driver oout there for this but when it never comes up with new hardware im guessing the case may be defective ... any input ?
