Whenever I plug it into my computer none of the lights turn on. When I plug in the SATA Power the ck3 lights come on, but none of the ones on the top half of the unit. Neither device manager or the firmware update tool it is not detected. I've checked all the switches and am really at a lost. I last used it a few months ago, but I no longer have the computer with which it last worked. I have tried it on multiple computers. I have been checking all the forums, and can't find a solution. Thanks in advance for your help!
