If you connect only the power and the Universal Drive Adapter (UDA) to your drive without also connecting the USB cable to your computer, the drive will make a click sound. The drive is looking for a data signal to spin up. Once you connect the UDA to a computer you should hear the drive spin up and mount within approximately 30 seconds; this can vary by computer type. If the drive is still clicking check the OS X System Profiler (or a Windows system profiling tool) to see if the UDA is being recognize over the USB connection. If not you may want to restart.
Remember: do not connect the adapter via USB keyboard; it will not provide sufficent power for this device. Use a native USB port on the Mac or PC. If the drive continues to click, disconnect the UDA's USB connection, wait 5 seconds and reconnect it. Wait 30 seconds to hear if the drive spins up. If you still have trouble at this point please contact Technical Support.
