you plug in the HDD to the adapter, then you plug the power adapter in and attach to the HDD, then attach ti USB Cable to the Adapter and plug it in... you should hear a CHING, that the USB is seen, if you can not see the HDD now, in your list, that means it need to be initalized... that can be accomplished by open Disk Management - let the module load and then you should see a new HDD that shows - select it and initialize it, next format it, next set it to Active..... now you should be able to see in as a External HDD - select eject the HDD or USB Device. unplug all the cables, put your adapter up. then insert the HDD into you Computer and follow the Restore, the RESTORE Program will Format as it needs, set all partitons as needed and install your OS... it then will/should auto reboot into the HDD and you will see almost exactly as the Factory Sent.... just follow all instructions.. like when it was NEW
