It SHOULD work. Although I copied the contents of the original drive to the new drive, the first step of the process is to initialize the new drive in the DirecTv DVR just like you did. My only suggestions would be to test the new drive in a PC, recheck the cables, and also make sure any transfer speed jumper is set properly. If those steps check out, you have a bad drive
