Adding a external drive to the Directv streaming service

I am trying to add a USB External Drive to my streaming box, but it keeps crashing and only shows the Directv space ship Logo when I have the USB Drive connected. I also have a Digital Audio connection to my home theater system and I don’t know if it’s too much of a power drain or something else. When it does come on it crashes and restarts often now with or without the external drive connected to it. I have looked at the support site, google and YouTube videos but all I can find is information about using an external drive for the Satellite DVR nothing to add on one to the DIRECTV STEAMING box. Also I recently had to install a new or different streaming device when the other one stopped working correctly and now this one is having issues, freezing up and shutting down, losing connection and sticking to the spacecraft logo. Is there any additional Apps or software that I need to install on the USB drive or to the streaming device from the google App Store? Please advise me about this issue and if you think that I will need another streaming device since this one is acting flaky. Thanks for your assistance with these issues.
