Pausing WD TV Live Plus

I have the WD TV  connected to My Home Network and a 2 TB external  with my movies connect to the WD TV.  There is a user who streams movies to her PC and sometimes pauses the movie for up to 30 minutes.  There are times when she forgets and its on pause for hours.  Is this harmful to my WDTV and External drive?  Thanks

Not to the WD, and I’m guessing not to the HD.   Since it’s not reading data, your HD should go to idle.
