Hello, I am a newbie. Recently I have purchased LG42LB6500. I have two 1TB WD my passport, whereas one is loaded with all movies,music,data and other is loaded with just some files less than 1GB. The strange problem I am facing is that one of my 1TB WD (which has only files) is getting detected when connected to TV whereas the other (which as all movies,music,data) doesn't. Can anyone help me on this. Here is additional info: Later, after connecting, I just waited and then surprisingly the second 1TB WD (which as all movies,music,data) also got detected but has taken almost 20 mins of time. I could able to see the folder structure on the TV and even tried playing a movie. Noticed that the movie was running, I could see the seekbar is running but am not able to hear (or) see the movie. What could be the problem?
