i am having problems with the dock staying connected. every time i set recordings it goes back to the internal drive, other than that i have no problem using the exteranl dock with it. it seems like every time i set 2-3 recordings real close together time wise something happens that it somehow goes back to the internal hard drive. anybody have a clue what in the world is happening? i am using the black x external dock with a western digital AV-GP 2TB.
