Hi there Peter and welcome
It is always best to use a drive with it's own power supply, as it ensure it receives the correct power at all time. If you get too many connected devices on the TV, it can lessen the output creating issues.
I would advise you go with the MyBook that has its own power supply, this will be the best solution for you Peter.
Is there any additional information you would like?
Please let me know
