WD MY PASSPORT 1 TB Hard Disk not working in TV

[JoeySmyth]

Your tv probably doesn’t support GPT Partitioning and only support MBR.

Why do only 3 of my 5 Ultras work with TV?

I have 5 My Passport Ultra 2TB devices, three purchased 3 years ago and 2 last year. The older three work perfectly on my Samsung HD TV and Smart TV, but the 2 most recent say there is nothing on them when connected to the TV, though all 5 work on my PC. All are formatted to NTFS. All contain movies and TV shows. Does anyone know why the latest 2 do not work?
