Not connecting to smart tv

Old WD Passports use MBR partitions … New ones use GPT partitions

It’s highly likely your TV is not compatible with GPT partition style.

So you’ll have to format it MBR and whatever file system your TV accepts eg. NTFS/FAT32 etc

Note: MBR only supports a Maximum of 2TB (Terabytes) (GPT supports virtually anything Over 2TB)
