I have a 55 inch OLED55B9PLA TV which Im trying to get to work with a HDD for recording

I bought a SEAGATE Backup Plus External Hard Drive


which ticks all the boxes as is a powered HDD. When I plug it in it recognises it but when I select record it says it cant record to a device attached to a USB hub.

I have plugged the HDD directly into the TV so there is no hub. Anyone know how I can get it to work?

If not, anyone got a list of HDDs in the UK that work with this TV as it states it cant be more than 500mA.

Many thanks!
