Wd elements 2TB cannot be accessed on Samsung TV?

I have tried to plug my hard drive into the USB port of my Samsung TV and when I press “media.p” on my remote it states “there is no device connected” the led power light on the drive is on, any suggestions on what is going wrong?

Please can someone help!!!

I just bought it Today. The Wd Harddrive has to be formated to exfat, then it just works perfectly fine for my 2019 Samsung crystal Uhd 43 Inch Tv.
