Hard disk esterno non riconosciuto dalla tv

Good morning everyone. I have bought a 1TB WD for a couple of days, which is read perfectly by the computer, but not by the TV which says there is a problem on the disc. I have recently tried to connect the hard disk to the other TV I have at home and it works perfectly. Note that the TVs are of the same brand, or LG. I have already read all the other discussions about this problem in this forum, but I could not change that. thanks a lot
