I recently got the Tab S3 and I love it so far. I'm trying to use an 1TB external HDD but I can't find it in "My Files" or anywhere else. I'm using a micro USB hub that allows me to connect a power source as well as the HDD. I also reformatted the HDD to exFAT because of recommendations that I found for mounting older tablets with HDDs. Does anyone know what I am doing wrong? Thanks.
