Is the 3TB GPT or MBR ? (and with that question what are your other “working” hdd formatted)
Some TV’s don’t like GPT Partitioning (and may only be compatible with MBR)
in Windows … click ‘Start’ then in the search box type
diskmgmt.msc
then click on diskmgmt.msc to open Disk Management … then Right Click on your HDD (it will be Disk 1 or Disk 2 or Disk 3 etc. then “Properties” and the “Volumes”
