3TB hdd formatted on exfat has capacity of 3tb but does NOT show when connected to another device (usb dvd player) 3TB hdd formatted on fat32 has capacity of 801GB but DOES show on device. But this is a waste of 2+TB. Why does this happen or is there anyway around this? I have a 1TB hdd format fat32 and it has full capacity and also plays on device. I don't understand as both are formated same way and have same files on both. Any help/advice appreciated.
