Just Purchased the LG OLED48A16LA and having problems using an external USB hard drive to record. The drive I have is an Kesu 750Gb usb 3.0 device, I formatted the drive exe fat, plugged into the USB port, the tv recognises the drive but when I try to record I keep getting the message " please use an external usb drive to record " and it recognises the capacity. The drive was formatted for OSX initially and I was just wondering wether this could be the problem. Can anyone lead me to a solution please, perhaps purchasing a new drive pre formatted for windows may help!. Thanks.
