Unless your TV has two USB ports, only one hard disk drive (HDD) can be used for content recording at the same time.
If your TV has two USB ports, both can be recognized in the following circumstances:
- one HDD is connected to the USB port labeled "HDD REC", used to record content.
- one HDD is connected to the other USB port, used to play content (pictures, music or videos) through your TV.
NOTE: Connecting HDDs via a USB hub is not supported. Please connect the HDD directly to your TV.
