Re: disk

Are you sure your devices are compatible with so large a disk that is partitioned in another way (GPT) than smaller disks (MBR)? What does the user manual say? What does Panasonic customer service say?

If not supported, your choices are limited:
1. Use a smaller MBR formatted disk
2. Buy devices that can handle GPT partitioned disk
3. Wait until Panasonic issues new firmware for their devices.
