If it gets stuck in boot, it is most likely a bootloader issue, that chokes on the NTFS filesystem. Why would you use NTFS on a linux box?
because with ntfs, recording doesn't stop if the file size reaches 4GB. I never had any issues with the zgemma star H2 and the same nfts usb flash drive.
I've tried now to initialize the flash drive from the setup in ext4, rebooted and the decoder got stuck again in boot.
