The CXN (V2) will read large capacity hard drives connected to their USB inputs. However, some larger capacity drives will require their own power supply, as the player's USB port may not provide enough power for the drive to function.
The CXN (V2) will support USB hard drives which are formatted to FAT32 and NTFS.
The primary function of the CXN (V2) is as a network music player. The USB ports are intended for convenient connection of USB thumb drives. As such, we cannot guarantee compatibility with all USB HDDs.
