The 851N 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.
While there is no official maximum capacity of USB drive that can be used with our network players, larger drives can take longer to initialise and may experience some browsing delays.
The 851N will support USB hard drives which are formatted to FAT32 and NTFS.
The primary function of the 851N 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.
