The primary function of the EXN100 is as a network music player and the USB port is intended for convenient connection of USB HDDs and SSDs. As such, we cannot guarantee compatibility with all USB HDDs and SSDs.
The EXN100 will read large capacity hard drives connected to the USB Media input. Some larger capacity drives, however, may require their own power supply, as the player's USB port may not provide enough power for the drive to function.
The EXN100 will support USB hard drives which are formatted to FAT32, exFAT, NTFS and Ext4.
