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