Recommended Internal Drive
An external USB hard drive can be connected to the NVS2801 via the ‘Ext HDD ’ slot of the NVS2801. This allows users to make secondary copies to external USB drives without using a computer for additional data safety. External hard drives must be formatted using exFAT file system. Connect the AC adapter to the NVS2801 before connecting the USB device. The NVS2801 does not detect USB devices without external power connected.
