USB Hard Drives
Add a USB hard drive to TeraStation simply by plugging
it in to one of the USB ports on the TeraStation. It will
then appear in the master folder as a new share on the
TeraStation. Not all USB hard drives are supported.
Some USB hard drives may have to be reformatted with
the TeraStation's format utility before working properly.
Before disconnecting USB devices from the TeraStation,
they should be dismounted. Hold the function button
down until it glows blue, and then turns off. It's now
safe to unplug your USB devices.
Note: Unplugging USB devices without dismounting them first may corrupt your data! You may
also dismount your USB device from within System/Storage/Disks in the Web Admin Tool.
