Dismounting Drives
If the TeraStation is powered on, dismount drives (internal and external) before unplugging them. You may dismount external drives with the function button, or any drive from Settings. If the TeraStation is off, then all drives are already dismounted and may be unplugged safely.
Note: Do not dismount internal drives while a RAID array is rebuilding or RMM is being configured. If you do, data on the drives may be lost.
Dismounting with the Function Button
Hold down the function button for 8 seconds. The function button will light up blue for 30 seconds as your USB drives are dismounted. When the dismount is finished, the function button's LED will turn off, then come back on. You may now unplug any USB drives safely.
Note: After 60 seconds, the function LED will go out and any drives that have not yet been unplugged will be remounted.
