Re-Inserting Drives
If the E14 or E16 error appears on the Dashboard in Settings and NAS Navigator2 after initial bootup, follow the
procedure below to re-insert the internal drives.
1 Turn off the TeraStation.
2 Open the front cover with the included key.
3 Push a drive’s unlock button and swing the lock mechanism out.
4 Pull out the drive cartridge and remove it from the TeraStation.
5 Insert the drive back into the same slot with the lock mechanism remaining open.
Push here to insert.
6 Swing the lock back down until it clicks into place.
7 Repeat steps 3–6 for all other installed drives.
8 Once every drive has been re-inserted, close the front cover.
9 Press the power button on the TeraStation.
10 Make sure any error messages have cleared from the LCD panel.
The drives are now inserted properly.
Creating a USB Initialization Drive
We recommend creating a USB initialization drive as soon as possible. This USB drive can be used to initialize the
TeraStation’s settings to its factory default values or recover the system if your TeraStation encounters an error
that prevents the unit from booting. For the detailed procedure, refer to the“Creating a USB Initialization Drive”
subsection in chapter 7.
