2.2 Replacing Hard Drives

When one of the drives fails, the Rebuild LED will light up orange and the corresponding
HDD LED will light up red. If only one drive is defective and the RAID mode is set to RAID
1, RAID 5 or RAID 10, the data can still be accessed but we strongly recommend
replacing the faulty drive immediately to assure continued backup and data safety.
If more than one drive at the same time fails or if the RAID mode is set to RAID 0 or
Spanning, the data will be lost and the system can not be accessed again until the drive(s)
have been replaced.
1. Check the HDD LED and replace the faulty drive. The red LED indicates the defective
HDD. The power does not have to be turned off when replacing the drive(s).
2. A few seconds after installing the new drive(s) the corresponding LED will turn green.
3. For RAID 1, RAID 5 and RAID 10, the RAID array will be rebuilt automatically. During
this process, the Rebuild LED will blink orange. Rebuilding the RAID array will take
several hours, depending on drive capacity.
4. For RAID 0 and Spanning, erase the old partition, create a new one and then format
the drives again.
Note: We recommend not turning off the power during the rebuild process but if it is
interrupted, it will continue rebuilding the data as soon as the power is turned back on.

2.3 Connection to Computer

A few precautions and notes when using your external storage drive:
Check the cables for visible damage before turning it on
Do not expose the product to water or humid conditions
Do not cover the enclosure's ventilation holes
Only one interface can be used at any given time.
When more than one cable is connected, the eSATA connection has priority. To use a
different interface, disconnect the other cables first, before connecting the new one.
Before connecting the device, install the hard drives and set your preferred RAID mode.
For the safe removal of your drive and to assure that no data is lost, always follow the
correct unplug procedure for external hardware (e.g.: Eject the drive before removal).
For volumes larger than 2TB, your Operating System also needs to support it in order
to access the drive (e.g. 64-bit System).
