If your Operating System does not support single volumes larger than 2TB, make sure the 2TB volume switch on the 4500MGB Quad Bay is at position B, so that larger volumes are automatically split into two smaller ones.
The 2TB LED indication will light up when the total capacity of the installed hard drives exceeds 2TB. This is not related to the RAID mode but an indication to remind you that a single volume will exceed 2TB in capacity.

2TB Volume Switch
When the total capacity of the installed drives exceeds 2TB, the 2TB LED will light up. When the 2TB switch is set to B, volumes larger than 2TB will automatically be split into two smaller volumes (A+B / C+D). If your Operating System supports volumes larger than 2TB (e.g. 64bit OS), setting the 2TB switch to A will create one large volume instead.
Smart Fan
The smart fan automatically regulates the fan speed according to the internal temperature. It will start using low speed from 0­44 degrees, increase the speed every 5 degrees until 60 degrees and use full speed above 61 degrees Celsius.

When adding more drives without changing the RAID mode, the hard drives do not have to be re-formatted again.
The device does not have to be turned off when adding or replacing a faulty hard drive.
The data can still be accessed when a drive in the SAFE mode fails but we recommend replacing the faulty HDD immediately to assure continued backup and data safety
Adding more Hard Dri ves
For the BIG and SAFE mode, it is possible to start with less than 4 drives and installs more at a later point.
1. Remove the front panel and install the additional drive(s).
2. Press and hold the CONFIRM button for 3 seconds. The 3 RAID mode LEDs will light up twice at the same time to confirm when the setup mode has been accessed.
3. Release the CONFIRM button.
4. Without changing the RAID mode, press the CONFIRM button again to save the settings.
5. The device will now automatically reset itself and add the new drive(s).
6. Mount the front panel.
Replacing a faulty Hard Drive
When using the SAFE or SAFE II mode, a faul ty hard drive can easily be replaced and the data restored automatically.
1. When one of the drives is defective, the ERROR LED will light up red.
2. Remove the front panel and check which of the drives has to be replaced. The corresponding LED from A-D will be blinking red and green to indicate the defective drive, instead of a steady green for normal operation.
3. Remove the defective drive and install the new one. It will automatically start to rebuild the RAID array.
4. The REBUILD LED will light up green and the corresponding HDD LED will light up red and blink green at the same time during the rebuild process.
5. Mount the front panel and let it finish the rebuild process.

Connection to your Computer
A few precautions when using your external storage enclosure:
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 v ent il ati on hol es
Hard Disk Mode
When using your 4500MGB Quad Bay and more than one interface cable is connected, the USB connection has the priority. To use a different int erface, make sure to disconnect any of the other cables first, before connecting the new one.
When the device is turned on, the hard drives will keep spinning to provide immediate access to the data even when the Operating System goes into stand-by mode, so when not in use, we recommend always turning off the power.
RAID Setup
To change the RAID mode, rem ove the front panel to access the CONFIRM and MODE buttons. Keep in mind that when changing the RAID mode, the drives have to be re-formatted, so all data will be lost.
1. Press and hold the CONFIRM button for 3 seconds until the three RAID mode LEDs blink two times.
2. Press the MODE button to select the different RAID modes. It will cycle through BIG/FAST/SAFE/SAFE+FAST (SAFE II).
3. Within 10 seconds after selecting the new mode, press the CONFIRM button to save the setting or otherwise it will revert back to the previous setup.

If the total capacity exceeds 2TB and your Operating System does not support single volumes over 2TB, set the 2TB switch to position B and it will automatically split the volumes (A+B / C+D).
For the FAST mode, hard drives of identical capacities are recommended. If different, the total amount of the space that can be used will depend on the drive with the smallest capacity.
BIG (JBOD spanning)
The drives show up as one large single volume. Spanning is an array (not RAID) that is written sequentially across the drives. By itself, it does not provide any performance or redundancy benefits. Use this if you have installed 1-4 hard drives with different capacities.
FAST (RAID 0 striping+striping)
The drives show up as one large single volume. This mode requires 4 identical drives to implement. Used where speed is the primary objective, RAID Level 0 (also called striping) is not redundant. This for m o f arr ay splits each piece of data acr os s the drives in segments; since data is written without any form of parity data-checking, it allows for the fastest data transfer of all other modes. However, if one drive becomes damaged, the whole array can become corrupted.

For the SAFE mode, hard drives of identical capacities are recommended. If different, the total amount of the space that can be used will depend on the drive with the smallest capacity.
If the total capacity exceeds 2TB and your Operating System does not support single volumes over 2TB, set the 2TB switch to position B and it will automatically split the volumes (A+B / C+D).
SAFE (RAID 1 mirroring)
The drives show up as two volumes, each representing one set. This mode requires 1 or 2 sets of 2 identical drives to implement. RAID 1 creates an exact copy (or mirror) of a set of data on the second drive. This is useful when reliability and backup are more important than data capacity. The available capacity to the user will be 50% of the total capacity for each set but when one hard drive fails, it can be replaced and the data rebuilt automatically.
SAFE II (RAID 10 mirroring+striping)
The drives show up as one single volume. This mode requires 4 identical drives to implement. RAID 1 creates an exact copy (or mirror) of a set of data. This is useful when reliability and backup are more important than data capacity. The available capacity to the user will only be as large as 50% of the total capacity of all drives combined but when one hard drive fails, it can be replaced and the data rebuilt automatically.

If the drive does not appear, make sure the drivers are installed properly and the power is on.
Mac OS can not write to NTFS formatted drives. To use your device on both platforms, we recommend using FAT32.
If the total capacity exceeds 2TB and your Operating System does not support single volumes over 2TB, set the 2TB switch to position B and it will automatically split the volumes (A+B / C+D).
Partitioning & Formatting
Be aware that this will destroy all your existing data on the drive, so make sure you have a backup! This step is usually only required the first time you install a factory new hard drive, if you change the RAID mode or want to erase all data on your drive.
PC running Windows
For Windows, use the disk management program:
Right click on “My Computer” and choose “Manage”
Select “Disk Management”
Choose the drive you want to format and right click on it for
further commands (Choose New Partition)
Follow the Partition Wizard to setup the drive
For Win2000, WinXP and Windows Vista, we recommend formatting the drive using the NTFS file system.
If you are using the FAT32 file system to format the drive on Win2000, WinXP or Windows Vista, the biggest single partition you can create will be 32GB. To create larger partitions, you need to use a 3rd party application or change to NTF S for mat .

Mac OS
For Mac OS X, use the disk utility to format and create partitions on your external disk.
Select “Disk Utility” in the utilities folder
Choose your external drive and format it according to your
requirements
For Mac OS X, we recommend formatting the drive using the native Mac file system HFS+ also known as Mac OS Extended.
If you want to use your drive on a PC running Microsoft Windows as well as on your Mac, we recommend using the FAT32 file system. On your Mac, select MS-DOS when formatting it. Note: The file size for a single file on FAT32 is limited to 4GB.
