Congratulations on your new DriveStation Duo! With dual hard drives, the
DriveStation Duo gives you many options for large capacity and easy-to-use
redundancy.
Insert the DriveNavigator DVD into your computer’s DVD-ROM drive.
DriveStation Setup
On a PC, DriveNavigator should automatically launch. If
it does not, manually launch [DriveNavi.exe] by clicking
[Start] and selecting [Run]... [option]. When the Run
dialog opens, type [d:\DriveNavi.exe] (where d is the
drive letter of your DVD-ROM drive). Click [OK] to
continue.
If you are installing the RAID utility on a Mac, open the
DVD and click [RaidUtility.dmg] to begin installation.
Click [Begin Installation]. Click [Next] to
step through the installation. Mac users
can skip this step.

5
After completing the setup wizard, your DriveStation Duo is installed and ready to
use!
By default, your Duo is congured in RAID 1 Mode. In RAID 1, data can be
recovered even if one of the hard disks in DriveStation fails. However, the total
available space is 1/2 of the maximum space.
If you prefer a different RAID conguration, or if you prefer to use DriveStation
as a single drive, you may use the RAID Utility to change your DriveStation’s
RAID settings. Turn to the next page for instructions on using the RAID Utility.
Out of the box, the DriveStation is formatted with FAT32, allowing it to be used
with most common operating systems. If you’re going to use it with programs
that generate lesizes larger than 4 GB, such as backup software, reformat the
DriveStation with NTFS or Mac OS Extended.
By default, all drives on the DriveStation are divided into 2 TB partitions. This
allows older versions of Windows, such as 32-bit Windows XP and Windows
Server 2003, to read the drives without additional software or service packs.
Users of newer operating systems may wish to re-partition the DriveStation with
larger partitions, but this is not recommended for 32-bit Windows XP. Windows
Server 2003 may be able to read larger partitions after the latest service pack is
applied.
The wizard will step you through setting up your DriveStation Duo, conguring
your RAID settings, and reformatting if desired.
The DriveStation Duo may be connected to your computer with either a USB
connection or an eSATA connection. The eSATA connection will usually give
higher performance.
Use either the eSATA cable or the USB cable to connect the Duo to your
computer at any given time. Do not connect both at once!

6
Using the RAID Utility
The RAID Utility allows you to congure your DriveStation Duo in several modes:
Normal Mode - Appears to your computer as two separate hard drives. Note that
normal mode only works with a USB connection. With an eSATA connection, only
one drive will be visible.
Spanning Mode - Appears to your computer as one large hard drive.
RAID 0 Mode - Appears to your computer as a single drive. Higher performance
than Spanning Mode.
RAID 1 Mirror - Appears to your computer as a single drive. The second drive is
an exact copy of the rst drive, for redundancy.
Notes:
・Changing the mode of the drives in your Duo will erase all data on them! Back
up any important data before using the RAID utility.
・Your computer must be connected to the DriveStation via USB to change the
RAID mode.
On a PC, You may launch the RAID Utility by clicking on [RAIDUtility] in the
DriveStation Duo program group.Or, you can launch the program from the Start
menu.
On a Mac, Double-click [RaidUtility] icon on your desktop.

7
Using the RAID Utility
Once launched, the RAID Utility will briey scan for your DriveStation
Duo. This may take a few seconds.
The initial screen will show your current conguration. If your Duo is
new, it will probably be in RAID 1 mode.
To change the RAID mode, click [Cong] and choose [Disk Cong].

8
Using the RAID Utility
Select the drive structure that you’d like to use.
On a PC, the disk can be formatted with FAT32 or NTFS. Select the
format that you prefer. FAT32 is compatible with most Windows PCs
and Macs. NTFS offers the best performance with Windows, but isn’t
compatible with Mac. NTFS is recommended for use with backup, video
editing and other programs that may need lesizes larger than 4GB.
If you are using Windows XP, or Windows Server 2003 without SP1 or
later, use compatability mode. Compatability mode will divide drives into
2 TB partitions that can be read by Windows XP or Windows Server 2003.
Click [Yes], and [Yes] again. Understand that this will erase any data on
the drive!

The following is a list of common issues with the DriveStation. Following
each issue are possible resolutions.
I cannot see the DriveStation in My Computer. (Windows)
Verify that the POWER light is on. If it is not, then ensure that the
power switch is in the AUTO position.
If you have installed the Power Save Utility, then verify that the
DriveStation was not put into power saving mode. Consult the
manual for the Power Save Utility for additional help. The manual
can be found on the DriveNavigator DVD-ROM.
Verify that the hard drive inside the DriveStation is spinning. This
can be veried by placing your hand on the sides of the case
and feeling for a slight vibration. Also, after the DriveStation has
been powered on for fteen minutes or more it will begin to get
warm. If neither of the proceeding tests veried that the hard drive
is spinning, then please contact technical support for further
assistance.
My backup program can’t save les to the DriveStation.
Reformat your DriveStation with NTFS or Mac OS Extended.
FAT32 is limited to 4 GB lesizes.
