Buffalo HD-WLSU2R1 DriveStation Duo Manuel D'utilisation page 5

The wizard will step you through setting up your DriveStation Duo, configuring
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!
After completing the setup wizard, your DriveStation Duo is installed and ready to
use!
By default, your Duo is configured 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 configuration, 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 filesizes 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.
