WARNING: Hard drives require careful handling, especially when
being transported. If you are not careful with your hard disk, lost data
may result. Always handle your hard drive and storage device with
caution.

Driver Installation
No driver installation is required for these operating systems, as this
enclosure is natively supported, so the drivers are already installed.
How to Congure
Operating Modes
Mode Description
RAID 0
(Striping)
Striping combines multiple disk into a single large
disk array. The data is split evenly across each disk
simultaneously. Read/write performance is increased as
a result, but failure of any one disk will make the entire
array unusable.
RAID 1
(Mirror)
Mirroring writes the same data across multiple disk,
creating exact mirror copies. This provides redundancy
in case one drive fails.
JBOD
(Single)
JBOD enables each hard drive to be seen separately.
This should be used if only a single hard drive is
installed.
NOTE: When using eSATA, JBOD should only be used
if the eSATA host controller provides Port Multiplier (PM)
support. If a host is not PM-aware, only a single drive
will be visible. No such limitation exists if using the USB
connection.
BIG
(Concat)
BIG concatenates multiple hard drives into a single large
disk. Provides no performance or redundancy benefits.

Using the Storage Device
Windows 2000/XP/Vista/7
If you are using a brand new hard drive that does not contain any data,
then you will first need to prepare the hard drive for use. From the
main desktop, right-click on “My Computer” (“Computer” in Vista/7),
then select Manage. In the new Computer Management window, select
Disk Management from the left window panel.
Locate the Disk that says it is “Unallocated” (check hard drive capacity
to confirm it’s the correct hard drive) and then right-click in the section
that says “Unallocated” and select “New Partition”.
6
The New Partition Wizard will appear. Follow the instructions in the
wizard to complete setting up the drive. Once complete, the Disk
should show up as “Healthy” with a drive letter assigned (i.e. E:). This
drive letter should now appear within My Computer.
If you are installing a hard drive that already has data on it, then after
plugging it in, the drive should automatically show up with a drive letter
assigned within My Computer.
