22
REBUILD
If one of the HDDs fails, the Disk LED will become red, and the rebuild function
can be set up under RAID 1 mode. To setup Rebuild under RAID 1 mode,
please complete the following steps:
The use of identical HDDs from the same manufacturer, with the same
capacity and RPM is highly recommended.
1. When the failed HDD is removed, a popup window stating “Attention! Hot
Swap” will appear. Click on “Ok” icon to continue.
2. Another popup window will appear stating, “Attention! RAID 1 Degrade
Mode”. Click on “Ok” to continue.
When one of the HDD has failed, the Disk LED will become red. However,
no warnings will appear on RAID MASTER to notify the user. Please pay
attention to the Disk LEDs at all times.
23
3. Then, the “Rebuild” option should appear. Continue by replacing the
failed HDD with a functional HDD or inserting a New HDD in place of the
one removed. The New HDD will show up as red “New” and “Not Config”.
To rebuild the New HDD (the new functional HDD) with the data from the
Old HDD (the remaining functional HDD) sector by sector, click on the
“Rebuild ==>” icon.
The New HDD may be inserted into either Disk 1 or Disk 2, because the
Rebuild feature can be performed in either direction.
24
4. A popup window stating, “Copy Data From Disk 1 to Disk 2. All data in
Disk 2 will be lost. Continue?” Click on the “Yes” icon to confirm.
5. During the rebuild, a “Rebuild Percentage” status window will appear and
the information under “RAID Status” and “Disk Information” sections
should reflect the same.
If data is accessed while the chipset is processing the Rebuild task, the
speed of data access may vary or decrease. Hence, data access of the
HDD(s) during Rebuild is highly not recommended.
Even if the RAID Unit loses connection to the host, the Rebuild will continue.
If the RAID Unit is powered off, the RAID Unit will retain the Rebuild status in its
memory. When the RAID Unit is powered “on” again, the Rebuild process will
resume from the previous status.
25
6. After the rebuild is completed, data from Old HDD will be copied onto the
New HDD under RAID 1 mode.
The Rebuild feature is only available under RAID 1 mode. If the “Rebuild”
option tab is selected under any other RAID mode, a popup window will appear
stating, “Attention! There should be two disks with at least one RAID 1 disk for
Rebuild Mode."
26
MIXED RAID STATUSES
When a New HDD that’s been formatted with a certain RAID mode in another
RAID Unit (specifically DataTale AIR) and is placed into the current RAID Unit
along with an existing HDD, a “Mixed RAID” status will result. Under this
circumstance, the New HDD can be re-formatted as JBOD (None RAID) mode.
To do so, please complete the following steps:
1. The New HDD will appear as “RAID 0 (Broken)”, or other variations
depending on the situation for other RAID modes. The existing HDD will
appear as “JBOD” for individual HDD, or other variations depending on the
situation for other RAID modes.
2. To erase the previous formatting in the New HDD, click the “Delete RAID
Info” icon under “Disk Information”.
“Delete RAID Info” will erase all data stored on the New HDD. If you have
important saved data in the New HDD, backup all data before selecting “delete
RAID Info”.
27
3. Once completed, the New HDD is ready to be used as JBOD or combined
with the existing HDD under a chosen RAID mode.
28
DEVICE INFORMATION
To retrieve Device Information for the inserted HDD(s) of the RAID Unit(s),
please connect the RAID Unit(s) to the host and open the RAID MASTER. Once
connected, click on the second sub-menu icon (bottom) to see the information:
The connected RAID Unit(s) information with Device model of the RAID Unit(s),
and serial numbers of each inserted HDDs.
Because the RAID MASTER can manage “more than one unit of the RAID
Unit”, each RAID Unit connected to the host computer will reflect as “Device __”
and in numbering order “Device 1, Device 2, …” respectively.
Due to chipset configuration, the Device List will reflect the HDDs as “M0
and M1” for “Disk 1 and 2”, respectively.

31
DISK VOLUME OVER 2TB
The 2+TB HDD support is determined by the chipset used in the device and the
operating system itself. The RAID Unit supports and recognizes 2+TB HDDs, but
the actual 2+TB support will vary depending on the different operating systems
used.
If the OS does not support over 2TB, you can still use the RAID Unit by NOT
checking the “Over 2TB” option under the “Configuration” option tab. The RAID
MASTER should automatically re-adjust the available HDD(s) storage capacity
and format the chosen RAID mode under 2TB. Please see “Over 2TB” section
under Q&As for more information.
SAFE REMOVAL OF THE RAID UNIT
Safe removal of the RAID Unit from the host controller is highly recommended,
especially when switching interfaces. In order to safely remove your RAID Unit
from the host controller, you would need to eject the device on your host
controller system.
32
RAID MODES
A Redundant Array of Independent (or Inexpensive) Disks (RAID) is a system
that utilizes multiple hard drives to share or replicate data among the disks. The
benefit, depending on the selected RAID Mode (combinations of disks), is one or
more of increased data integrity, fault-tolerance, throughput or capacity when
compared to single drives.
Deleting the current partition prior to changing RAID modes is highly
recommended.
Using identical HDDs with the same capacity and RPM, and from the same
manufacturer are highly recommended for best capacity utilization.
RAID O (STRIPING)
RAID 0 (Striping) is a performance-oriented, non-redundant data mapping
technique. It combines multiple hard drives into a single logical unit. Instead of
seeing several different hard drives, the operating system sees only one large
drive. Striping splits data evenly across two or more disks simultaneously,
dramatically increasing performance.
Striping can be implemented in disks of differing sizes, but the storage space
added to the array by each disk is limited to the size of the smallest disk.
Although Striping is an easily implemented, simple configuration, Striping should
never be used for mission critical applications. The speed of operation is
excellent in comparison to other RAID modes.
33
In Striping mode, if one disk in the RAID Unit fails, all data in installed disks
will be lost.
RAID 1 (MIRRORING)
RAID 1 (Mirroring) consists of at least two drives storing duplicate copies of the
same data. In this mode, the data is simultaneously written to two disks. Thus,
the storage capacity of a two-disk array is combined into a single disk and the
capacity is limited to the size of the smallest disk.
RAID 1

Disk 1
Disk 2
In Mirroring mode, if one of the disks fails, either source or backup, the data
is still available. However, if the Old disk fails during the Rebuild process, the
data in both disks will be lost.
SPAN (LARGE)
Spanning provides another maximum capacity solution, which some call it as
“Large”. Spanning combines multiple hard drives into a single logical unit.
Unlike Striping, Spanning writes data to the first physical drive until it reaches full
capacity. When the first disk reaches full capacity, data is written to the second
physical disk. Spanning provides the maximum possible storage capacity, but
does not increase performance. 34

JBOD (NONE RAID)
Just a Bunch of Disks (JBOD) refers to a group of hard drives. In JBOD, the
number of logical drives is equal to the number of physical drives. This mode
allows the RAID Unit to operate as a multi-disk storage enclosure, but provides
no data redundancy.

Q&As
GENERAL
Q: How do I choose the proper RAID mode for my RAID Unit based on the tasks
I need to perform?
A: Since the RAID Unit is a “Mass Storage” device, which means its size
capacity is sufficient for data management, the different RAID mode settings can
help you administer the enormous data storage from the HDDs combination. It is
highly recommended to choose the RAID mode based on what is the essential
factor to complete your task. The most common three factors are size capacity,
speed, and data protection. For example, if using the RAID Unit to simply watch
films for enjoyment or for storage, the JBOD and SPAN modes are perfect
because they can maintain decent speed and still have a large storage capacity.
If the work requires instant and continuous backup of data such as for a writer or
editor, then RAID 1 would be the best choice. However, if immediate data
access is required such as business professionals, RAID 0 would be more
appropriate.
DAISY CHAIN
Q: Because there are two (2) FireWire ports on the RAID Unit, I connected them
to my other two (2) external devices. Why can’t I see these additional external
devices on my host? I’m using the USB connection from the RAID Unit to my
host.
A: In order for the “Daisy Chain” feature to work properly on the RAID Unit, one
of the FireWire ports need to be connected to the host, and the other one can be
connected to an external device. The computer will not recognize different
interfaces if they are all used at the same time.
OLD HDDs
Q: My old hard disk(s) have data inside. Will the stored data still be recognizable
if I just install them into the RAID Unit?
A: Please backup all existing data from the old hard disk(s) before installing them
into the RAID Unit. Once the old hard disk(s) are inserted and setup for a
chosen RAID mode, the RAID MASTER will automatically re-format the disks
and all the old data will be lost.
HDD SIZE
Q: Can I use one 2.5” 9.5mm thick SATA HDD, and one 2.5”12.5mm thick SATA
HDD inside the same RAID Unit? Will the RAID Unit be able to recognize them?
A: Yes, the RAID Unit can support both 9.5mm and 12.5mm thick 2.5” HDDs.
39
HDD CAPACITY
Q: I would like to format my hard drives with the FAT (a.k.a. File Allocation Table)
format, which can be read and written by both Mac and PC. Is there any
limitation on its capacity?
A: Yes, please check the table below for reference.

DISCREPANCY IN REPORTED & ACTUAL SIZE
CAPACITY
Q: If I have a 750GB HDD, why does the RAID Unit only recognized the HDD
available space as to be less than 750GB?
A: Many customers are confused by their host systems when it reports a
discrepancy between reported capacity and actual capacity. Several factors can
come into play when your host system views and reports the capacity of a hard
drive. There are actually two different numbering systems used to express units
of storage capacity:
Binary, which says that a kilobyte is equal to 1024 bytes; and
Decimal, which says that a kilobyte is equal to 1000 bytes.
Most commonly used to display storage capacity is in Decimal. The surprising
fact is that even though it seems like you will have more bytes under Binary, the
Decimal calculation system actually presents a greater storage capacity. More
description on capacity issues can be found at the Seagate website under FAQs.

REBUILD
Q: Does the RAID Unit have to be connected to the host computer when it is in
rebuild mode?
A: No, it does not have to be. The RAID Unit can support offline rebuild, which
means it can perform the rebuild function without being connected to a host
computer.
RAID MASTER: CONNECTION RESTRICTION
Q: Is there any connection restrictions for the RAID MASTER?
A: Yes, the RAID MASTER can only be operated via USB 2.0 or FireWire 800. If
you choose to use eSATA for data transferring, please set up the RAID
configuration via USB or FireWire first.

OVER 2TB
Q: What is the “Over 2TB” option for under PC’s version of RAID MASTER?
A: The HDD(s)’ storage capacity can affect RAID Unit’s operation depending on
your host’s PC OS. Some older PC OS can only function the RAID Unit under a
particular size limitation (please see “DISK VOLUME OVER 2TB” for more
information). If the host can support more than 2TB HDD(s) storage capacities
and the HDD(s) is/are over 2TB, check the “Over 2TB” option under the
“Configuration” option tab. Because the Unit requires OS 10.4 and above for
MAC, which automatically supports over 2TB, the “Over 2TB” option would not
appear under the RAID MASTER for MAC.
This popup window may appear if the host’s OS cannot support over 2TB of
HDD storage capacity, similar to the picture shown below. Click on the
“Yes“ icon to continue.

LINUX
Q: Can I use this RAID system under Linux OS?
A: Yes, but the RAID System must first be set up under Windows or MAC OS via
USB 2.0 or FireWire connection before using it under Linux OS.
