(9) Troubleshooting and FAQ
1) If the system experiences an HDD failure:
The LED for the HDD will be o or red and the sounder will
beep (press SET to silence).
2) Can I remove a drive from the RAID and install it in
another enclosure for access to the les?
You can do so for RAID 1(Mirroring), Combine or JBOD. In the
other modes, you cannot remove a single drive and access it
outside of the RAID.
3) Does Mobius remain connected to the host computer
and usable during the automatic mirror rebuild?
You still can access the data when the DataTale is rebuilding, but
since it is rebuilding, the transfer speed will be slowed down.
Please note: The typical rebuild time is 50GB to 100GB per hour.
4) The Mobius is going to sleep. Is there a way to
prevent this?
Please visit Section 8 in this manual for instructions on disabling
hard disk sleep in the Operating System. To also disable the Mobius
auto sleep timer, download the utility under the Resources tab
on the product page (http://oyendigital.com/mobius.html).
Click Advanced and select the option to set sleep to 0 minutes.
NOTE: Turning o the Mobius will reset the sleep timer
to 20 minutes.
5) Can I create a RAID-5 and add drives to the set later?
No. Once a RAID-5 set is created it must be cleared and
re-created to add or subtract drives from the set.
(6) Formatting
If you are installing new drives, you must format the volume
before it is accessible.
1. Connect the RAID to the computer.
2. Congure the desired mode as explained in section 4.
3. After the RAID is congured, use Disk Management on the PC
or Disk Utility on the Mac to format the volume *.

(7) Auto Sleep Mode
* If using RAID 0, RAID 10, RAID 3 or RAID 5, we strongly
suggest performing a low level format after setting the RAID.
Please refer to the following:

(8) Rebuilding Data
If one of the HDDs fails, the HDD LED will be o and the sounder
will annunciate. Press the SET button to stop the sound.
A new HDD can be installed and it will automatically rebuild with
data (if congured as RAID 1, 3, 5, 10).
1. Power down the RAID.
2. Remove the failed HDD.
3. Install the new HDD. The new HDD should be larger or equal to the
previous one. The use of identical HDDs from the same
manufacturer, with the same capacity and RPM is recommended.
4. Power up the RAID. The Red rebuild LED will blink to indicate a
rebuild in progress. The rebuild process can take up to 48 hours
depending on the size of the RAID array.
Notes:
• The rebuild operation will proceed regardless if the unit connected
or disconnected from the host computer.
• Do not change the HDD order when replacing drives.
Mac Users: Uncheck the option “Put Hard Disks to Sleep When
Possible” in the Energy Saver settings in System Preferences.
Windows 7/8 Users: Disable hard disk sleep in advanced power
settings: Control Panel > Power Options > Change Plan Settings >
Change Advanced Power Settings > Hard Disk >
Turn o hard disk after = Never.
If there is no HDD access for 30 minutes, the RAID will go to sleep
to save power. As soon as you access the drive, it will wake up.
NOTE: JBOD does not support auto sleep mode.
To prevent conflict with the OS sleep commands, we
recommend disabling hard drive sleep in your OS as follows:

6) Which drives are recommended for use with the Mobius?
For the best performance, recommended drives are:
WD Red, SE, RE or Hitachi Ultrastar.

(3) Inserting or Removing Drives
Inserting: Gently pull the lever and open the door. Insert/remove
drive into bay. To close, pull the lever and push the door all the way
closed. Release the lever when the door is closed.
Locking: Use the included key to lock the door if desired.

Supported Drives
Package Includes:
Mobius 5-Bay RAID, USB 3.0 cable, FireWire 800 cable,

(4) Setup
Perform a “Clear RAID”procedure after installing drives. This
applies to new or previously used drives.
Note: This procedure will not delete the partition or data from
previously used JBOD drives.
Clear RAID Procedure:
Set the switches on the back of the RAID unit to Clear RAID (all
switches down). Press and hold the SET button while turning on
the power. Hold the SET button until the 2nd beep occurs (approx.
10 seconds). Release the SET button. Any previous RAID mode is
removed and the drives are now set for JBOD mode. You may set a
new RAID mode, or leave in JBOD mode.
LEDs and Sound:
Normal = Blue Solid
Read/Write = Purple Blinking
Drive Error = LED O ; Sounder will beep (press SET to silence)
Rebuilding = Red Blinking
Note: The sounder will beep when the unit is powered up.

Press and hold SET button
and turn on the power.
Set the RAID switches to
the desired mode.
(JBOD)
When set to RAID 1 or RAID 10 mode RAID 1: Insert only 2 HDDs (Bay 1-2)
RAID 10: Insert 4 HDDs (Bay 1-4)
= Switch Position
Set RAID Mode:
After performing the Clear RAID procedure, set the switches on the
back of the Mobius to the desired mode. Press and hold the SET
button while turning on the power. Hold the SET button until the
2nd beep occurs (approx. 10 seconds). Release the SET button.
The RAID mode is now congured.
RAID 0 (Striping) is a non-redundant data mapping technique. It
combines data evenly across multiple drives simultaneously, dramatically
increasing performance.
• In Striping mode, it will be viewed as one single storage unit. If one disk
in the RAID System fails, all data in installed disks will be lost.
• The total capacity = smallest drive X the total number of drives. For
example, if the smallest drive is 1TB, the capacity will be 5 TB when 5
drives are installed.
RAID 1 (Mirroring) consists of two drives storing duplicate copies of the
same data. In this mode, the data is simultaneously written to two disks.
The speed of operation is slow in comparison to other RAID modes.
• Only 2 HDDs (bay 1 and 2) are allowed for the function to perform
properly.
RAID 3 or RAID 5 use block-level striping with parity data distributed
across all disks (RAID 5) or one disk (RAID 3). RAID 5 is the most common
mode due to the combination of redundancy and speed.
• 3 or more drives are required. If hotspare is desired, insert 3 or 4 drives
and create the RAID. Then insert a 4th or 5th drive(s) in bay 4 and/or 5 to be
used as a hotspare.When a drive fails, the spare drive will automatically be
rebuilt to replace the failed drive.
• The total capacity = all disks minus 1.The capacity is limited by the size
of the smallest disk. For example, if three 2 TB and two 3TB drives are
installed, the total capacity will be 8 TB ((2 TB x 5 disks) - 1 disk).
RAID 10 combines RAID 0 and RAID 1 in one single system. It creates two
sets of striped disks and then mirrors these sets.
• Only 4 HDDs are allowed for the function to perform. If 5 HDDs are
inserted, the 5th drive will be used as a hotspare. When a drive fails, the
5th drive will automatically be rebuilt to replace the failed drive.
Combine (Span) combines multiple hard drives into a single logical
unit. Unlike Striping, it writes data to the rst drive until it reaches full
capacity. When the rst disk reaches full capacity, data is written to the
second disk. Spanning provides the maximum possible storage capacity,
but does not increase performance or safety.
JBOD (Clear RAID) is not actually a RAID. It simply is a collection of
drives that are recognized as separate drives by the OS. JBOD provides no
performance increase or redundancy. This is the default setting.
We recommend using only enterprise or NAS drives. Drives such as
WD Green, Blue, Black, and Seagate Barracuda are not recommended
and may inhibit performance & limit technical support.
