(9) Troubleshooting and FAQ
After setting a new RAID mode, you must format the volume
before it is accessible.
1. Connect the RAID to the computer.
2. Congure the desired mode as explained in section 4.
3. After the RAID is congured, use Disk Management on the PC
or Disk Utility on the Mac to format the volume *.
* 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:

(7) Auto Sleep Mode
If there is no HDD access for 20 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:
Mac Users: Uncheck the option “Put Hard Disks to Sleep When
Possible” in the Energy Saver settings in System Preferences.
Windows Users: Disable hard disk sleep and USB suspend in
advanced power settings:
Control Panel > Power Options > Change Plan Settings > Change Advanced
Power Settings > Hard Disk > Turn o hard disk after = Never.
Control Panel > Power Options > Change Plan Settings > Change Advanced
Power Settings > USB Settings > USB Selective Suspend = Disabled.
(8) Rebuilding Data
If one of the HDDs fails, the HDD LED will be red/purple and the
sounder will beep. Press the SET button to stop the sound.
A new HDD can be installed and it will automatically rebuild with
data (if congured as RAID 1, 3, 5, 10).
1. Power down the Mobius & disconnect it from the computer.
2. Remove the failed HDD.
3. Install a new unformatted HDD. The new HDD should be larger
or equal to the previous one. The use of identical HDDs from the
same manufacturer is recommended.
4. Power up the RAID. The LED will slowly blink red/purple 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 replacement drive must be a new, unformatted drive.
• We recommend disconnecting the Mobius from the host computer
during the rebuild process.
• Do not change the HDD order when replacing drives.
1) If the system experiences an HDD failure:
The LED for the HDD will be solid red/purple 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) or JBOD. In the
other modes, you cannot remove a single drive and access it
outside of the RAID.
3) The Mobius is going to sleep. How can I prevent this?
Please visit Section 7 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 mins.
4) 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.
5) Which drives are recommended for use with the Mobius?
We recommend using only enterprise or NAS drives such as
WD Red, WD SE/RE. We DO NOT recommend WD Green, Blue,
Black, and Seagate Barracuda. Use of these drives may inhibit
performance & limit technical support.
6) Can I lay the Mobius on its side?
No. The Mobius is not designed to be placed on its side, and it
will not function properly in this position.
7) The Mobius is connected to a Mac Yosemite computer via
FW800. The Mobius appears in Disk Utility, but I am unable to
format the drive(s). Why?
The issue may be caused by the Yosemite FireWire driver. Please
disconnect from FW800 and connect using USB to format the
drive(s). After completion, reconnect via FW800 to access the
formatted volume(s).

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
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.
(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.
Set the RAID switches to
the desired mode.

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 3 TB 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.
