(9) Troubleshooting and FAQ
1) Does a "Clear" procedure delete data from existing RAID 1 or
JBOD drive(s)?
No, if a Clear procedure is performed on RAID 1 or JBOD drives, the
existing data on the drives will not be deleted.
2) Can I remove a drive from the RAID and install it in another
enclosure for access to the les?
Yes, only if using RAID 1(Mirroring) or JBOD.
3) 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).
(7) Sleep Mode
(8) RAID 1 Rebuild
If one of the drives fail, the drive’s LED will change from BLUE to
RED when connected to a computer. A new HDD can be installed
and will automatically rebuild with data (if congured for RAID 1).
Note: The replacement drive must be a new, unformatted drive
with the same capacity as the original.
1. Power down the Mobius.
2. Remove the failed drive.
3. Install the new drive and power up the Mobius.
4. The LEDs will blink twice per second, which indicates a
rebuild in progress. This can take several hours.
The Mobius 2-Bay does not have an auto-sleep timer. However,
it will follow the sleep settings of the computer. When your computer
enters sleep mode, the drives inside the Mobius will spin down.

Press and hold MODE button
and turn on the power.
Set the RAID switch to
the desired mode.
The default mode is JBOD. To set a new mode, perform these steps:
Set RAID Procedure:
1. Set the switch on the Mobius to the desired mode.
2. Connect the Mobius to the host computer.
3. Press & hold the MODE button while turning on the power.
4. Continue holding the MODE button for 7-10 seconds.
5. Release the MODE button. The RAID mode is now congured.
If changing RAID modes, you rst must perform a “Clear” procedure
to remove the previous RAID mode.
Clear Procedure:
1. Set the switch on the Mobius to JBOD.
2. Connect the Mobius to the host computer.
3. Press the MODE button while turning on the power.
4. Hold the MODE button for 7-10 seconds.
5. Release the MODE button. Any previous RAID mode is removed
and the drives are now set for JBOD mode.
RAID 0 (Striping) is a non-redundant data mapping technique. It
combines data evenly across both drives simultaneously; dramatically
increasing performance.
• RAID 0 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 500GB and the other is 2TB, the total
capacity will be 1TB (500 x 2).
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 RAID 0.
JBOD (Clear) is 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.
Combine (Span) combines both 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 does not increase performance or safety.

(6) Formatting
After setting a new RAID mode, you must format the volume
before it is accessible.
To format using Windows:
http://oyendigital.com/windows-reformat.html
To format using MAC OS:
http://oyendigital.com/mac-reformat.html
Note: The drive can be used on both Windows and Mac
systems by formatting the drive as“MS-DOS (FAT32)” or
“exFAT.” Instructions are provided in the Mac OS link above.
If using RAID 0 we recommend performing a low level
format after setting the RAID. Please refer to the following:
