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