degraded array. Failure to do so can result in the loss of data. To set up or change the RAID type,
disconnect all data cables and reboot ToughTech Duo. After the unit has initialized, the LCD will
display the drives' mode and status.
2.1 Creating a New RAID (use the LCD and interface buttons to complete this step)
(Follow these steps for setting up a new RAID if you did not purchase your unit
pre-configured.)
WARNING: Any data on the new disk will be destroyed when the drive is added to the RAID.
a. Upon insertion of new disks, the LCD will read "RAID Error: not a RAID set."
b. Press the Enter button twice.
c. The LCD screen will display "MAKE A NEW RAID?"
d. Select "YES."
e. Select your RAID type (RAID 0 or 1)
f. The LCD screen will display "Will erase all data OK?"
g. Select "YES." The RAID is now created.
2.2 Changing the RAID Type (use the LCD and interface buttons to complete this step)
a. Press the Up button, for the "Change RAID Mode" screen.
b. Press the Enter button.
c. Press the Down or Up button to select the desired RAID type. The screen will display
"Will erase all data OK?" (Ensure all data is backed up before continuing.) If data is
backed up press Enter.
d. The new configuration will be selected and ToughTech Duo will reboot.
e. ToughTech Duo has been configured and is ready for operation.
3. LCD Messages
Hard drive status is reported as OK, No Disk, Unused, or Failing.
• OK – Indicates that the hard drive is in use or ready to use.
• No Disk – Indicates that the hard was removed or not installed.
• Unused – A new drive was installed and not added to the RAID.
• Failing – Indicates the drive is malfunctioning. Possible causes of a failure message
include an inability to recognize the drive, a compatibility problem, or damaged sectors.
4. Adding a New Disk
4.1 RAID 1
In the event of a disk failure or removal for a RAID 1, the RAID will continue to function in a
degraded state. Add a new disk to ToughTech Duo to rebuild the RAID.
After the new drive has been detected ToughTech Duo will ask to add a new disk. Press
the Enter button to select "Yes" to add the disk. The disk will be added to the RAID and the
RAID will begin to rebuild. The LCD screen will display the percent complete for the rebuild.
Rebuild times vary; a 500GB hard drive takes just over 1.5 hours to rebuild.
4.2 RAID 0
Never remove a drive from a running RAID 0 as this will cause the loss of all data. In the
event of a disk failure for a RAID 0, the RAID will be destroyed. Add a drive and then press
the Up button to create a new RAID. Follow the display prompts to build a new array.
4.3 Single Disk Mode
In the event of a disk failure in single disk mode, all data will be lost. The single disk mode
allows usage of a single hard drive. If a second drive is added later, it cannot be combined
with the first disk, nor will it provide the option of two individual disks to be seen by the
host computer. It will allow the option to create a new RAID using both disks, though this
will destroy any data on both disks.
RAID is not a Backup
Because your ToughTech Duo features a redundant RAID mode which protects against a hard drive
mechanical failure, it is an excellent part of any backup strategy. However, a RAID is not, in itself,
a backup strategy. Many things besides hard drive failure can compromise your data (e.g. malware,
theft, fire, etc.) That's why it's important to have another copy of your data somewhere else. Follow
the 3-2-1 backup rule: your data should exist in three different places on two different storage media
and at least one of those copies should be maintained offsite.
If you do not have an effective backup strategy, you may not be able to recover your data, or the cost
of recovery may be quite expensive. Our warranty does not cover costs associated with data loss (nor
do the warranties of other hard drive manufacturers). We know it would be heartbreaking to lose your
data, so please plan accordingly!
