9. FAQ (Frequently Asked Questions)
1: In RAID 1 MODE, if a hard disk fails, is it possible for the
device to rebuild the data after replacing it with a new hard
disk?
Answer:
Yes, the device automatically starts rebuilding (rebuild)
after a new hard disk is installed. No additional settings or
configurations are required. To start the data recovery in RAID
1 mode, please proceed as follows:
- Turn off the device and remove the defective/corrupted hard
disk.
- Install a factory new hard disk into the empty bay.
- Turn on your PC. Connect the USB 3.1 cable first to the PC
and only then to the FANTEC mobiRAID X2U31.
- After a few seconds, both status LEDs will start flashing,
indicating that the recovery process has begun.
- The speed of the rebuild is about 250GB/h, i.e. with a hard
disk of 500GB the rebuild would take about 2h minimum, or
maybe more.
- When both status LEDs are solid blue, the recovery has been
completed successfully.
4: How can I backup my data if the FANTEC mobiRAID X2U31
itself fails?
Answer: If you are using the FANTEC mobiRAID X2U31 in JBOD
or RAID 1 mode, you can simply remove the hard drives from
the enclosure and install them in another external enclosure
or connect them directly to the internal interface in the PC to
access the data. For example, you can plug the hard drives into
a USB docking station and then back up the data.
If your device is operating in RAID 0 mode, you will need to
replace the FANTEC mobiRAID X2U31 with a new one yourself.
To do this, remove the hard drives and mark them with the
supplied DISK 1 and DISK 2 labels if you have not already done
so, to avoid confusion later when you put them back into a new
enclosure.
After your device has been replaced, please connect the
new (repaired) FANTEC mobiRAID X2U31 without hard disks
(empty) to a running PC using a USB 3.1 cable. Then set the
dip switches to RAID 0 mode. Now press the reset button
for about 10 seconds and then disconnect the USB 3.1
cable from the case again. Now place the hard disks into the
corresponding trays DISK1 and DISK2 and reconnect the USB
3.1 cable to the PC. Now you should be able to access your
data again without data loss.
5: What is the cause when my PC does not recognize the
FANTEC mobiRAID X2U31?
Answer: a) Please check if your USB 3.1 driver or firmware is up
to date, otherwise please try to update it.
b) Your hard disk(s) might need too much power. Please
connect the additional supplied USB cable to the DC-IN jack
on the device and to a free USB port on your PC.

Important note
- In order to recover your data as safely as possible, we
recommend that the new hard disk is also from the same
manufacturer and has the same model number, or at
least a factory-new hard disk with a larger capacity than
the defective hard disk.
- Do not disconnect the USB cable during the recovery
process.
2: Can I copy data to the hard disk during RAID 1 recovery?
Answer:
Yes, but it is not recommended and it will also increase
the duration of the recovery.
3: In RAID 1 mode, if one hard drive fails due to a defect, can I
still access the data on the other hard drive?
Answer: Yes, the PC can still access the data on the working
hard disk. If you want to be absolutely sure, you can save the
data of the hard disk elsewhere and only then start the RAID 1
recovery process.
