Before use, power on the device and connect the data interface to your computer.
Procedure for creang or changing RAID:
For Mac users, disk array inialisaon and formang can be completed as below:
5. Connecon
6. RAID
Procedure for connecon:
Step 1: Connect one end of the USB Type-C cord to the Thunderbolt3 interface of this device, and connect the
other end to the USB interface of your computer.
Step 2: Please connect the device a power source by using the power adapter. The power adapter provides
12V DC;
Warning: do not use the non-original power adapter for this device. Otherwise, the device may malfuncon
and the physical body may be damaged in an extreme case!
Step 3: Press the power buon to power on. When the power is connected, the device’s power indicator will
turn on.
Step 4: If the hard drives work normally and the device powers on, the hard drive indicator will temporarily
display red, followed by Blinking orange, followed by Blinking green, and finally green lights. If the hard drive
indicator displays red all the me, it indicates that the hard drive is cannot be read. The hard drive may be
damaged, inccompable with the device. If this occurs, please turn off the device and proceed to reinstall the
same hard drive. If the hard drive indicator sll displays red, please replace the hard drive with a new one and
try again.
Step 5: Aer the device is connected to your computer, you might see a prompt asking you to format the
device or come across a message reading “The disk you inserted was not readable by this computer”. Please
select “Cancel” or “Ignore”, as the formang of the device should occur only aer you create a disk group.
Step 1: Connect this device to your computer through a USB type C cord, and power it on.
Step 2: Choose a RAID for the device (the factory default is SINGLE). To choose a RAID type, use a screwdriver
to rotate the rotary switch on the rear cover of this device to turn the pointer to the desired RAID type.
Step 3: Use a thimble to press and hold the RESET buon for 5s to let the newly set RAID take effect.
Step 4: Format RAID. Aer seng RAID, you need to inialize and format the RAID on your computer. The
procedure for inializaon and formang is the same for hard drive inializaon and formang. As for the
detailed procedure for hard drive inializaon and formang, please look it up online.
A. Go to GO > Applicaon Tool > Disk Ulity > External;
b. Locate an uninialized external disk in the menu (this will be the TerraMaster array);

Warning!
Creang or changing RAID may lead to formang of hard drives, and consequently all the data on the hard
drives will be deleted. Please back up the data in the hard drives beforehand.
Note:
While you are replacing the faulty hard drive, this device needs to remain powered on and connected to the
computer. The capacity of the new hard drive should be larger than or equal to that of the faulty hard drive.
The amount of me that data recovery takes depends on the capacity of the hard drive. It ranges from a few
hours to tens of hours. The device and the computer need to remain powered on during data recovery.
During the data recovery, the indicator of the newly inserted hard drive (referred to as the secondary disk)
flashes orange, and the indicator of the original drive flashes green.
If one of the hard drives becomes faulty while the device is in RAID 1, you can replace the faulty hard drive,
and data will be automacally recovered.
