3. Hardware Requirements and Precautions
1. After the hard disk is formatted, the actual total capacity of the MR2-B31 detected by the computer
operating system will vary from the sum of all hard disk capacities stated by the manufacturer.
2. To prevent data loss, do not remove MR2-B31 while the system is running.
3. Please always connect the USB cable to the computer to ensure the energy saving function
operating normally.
4. Once the system has been initialized, do not switch hard disks around during use. Doing so may
prevent the RAID from being recognized by the system.
5. Once RAID mode has been set up, the switching of hard drives will lead to the removal of data
from the hard disks. Please be sure to backup the data on the hard disk before making any
switches.
6. Before switching the RAID mode, you need to switch to JBOD before adjusting to the required
mode.
7. The product needs to be restarted after adding or changing the RAID mode, and the update is
guaranteed to be the new RAID mode.
8. If the MR2-B31 needs to be shut down or disconnected, please ensure the HDD is safely removed
through your operating system before turning off the power.
9. We strongly recommend backing up important data stored on the MR2-B31 to another storage
device or a remote site. STARDOM will not be held liable for the damage or loss of data you
stored on the MR2-B31.

5. RAID Mode Setting
Provide a big storage capacity and the data transfer efficiency, but no data porotection
feature.
Because of this Mirroring feature, your two HDDs/SSDs will keep an identical data after
your wtiting works. In case one of the two HDDs/SSDs is defect, MR2-B31 would still work
ne with only one of them. And once inserting a good HDD/SSD as the defect replacement,
it will do the rebuilding work by itself.
With JBOD mode, you could actually use the two HDDs/SSDs as the normal two storages
for your large memory capacity requirement, but no data porotection feature.
You could enjoy a double memory capacity from this BIG feature, but no data porotection
feature.

RAID 1RAID 0 BIG JBOD
5. RAID 模式切換設定
RAID 0：一個大的獨立資料儲存容量，並可加速資料存取但無資料保護功能。
RAID 1：兩顆硬碟是鏡射關係因此擁有相同的資料，因此有一顆硬碟損毀仍然可以正常運作。
當放⼊入新硬碟取代損毀硬碟後，系統會自自動將資料重建到新的硬碟。
JBOD ：可對兩顆獨立硬碟進行管理的工作，能大幅增加硬碟管理上的便利性，但無資料保護功能。
BIG ：兩顆硬碟的容量會被加總成一個大儲存容量，但無資料保護功能。
（
預設
）
切換 RAID 設定的標準程序：
1. 請在 MR2-B31 連線到電腦後，一併打開電腦和 MR2-B31 的電源開關。
2. 在硬碟讀取燈的藍燈恆亮時，將在 MR2-B31 背板上設定 RAID 的「切換開關」調至 JBOD。
3. 使用頂針插入「重置鍵」，待硬碟讀取燈上的藍紫燈結束閃爍，並轉成恆亮藍燈後鬆開頂針。
4. 在硬碟讀取燈的藍燈恆亮時，將在 MR2-B31 背板上設定 RAID 的「切換開關」調到你所要的設定
位置。
5. 使用頂針插入「重置鍵」，待硬碟讀取燈上的藍紫燈結束閃爍，並轉成恆亮藍燈後鬆開頂針。
6. 請您再做一次關、開 MR2-B31 電源的動作後，您已經改變、並重新設定了 MR2-B31 的 RAID。
