Configuring RAID 1 Mirroring on the WD My Book Live Duo The WD My Book Live Duo is a dual-drive network-attached storage (NAS) system designed for home and small office backups. By default, it often ships in a spanned configuration (RAID 0), which combines both drives into one large storage pool. However, this offers zero data protection; if one drive fails, you lose everything.
Switching to RAID 1 (Mirroring) creates an exact copy of your data on both drives. If one hard drive fails, your data remains safe and accessible on the second drive.
Here is the step-by-step guide to configuring RAID 1 on your device. Important Prerequisites
Data Backup: Changing the RAID configuration will destroy all existing data on the device. Back up all your files to another location before proceeding.
Network Connectivity: Ensure your computer and the WD My Book Live Duo are connected to the same local network via an Ethernet cable for stability. Step 1: Access the Dashboard
Open your preferred web browser on a computer connected to the same network. Enter the device URL in the address bar: Windows: http://mybookliveduo Mac: http://mybookliveduo.local
Alternative: Enter the static IP address assigned to your NAS (e.g., 192.168.1.50). Enter your administrator password if prompted. Step 2: Navigate to Storage Settings Once the dashboard loads, locate the main navigation menu. Click on the Settings gear icon. Select the Storage tab from the left-hand or top sub-menu.
Click on Drive Management (or RAID depending on your firmware version). Step 3: Change the RAID Mode
Look for the section labeled Current Configuration. It will likely display Spanned (RAID 0) or JBOD. Click the Change Mode (or Configure) button.
A configuration wizard window will appear. Select Mirror (RAID 1) from the available options.
The system will display a warning noting that the capacity will be cut in half (e.g., an 8TB unit becomes a 4TB protected unit) and that all data will be erased. Click Next or Confirm. Step 4: Formatting and Initialization
Type in the administrator password or check the confirmation box to authorize the data wipe. Click Submit or Finish to start the process.
The NAS will begin formatting the drives and rebuilding the internal file system structure into a mirrored array. Step 5: Verify the Setup
Do not disconnect the power or ethernet cable during the format process, which may take several minutes. Once complete, the dashboard will refresh. Return to the Storage > Drive Management section.
Verify that the Volume Status reads Healthy and the Current Configuration displays Mirror (RAID 1). What to Expect Next
Your total available storage space will now be equal to the size of a single drive inside the unit. The internal system will handle all future mirroring automatically. When you write a file to the network share, the WD My Book Live Duo duplicates it across both physical disks in real-time, giving you peace of mind against drive hardware failure.
