Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like WD also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can the NAS WD My Book Live Duo device's CPU or processing power affect data transfer and potential loss?

The CPU or processing power of the NAS WD My Book Live Duo device can affect data transfer and potential data loss in the following ways:

  1. Data Transfer Speed: The CPU is responsible for handling the data transfer process. A more powerful CPU can handle data transfer requests more efficiently, resulting in faster transfer speeds. Conversely, a slower CPU may struggle to process multiple transfer requests simultaneously, leading to slower data transfer speeds.
  2. Network Performance: The CPU also plays a role in managing network connections and protocols. A powerful CPU can handle multiple network connections and maintain stable network performance, ensuring smooth data transfer. In contrast, a weaker CPU may struggle to handle network traffic, leading to network congestion and slower transfer speeds.
  3. Data Loss Risk: During data transfer, the CPU is responsible for error checking and ensuring data integrity. A more powerful CPU can perform these tasks more effectively, reducing the risk of data corruption or loss during transfer. Inadequate processing power may result in errors or incomplete transfers, potentially leading to data loss or corruption.
  4. RAID Rebuild Time: The WD My Book Live Duo supports RAID configurations for data redundancy. In the event of a drive failure, the CPU is responsible for rebuilding the RAID array by redistributing data across the remaining drives. A more powerful CPU can perform this task faster, minimizing the time when the system is vulnerable to data loss. A slower CPU may take longer to rebuild the RAID, increasing the risk of data loss during this process.

Overall, a more powerful CPU in the NAS WD My Book Live Duo device can enhance data transfer speeds, reduce the risk of data loss or corruption, and expedite RAID rebuild times, providing a more reliable and efficient data storage solution.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS My Book Live Duo can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The WD My Book Live Duo network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

      Yes, there are specific recovery methods for NAS WD My Book Live Duo devices with striped or mirrored data configurations.

      For striped (RAID 0) configurations:

      1. Identify the failed drive by checking the status LEDs on the device or through the device's web interface.
      2. Replace the failed drive with a new one of the same capacity and model.
      3. Follow the device's documentation or user manual to rebuild the RAID array using the RAID management software or web interface.

      Note: In striped configurations, data is split across multiple drives, so if more than one drive fails, data loss may occur. It is recommended to regularly backup your data to avoid complete loss.

      For mirrored (RAID 1) configurations:

      1. Identify the failed drive by checking the status LEDs on the device or through the device's web interface.
      2. Remove the failed drive from the device.
      3. Replace the failed drive with a new one of the same capacity and model.
      4. The device should automatically rebuild the RAID array using the remaining drive and the new drive.

      Note: In mirrored configurations, data is duplicated across multiple drives, providing redundancy. If one drive fails, the other drive can still provide access to the data. However, it is recommended to replace the failed drive as soon as possible to restore redundancy and ensure data protection.

      It is always advisable to refer to the specific documentation or user manual provided by Western Digital for detailed instructions on recovering striped or mirrored configurations on the My Book Live Duo device.
