Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Buffalo often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Can virtualization technologies impact data loss risks in NAS Buffalo LinkStation LS-CH2.0TL devices?

Yes, virtualization technologies can impact data loss risks in NAS Buffalo LinkStation LS-CH2.0TL devices. Virtualization allows for the creation of virtual machines (VMs) that can be used to isolate and protect data. By running the NAS device as a virtual machine, data loss risks can be minimized through various means:

  1. Snapshot and backup: Virtualization platforms often provide snapshot capabilities, allowing you to take point-in-time snapshots of the virtual machine. These snapshots can be used as backups, providing a way to restore data in case of accidental deletion or corruption.
  2. High availability: Virtualization technologies can enable high availability features, such as clustering or live migration, which allow for seamless failover in case of hardware or software failures. This can reduce the risk of data loss due to NAS device failures.
  3. Disaster recovery: Virtual machines can be replicated or moved to off-site locations, providing disaster recovery options. In the event of a catastrophic failure or site outage, the virtual machine running the NAS device can be quickly restored or brought up in a different location.
  4. Increased security: Virtualization technologies often provide advanced security features, such as virtual network segmentation and isolation, which can help protect the NAS device and its data from external threats.

However, it's important to note that while virtualization technologies can help mitigate data loss risks, they are not a guarantee. Proper backup strategies, regular testing, and adherence to best practices are still essential to ensure data protection and minimize the risk of data loss.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS LinkStation LS-CH2.0TL can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually Stored?

The Buffalo LinkStation LS-CH2.0TL 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.

    Are there any specific file systems used in NAS Buffalo LinkStation LS-CH2.0TL devices that may affect data recovery?
    • Hetman Software
      Hetman Software 30.08.2023 23:59 #

      The Buffalo LinkStation LS-CH2.0TL devices typically use the XFS file system for their internal drives. This file system is commonly used in Linux-based systems and offers high-performance and stability. However, it may affect data recovery in certain cases because XFS is a journaling file system, which means it keeps track of changes to the file system in a journal. If the journal becomes corrupted or damaged, it can make data recovery more challenging. Additionally, if the NAS device is using RAID configurations, the specific RAID level and settings can also impact data recovery. It is always recommended to consult a professional data recovery service if you encounter any data loss issues with your NAS device.
