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 Digiever 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 malware or ransomware attacks lead to data loss in NAS Digiever MN-2105 Pro+ devices?

Yes, malware or ransomware attacks can potentially lead to data loss in NAS Digiever MN-2105 Pro+ devices. If a device is infected with malware or targeted by ransomware, the attackers can encrypt or delete the data stored on the NAS device, making it inaccessible to the user. It is essential to have proper security measures in place, including regular backups and strong security practices, to mitigate the risk of such attacks and protect the data stored on the NAS device.

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

Although the NAS MN-2105 Pro+ 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.

Step-by-Step Data Recovery with Hetman RAID Recovery

Hetman Raid Recovery

This program restores data from damaged RAID arrays and is fully compatible with Digiever MN-2105 Pro+. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

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 Digiever MN-2105 Pro+ 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.

    How does data recovery from NAS Digiever MN-2105 Pro+ differ from other storage devices?
    • Hetman Software
      Hetman Software 25.08.2023 00:59 #

      Data recovery from a NAS (Network Attached Storage) device like the Digiever MN-2105 Pro+ can differ from other storage devices in a few ways:

      1. RAID Configuration: NAS devices often use RAID (Redundant Array of Independent Disks) configurations for data redundancy and improved performance. The Digiever MN-2105 Pro+ supports various RAID levels like RAID 0, 1, 5, 6, 10, 50, 60, and JBOD. Data recovery from a NAS with RAID involves understanding and reconstructing the RAID array to recover the data, which can be more complex than recovering data from a single drive.
      2. Network Connectivity: NAS devices are designed to be accessed over a network, which means the data recovery process might involve troubleshooting network connectivity issues. It may require working with network administrators to ensure proper access to the NAS device for data recovery purposes.
      3. Proprietary Software: NAS devices often come with their own proprietary software or operating systems. The data recovery process may require familiarity with the specific software or OS used by the Digiever MN-2105 Pro+ to access and recover the data successfully.
      4. Remote Access: NAS devices allow remote access to stored data, which means data recovery can be performed remotely as well. This can be advantageous as it eliminates the need to physically access the device, but it also requires expertise in remote data recovery techniques.
      5. Specialized Tools: Data recovery from NAS devices may require specialized tools or software designed specifically for NAS recovery. These tools help in accessing and recovering data from the NAS device, considering its unique configuration and file system.

      Overall, data recovery from a NAS like the Digiever MN-2105 Pro+ may require additional expertise in RAID configurations, network troubleshooting, proprietary software, remote access techniques, and specialized tools compared to recovering data from other storage devices like hard drives or SSDs.
