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 Thecus 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.

Are there any known issues or limitations when using NAS Thecus N2810PLUS devices with virtualization platforms such as VMware or Hyper-V?

There are a few known issues and limitations when using Thecus N2810PLUS devices with virtualization platforms like VMware or Hyper-V. Some of these include:

  1. Limited hardware resources: The Thecus N2810PLUS is a low-end NAS device, so it may not have enough processing power, memory, or storage capacity to handle demanding virtualization workloads.
  2. Lack of official support: Thecus does not officially support virtualization platforms like VMware or Hyper-V on the N2810PLUS. This means that you may not be able to get technical assistance or firmware updates specifically tailored for virtualization.
  3. Limited virtualization features: The N2810PLUS may not support advanced virtualization features like live migration, high availability, or fault tolerance. These features are typically available on enterprise-grade NAS devices.
  4. Performance limitations: Due to the limited hardware resources, the performance of virtual machines running on the N2810PLUS may be lower compared to dedicated virtualization servers. This can impact the overall performance and responsiveness of your virtualized environment.
  5. Compatibility issues: There may be compatibility issues between the N2810PLUS and certain virtualization platforms or specific versions of hypervisors. It is recommended to check the compatibility matrix provided by the virtualization platform vendor before attempting to run virtual machines on the N2810PLUS.

It's important to note that these limitations may vary depending on the specific use case and workload requirements. It is always recommended to thoroughly test and evaluate the performance and compatibility of the N2810PLUS with your virtualization platform before deploying it in a production environment.

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

Although the NAS N2810PLUS 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.

      It is possible to recover data from a physically damaged NAS device, but it depends on the extent of the damage. If the power surge has caused damage to the internal components of the NAS, it may be difficult to recover the data. However, if only the power supply or other easily replaceable components are damaged, it may be possible to recover the data by repairing or replacing those components.

      In any case, it is recommended to contact a professional data recovery service that specializes in NAS devices. They will have the necessary expertise and tools to assess the damage and attempt data recovery if possible.
