How to recover data from NAS Level One GNS-2000

Level One GNS-2000 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from GNS-2000.

How to recover data from NAS Level One GNS-2000

Recover data from damaged RAID arrays inaccessible from a computer.

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 Level One also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Are there any limitations or restrictions on file or folder names that can cause potential data loss on NAS Level One GNS-2000 devices?

There are certain limitations and restrictions on file and folder names that can potentially cause data loss on NAS Level One GNS-2000 devices. These limitations may vary depending on the specific firmware version and configuration of the device. Some common limitations and restrictions include:

  1. Length Limitations: The file or folder name length may be limited to a certain number of characters, typically 255 characters. If a file or folder name exceeds this limit, it may cause issues and potential data loss.
  2. Character Restrictions: Certain special characters may not be allowed in file or folder names, such as slashes (/), backslashes (), colons (:), question marks (?), asterisks (*), quotation marks ("), less than (<), greater than (>), and vertical bars (|). Using these restricted characters in file or folder names can lead to data loss.
  3. Case Sensitivity: Some NAS devices, including Level One GNS-2000, are case-sensitive when it comes to file and folder names. This means that "file.txt" and "File.txt" would be treated as two separate files. Failure to adhere to the correct case sensitivity can result in data loss or confusion.
  4. Reserved Names: Certain names may be reserved for system use and cannot be used for files or folders. These reserved names can vary depending on the NAS device and its operating system. Attempting to use reserved names can lead to data loss or system instability.

It is important to consult the device's documentation or contact the manufacturer for specific limitations and restrictions on file and folder names to avoid potential data loss on NAS Level One GNS-2000 devices.

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

Although NAS GNS-2000 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.

      It is possible to recover data from a physically damaged NAS Level One GNS-2000 device, but the success of the recovery process depends on the extent of the damage. If the damage is limited to the hardware components and the hard drives are still intact, it may be possible to recover the data by transferring the drives to a compatible NAS device or using data recovery services.

      However, if the damage extends to the hard drives themselves, such as physical platter damage or severe electronic failure, the chances of data recovery may be significantly reduced. In such cases, it is recommended to consult with professional data recovery services who specialize in handling physically damaged storage devices. They have the necessary tools and expertise to recover data from such situations, although the success and cost of the recovery may vary.

  • How does the process of adding an additional hard drive to the NAS Level One GNS-2000 affect the overall storage capacity and data management capabilities?

    Adding an additional hard drive to the NAS Level One GNS-2000 would typically increase the overall storage capacity and enhance data management capabilities. Here's how it affects each aspect:

    1. Storage Capacity: The additional hard drive increases the total amount of storage available on the NAS. For example, if the initial configuration had a single 1TB hard drive, adding another 1TB hard drive would double the total storage capacity to 2TB. This allows for storing more files, documents, media, and other data on the NAS.
    2. Redundancy and Data Protection: The NAS Level One GNS-2000 usually supports various RAID configurations. By adding an additional hard drive, you can set up RAID levels like RAID 1 (mirroring) or RAID 5 (striping with parity) to provide data redundancy and protection against drive failures. This means that even if one drive fails, the data remains accessible and can be rebuilt onto a replacement drive.
    3. Performance: Depending on the NAS model and its capabilities, adding an additional hard drive can improve read and write speeds. By configuring the NAS in RAID levels like RAID 0 (striping without redundancy), data can be distributed across multiple drives, leading to increased performance. However, it's important to note that RAID 0 does not provide data redundancy, so the risk of data loss due to a drive failure increases.
    4. Data Management: With an additional hard drive, you can utilize features like storage pooling and volume expansion. Storage pooling allows you to combine multiple drives into a single logical storage pool, simplifying storage management. Volume expansion enables you to extend existing volumes or create new ones, providing flexibility in organizing and managing data.

    Overall, adding an additional hard drive to the NAS Level One GNS-2000 expands storage capacity, enhances data protection, potentially improves performance, and provides more options for data management.
