Qsan XCubeNAS XN5004T NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from XCubeNAS XN5004T.

How to recover data from NAS Qsan XCubeNAS XN5004T

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

Can the use of specific data recovery software or services impact the success rate of data retrieval from NAS Qsan XCubeNAS XN5004T devices?

Yes, the use of specific data recovery software or services can impact the success rate of data retrieval from NAS Qsan XCubeNAS XN5004T devices. The success of data recovery depends on various factors such as the cause of data loss, the extent of damage to the device, and the effectiveness of the recovery software or service used.

Using reliable and professional data recovery software or services specifically designed for NAS devices can significantly increase the chances of successful data retrieval. These specialized tools are equipped with advanced algorithms and techniques to handle NAS-specific file systems and storage architectures.

However, it is important to note that not all data recovery software or services are created equal. Some may have better compatibility, features, or expertise in dealing with specific NAS devices like the Qsan XCubeNAS XN5004T. It is advisable to research and choose a reputable and experienced data recovery provider or software that has a track record of successfully recovering data from similar NAS devices.

Additionally, it is crucial to follow proper procedures and precautions during the data recovery process to avoid further damage or data loss. If in doubt, it is recommended to consult with professionals or seek expert assistance for the best possible outcome.

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

Although NAS XCubeNAS XN5004T 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 Qsan XCubeNAS XN5004T network-attached storage keeps SANOS 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.

      To recover data from a Qsan XCubeNAS XN5004T, you can follow these steps:

      1. Check the NAS status: Ensure that the NAS is powered on and connected to the network. Make sure that the hard drives are properly inserted and functioning.
      2. Access the NAS interface: Open a web browser and enter the IP address of the NAS to access the management interface. Login with your admin credentials.
      3. Check hard drive status: In the NAS interface, navigate to the "Storage" section and check the status of the hard drives. Ensure that all drives are recognized and healthy. If any drive is marked as failed or degraded, you may need to replace it before proceeding.
      4. Configure RAID settings: If you have a RAID setup, ensure that the RAID configuration is intact. If the RAID has been degraded or deleted, you may need to recreate it. Refer to the NAS user manual or Qsan support for detailed instructions on configuring RAID.
      5. Enable data recovery mode: Some NAS systems have a data recovery mode that allows you to access the data even if the file system is damaged. Check the NAS documentation or contact Qsan support to see if this feature is available for your model.
      6. Use data recovery software: If the above steps do not help or if the data is deleted or corrupted, you can use data recovery software to scan the NAS drives and recover the lost data. There are several data recovery software options available, such as EaseUS Data Recovery Wizard, Recuva, or Disk Drill. Install the software on a separate computer and connect the NAS drives to that computer either directly or via a USB adapter.
      7. Follow the software instructions: Launch the data recovery software and follow the instructions provided. Typically, you will need to select the NAS drives, choose a scan mode (quick scan or deep scan), and start the scanning process. The software will search for deleted or lost files and display the recoverable data.
      8. Recover the data: Once the scan is complete, preview the recovered files and select the ones you want to recover. Choose a location on a different drive or external storage to save the recovered files. Avoid saving them back to the NAS drives to prevent overwriting any existing data.

      Note: If you are not comfortable performing the data recovery process yourself, it is recommended to seek professional assistance from a data recovery service. They have specialized tools and expertise to handle complex data recovery scenarios.
