How to recover data from Qsan XCubeNXT XN8026D NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Qsan XCubeNXT XN8026D

Qsan XCubeNXT XN8026D NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from XCubeNXT XN8026D.

How to recover data from NAS Qsan XCubeNXT XN8026D

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.

Are there any known compatibility issues or limitations when connecting NAS Qsan XCubeNXT XN8026D devices to specific switches or routers?

There are no specific compatibility issues or limitations when connecting Qsan XCubeNXT XN8026D NAS devices to switches or routers. These devices use standard network protocols (such as TCP/IP, SMB, NFS) and support common networking technologies like Ethernet. As long as the switches or routers support these protocols and technologies, you should be able to connect the NAS devices without any issues.

However, it's always recommended to check the product documentation or contact the manufacturer for any specific requirements or recommendations regarding network connectivity. Additionally, ensure that the switches or routers have sufficient bandwidth, network ports, and configurations to handle the expected data traffic from the NAS devices.

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

Although NAS XCubeNXT XN8026D 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Qsan XCubeNXT XN8026D. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

XCubeNXT XN8026D has 26 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • RAID 50;
  • RAID 60;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

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 XCubeNXT XN8026D 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.

      Data recovery from a NAS device can be challenging if the device is not responding or freezing frequently. However, there are some steps you can take to try and recover your data:

      1. Check the network connection: Ensure that the network connection between your computer and the NAS device is stable. Try connecting the NAS directly to your computer using an Ethernet cable to rule out any network issues.
      2. Power cycle the NAS: Turn off the NAS device, unplug it from the power source, and wait for a few minutes. Then, plug it back in and power it on. Sometimes, a simple power cycle can resolve freezing or unresponsive issues.
      3. Update firmware: Check if there are any firmware updates available for your Qsan XCubeNXT XN8026D device. Updating the firmware can sometimes fix bugs and improve device performance.
      4. Try different access methods: If you are accessing the NAS device using a specific protocol (e.g., SMB, NFS), try accessing it using a different protocol to see if it improves responsiveness.
      5. Contact technical support: If none of the above steps work, it is recommended to contact Qsan technical support or consult with a professional data recovery service. They may have specific troubleshooting steps or tools to recover data from a non-responsive or frequently freezing NAS device.

      Remember, it is crucial not to attempt any advanced recovery methods without proper knowledge or expertise, as it may lead to permanent data loss.
