How to recover data from Qsan XCubeNAS XN5012R 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 XCubeNAS XN5012R

Qsan XCubeNAS XN5012R 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 XN5012R.

How to recover data from NAS Qsan XCubeNAS XN5012R

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 a failed RAID rebuild process lead to data loss on NAS Qsan XCubeNAS XN5012R devices?

Yes, a failed RAID rebuild process can potentially lead to data loss on NAS Qsan XCubeNAS XN5012R devices. During a RAID rebuild, the system is reconstructing data from the remaining drives in the array onto a new or replaced drive. If the rebuild process is interrupted or encounters errors, it can result in data corruption or loss.

It is essential to ensure that the RAID rebuild process is performed correctly and that the system is stable during the process. This includes verifying the integrity of the drives, ensuring adequate power supply, and monitoring for any errors or warnings. Additionally, having a backup of the data is always recommended to mitigate the risk of data loss in case of any unforeseen issues during the rebuild process.

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

Although NAS XCubeNAS XN5012R 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 XCubeNAS XN5012R. 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.

How to recover data from a Qsan

XCubeNAS XN5012R has 12 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 XCubeNAS XN5012R 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.

      Yes, it is possible to recover data from a NAS Qsan XCubeNAS XN5012R device that has been affected by a sudden power outage or blackout. However, the success of data recovery depends on the extent of the damage caused by the power outage.

      Here are a few steps you can take to attempt data recovery:

      1. Power off the NAS device: After a power outage, it is important to turn off the NAS device immediately to prevent further damage.
      2. Check the power supply: Ensure that the power supply to the NAS device is stable and properly connected. Faulty power supply units can cause data corruption or loss.
      3. Restart the NAS device: Once the power supply is stable, you can try restarting the NAS device. In some cases, the NAS may automatically perform a file system check and repair any errors.
      4. Check the hard drives: If the NAS device does not boot up or if there are issues accessing the data, you may need to check the hard drives for any physical damage. Ensure that the hard drives are properly connected and functioning.
      5. Seek professional help: If the above steps do not resolve the issue, it is recommended to seek professional data recovery services. Data recovery experts have specialized tools and techniques to recover data from damaged NAS devices.

      It is important to note that attempting DIY data recovery methods without proper knowledge and experience may further damage the NAS device or result in permanent data loss. Therefore, it is always advisable to consult with a professional data recovery service for the best chances of successful data retrieval.
