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 Qsan 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.

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

Although the NAS XCubeNAS XN5012R 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.

Step-by-Step Data Recovery with Hetman RAID Recovery

Hetman Raid Recovery

This program restores data from damaged RAID arrays and is fully compatible with Qsan XCubeNAS XN5012R. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually 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.
