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 Idis 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.

What are the risks of data loss due to firmware or software malfunctions in NAS Idis DR-6316PS-A devices?

There are several potential risks of data loss due to firmware or software malfunctions in NAS Idis DR-6316PS-A devices:

  1. Corrupted or inaccessible data: A firmware or software malfunction can lead to data corruption or make the data inaccessible. This can result in the loss of important files, documents, or other data stored on the device.
  2. System instability: Malfunctioning firmware or software can cause the NAS device to become unstable, leading to frequent crashes or system failures. This can disrupt normal operations and potentially result in data loss if data is being written or transferred at the time of the malfunction.
  3. Data integrity issues: If the firmware or software malfunctions during data transfer or writing processes, it can result in incomplete or partially written data. This can lead to data integrity issues, making the affected files unusable or corrupted.
  4. Data deletion or formatting: In some cases, a firmware or software malfunction can cause unintentional data deletion or formatting of the storage drives. This can result in the complete loss of data if proper backups are not in place.
  5. Difficulty in data recovery: If data loss occurs due to firmware or software malfunctions, the process of data recovery can become more challenging. Depending on the severity of the malfunction, it may require specialized expertise and tools to recover the lost data.

To mitigate these risks, it is important to regularly update the firmware and software of the NAS device to the latest versions provided by the manufacturer. Additionally, implementing a robust backup strategy, including offsite backups, can help minimize the impact of data loss in case of a malfunction.

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

Although the NAS DR-6316PS-A 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.

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 Idis DR-6316PS-A network-attached storage keeps OS Linux 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.

      It is possible to recover data from a NAS (Network Attached Storage) device like the Idis DR-6316PS-A, even if it is experiencing firmware update or installation problems. However, the process may vary depending on the specific issue and the capabilities of the device.

      Here are a few steps you can try to recover the data:

      1. Contact the manufacturer or technical support: If the device is under warranty or you have access to technical support, it is recommended to contact them first. They may provide guidance or solutions specific to your device.
      2. Power cycle the device: Disconnect the power source, wait for a few minutes, and then reconnect it. This simple step can sometimes resolve firmware or installation issues.
      3. Access the NAS through a different method: If the firmware update or installation problem is preventing you from accessing the NAS through the usual methods, try alternative methods. For example, if you usually access it through a network connection, try connecting a monitor and keyboard directly to the device to see if you can access its interface.
      4. Factory reset: If all else fails and you have exhausted other options, you may need to perform a factory reset. This will restore the device to its original settings, but it will also erase all data stored on the NAS. Make sure to back up your data before attempting a factory reset.
      5. Data recovery services: If the above steps do not work or you are not comfortable performing them, you can consider professional data recovery services. These services specialize in recovering data from various storage devices, including NAS devices. They have specialized tools and techniques to recover data even from devices with firmware or installation problems.

      Remember to always consult the manufacturer's documentation or seek professional help if you are unsure about any steps involved in recovering data from your NAS device.
