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.

Can the use of redundant power supplies reduce the chances of data loss on NAS Idis DR-6308P-SA devices?

Yes, the use of redundant power supplies can reduce the chances of data loss on NAS Idis DR-6308P-SA devices. Redundant power supplies provide a backup power source in case one power supply fails, ensuring uninterrupted power supply to the device. This can help prevent sudden power outages or fluctuations that could lead to data loss or corruption. By having redundant power supplies, the NAS device remains operational even if one power supply fails, reducing the risk of data loss.

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

Although the NAS DR-6308P-SA 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-6308P-SA 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.

  • Are there any specific security measures or encryption protocols implemented in the NAS Idis DR-6308P-SA to ensure secure network communication?

    According to the available information, the NAS Idis DR-6308P-SA is a network video recorder (NVR) rather than a network-attached storage (NAS) device. However, it is important to note that specific security measures and encryption protocols can vary depending on the firmware version and configuration of the device.

    That being said, Idis, the manufacturer of the DR-6308P-SA, typically implements several security measures in their NVRs. Some of these measures may include:

    1. User Authentication: The NVR may require users to authenticate themselves with a username and password before accessing the system.
    2. Secure Communication: The NVR may support encrypted communication protocols such as HTTPS (HTTP over SSL/TLS) to ensure secure data transmission between the device and clients.
    3. User Access Control: The NVR may provide granular user access control, allowing administrators to define different user roles and permissions to restrict access to specific functionalities or video streams.
    4. Network Security: The NVR may support network security features like IP filtering, which allows administrators to restrict access to the device based on IP addresses or ranges.
    5. Firmware Updates: Regular firmware updates are crucial to address security vulnerabilities and improve the overall security of the NVR. It is recommended to keep the firmware up to date to benefit from the latest security enhancements.

    It is always advisable to consult the product documentation, user manual, or contact the manufacturer directly for the most accurate and up-to-date information regarding the security measures and encryption protocols implemented in a specific device model.
