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 Digiever 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.

Are there any compatibility issues that can result in data loss for NAS Digiever DS-8456-SRM Pro+ devices?

There can be various compatibility issues that may result in data loss for NAS Digiever DS-8456-SRM Pro+ devices. Some potential issues include:

  1. Incompatible hard drives: Using incompatible or unsupported hard drives in the NAS device can lead to data loss. It is important to ensure that the hard drives are compatible with the NAS model and have been tested and approved by Digiever.
  2. Firmware compatibility: Outdated or incompatible firmware versions can cause issues with the NAS device, potentially leading to data loss. It is important to keep the firmware up to date and ensure compatibility with the device.
  3. Network compatibility: If there are any network compatibility issues, such as incompatible network switches or routers, it can result in data loss or connectivity problems with the NAS device. Ensuring proper network compatibility is crucial for the smooth operation of the NAS.
  4. Power supply issues: Inadequate or unstable power supply can cause data loss or damage to the NAS device. It is important to use a stable power source and consider using a UPS (Uninterruptible Power Supply) to protect against power fluctuations or outages.
  5. Software compatibility: Incompatible or unsupported software applications or operating systems used to access the NAS can lead to data loss or corruption. It is important to ensure that the software being used is compatible with the NAS device.

To minimize the risk of data loss, it is recommended to regularly backup the data stored on the NAS device and follow best practices for NAS maintenance and configuration.

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

Although the NAS DS-8456-SRM Pro+ 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 Digiever DS-8456-SRM Pro+ 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.
