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.

Can device firmware rollback or downgrading impact data loss risks for NAS Digiever DS-8464-SRM Pro+ devices?

Rolling back or downgrading the firmware of a NAS device like the Digiever DS-8464-SRM Pro+ can potentially impact data loss risks. Here are a few considerations:

  1. Compatibility: Before attempting a firmware rollback, ensure that the older firmware version is compatible with your NAS device model. Using an incompatible firmware version can lead to system instability or malfunction, potentially resulting in data loss.
  2. Bug Fixes and Security Patches: Firmware updates often include bug fixes, performance improvements, and security patches. By rolling back to an older firmware version, you may lose these important updates, leaving your NAS device vulnerable to security threats or stability issues.
  3. Data Corruption: If the firmware rollback process is not executed correctly, it can lead to data corruption or loss. It is crucial to follow the manufacturer's instructions precisely and ensure that you have a backup of your important data before attempting any firmware changes.
  4. Unsupported Features: Newer firmware versions may introduce additional features or improvements that are not available in older versions. By downgrading the firmware, you may lose access to these features, impacting the functionality and usability of your NAS device.

To minimize the risks associated with firmware rollback, it is recommended to consult the manufacturer's documentation, seek support from their technical team, and backup all critical data before proceeding with any firmware changes.

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

Although the NAS DS-8464-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.
