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 D-Link 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.

There are several risks of data loss due to firmware or software malfunctions in NAS D-Link DNS-1200-05 devices:

  1. Incomplete or failed firmware updates: If a firmware update is interrupted or fails to install properly, it can result in the NAS device becoming unresponsive or unstable. This can lead to data corruption or loss.
  2. Software bugs or glitches: NAS devices rely on complex software systems to manage data storage and retrieval. If there are bugs or glitches in the software, it can cause data corruption, file system errors, or even complete data loss.
  3. Hardware compatibility issues: Firmware updates or software upgrades may not be fully compatible with the hardware components of the NAS device. This can result in malfunctioning or unstable behavior, leading to potential data loss.
  4. Security vulnerabilities: Firmware or software malfunctions can expose the NAS device to security vulnerabilities, making it susceptible to unauthorized access, data breaches, or malware attacks. These security incidents can lead to data loss or compromise.
  5. User errors: NAS devices typically have complex configurations and settings that need to be properly managed by users. If users make mistakes while configuring or managing the device, it can result in data loss or accidental deletion of important files.
  6. Power outages or hardware failures during operations: Firmware or software malfunctions can increase the risk of power outages or hardware failures during critical operations, such as data transfers or disk synchronization. These events can cause data loss or corruption.

It is important to regularly update the firmware of NAS devices, follow best practices for data backup and redundancy, and implement appropriate security measures to minimize the risks of data loss due to firmware or software malfunctions.

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