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 QNAP 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 type of file system used on NAS QNAP Turbo Station TS-431P / TS-431P2 / TS-431P3 devices affect data loss risks?

Yes, the type of file system used on NAS QNAP Turbo Station TS-431P / TS-431P2 / TS-431P3 devices can affect data loss risks. The file system is responsible for organizing and managing data on the storage devices, and different file systems have varying levels of robustness and reliability.

Some file systems, such as NTFS (Windows) or ext4 (Linux), are known for their stability and data protection features. These file systems have built-in mechanisms to prevent data corruption and ensure data integrity. They also support features like journaling, which helps recover data in case of unexpected power loss or system crashes.

On the other hand, some file systems may have limitations or less robust data protection mechanisms. For example, FAT32, which is commonly used in older devices, does not provide advanced data protection features like journaling. It is more prone to data corruption and can result in data loss if not handled properly.

Therefore, choosing a reliable and robust file system for your NAS device is crucial in minimizing data loss risks. It is recommended to use file systems like NTFS or ext4 that provide better data protection features and have a proven track record of stability and reliability.

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

Although the NAS Turbo Station TS-431P / TS-431P2 / TS-431P3 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.
