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.

Are there any compatibility issues or limitations when connecting NAS QNAP Turbo Station TS-2477XU-RP devices to different operating systems or platforms?

When connecting a QNAP Turbo Station TS-2477XU-RP NAS device to different operating systems or platforms, there can be some compatibility issues or limitations. Here are a few things to consider:

  1. File System Compatibility: The QNAP Turbo Station supports various file systems like NTFS, FAT32, HFS+, and exFAT. However, some file systems may have limitations or may not be fully supported on certain operating systems or platforms. For example, NTFS can be read-only on macOS without additional software.
  2. Network Protocols: The QNAP Turbo Station supports multiple network protocols such as SMB/CIFS, AFP, NFS, and FTP. While these protocols are widely supported, some older operating systems or platforms may have limited support for certain protocols. It's essential to ensure that the operating system or platform you are using supports the network protocol you intend to use.
  3. Software Compatibility: QNAP provides various software applications and utilities to enhance the functionality of their NAS devices. These applications may have specific system requirements and may not be available for all operating systems or platforms. It's important to check the compatibility of the desired software with your operating system or platform.
  4. Firmware Updates: QNAP regularly releases firmware updates for their NAS devices, which can introduce new features, bug fixes, and compatibility improvements. It's recommended to keep the NAS firmware up to date to ensure better compatibility with different operating systems or platforms.
  5. Third-Party Applications: Some third-party applications or services may have limitations or compatibility issues when accessing files stored on a QNAP Turbo Station NAS. It's advisable to check the compatibility of these applications with the NAS device and the operating system or platform you are using.

In summary, while the QNAP Turbo Station TS-2477XU-RP NAS device generally offers broad compatibility, it's important to consider the specific operating system, network protocols, software, and third-party applications you plan to use to ensure smooth and seamless integration.

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

Although the NAS Turbo Station TS-2477XU-RP 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.

Where Are the User’s Files Actually Stored?

The QNAP Turbo Station TS-2477XU-RP network-attached storage keeps QTS (QuTS hero) 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.
