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 that can result in data loss for NAS QNAP Turbo Station TS-h2477XU-RP devices?

There can be several compatibility issues that may result in data loss for NAS QNAP Turbo Station TS-h2477XU-RP devices. Some of the common issues include:

Incompatible hard drives: Using incompatible hard drives can lead to data loss. It is important to ensure that the hard drives you use are compatible with the QNAP Turbo Station model. QNAP provides a compatibility list on their website for reference.
Firmware and software compatibility: Incompatibility between the firmware version of the QNAP Turbo Station and the software installed on client devices can cause data loss. It is recommended to keep both the firmware and software up to date to avoid any compatibility issues.
Network and connectivity issues: Unstable network connections, network configuration conflicts, or incompatible network equipment can disrupt data transfer and potentially lead to data loss. It is essential to have a stable and compatible network setup.
Power supply issues: Inadequate power supply or power fluctuations can result in data loss. It is crucial to ensure that the QNAP Turbo Station is connected to a reliable power source and protected against power surges.
Hardware failures: Any hardware failure in the QNAP Turbo Station, such as disk controller failure or motherboard failure, can potentially lead to data loss. Regular backups and proper hardware maintenance can help mitigate the risk of data loss in such cases.

To minimize the chances of data loss, it is advisable to follow QNAP's guidelines, keep the firmware and software updated, use compatible hardware, maintain a stable network environment, and regularly backup your data.

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

Although the NAS Turbo Station TS-h2477XU-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:

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.
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.
Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.
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-h2477XU-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.

How does data recovery from NAS QNAP Turbo Station TS-h2477XU-RP differ from other storage devices?

Reply
- Hetman Software 19.09.2023 05:59 #
  Data recovery from a NAS QNAP Turbo Station TS-h2477XU-RP differs from other storage devices in a few key ways:
  RAID Configuration: The QNAP Turbo Station TS-h2477XU-RP typically uses a RAID (Redundant Array of Independent Disks) configuration to distribute data across multiple hard drives for increased performance and fault tolerance. This means that data recovery involves understanding and reconstructing the RAID configuration to recover the data.
  Network Connectivity: Unlike traditional storage devices like internal hard drives or external hard drives, a NAS is connected to a network and accessible by multiple users simultaneously. This network connectivity introduces additional complexities during data recovery, as the NAS might have been accessed by multiple users or applications, potentially causing data corruption or overwriting.
  Operating System and File System: NAS devices often run their own operating system and file system, which can be different from those found in traditional storage devices. QNAP Turbo Station TS-h2477XU-RP, for example, runs the QTS operating system and typically uses the ext4 file system. Data recovery specialists need to have knowledge and expertise in these specific systems to successfully recover data.
  Hardware and Software Integration: NAS devices like QNAP Turbo Station TS-h2477XU-RP have specialized hardware components and software features that are designed for network storage functionality. This integration of hardware and software can add complexity to the data recovery process, requiring specialized tools and techniques to recover the data.
  Overall, data recovery from a NAS QNAP Turbo Station TS-h2477XU-RP requires a deep understanding of RAID configurations, network connectivity, specialized operating systems, and file systems specific to NAS devices. It is recommended to consult professional data recovery services with expertise in NAS recovery to ensure a higher chance of successful data retrieval.
