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 known limitations or performance bottlenecks that can increase data loss risks for NAS QNAP Turbo Station TS-131 / TS-131K / TS-131P devices?

There are several known limitations and performance bottlenecks that can increase data loss risks for NAS QNAP Turbo Station TS-131 / TS-131K / TS-131P devices. Some of these include:

1. Limited hardware resources: These devices have limited processing power, memory, and storage capacity. This can lead to performance issues and potentially increase the risk of data loss if the device becomes overwhelmed or fails.
2. Single disk configuration: The TS-131 series devices typically come with a single hard drive bay, which means they do not support RAID configurations for data redundancy. If the single disk fails, there is a higher risk of data loss.
3. Lack of backup options: These devices may not have built-in backup features or support for external backup options. This can make it difficult to create reliable backups of your data, increasing the risk of permanent data loss in case of hardware failure or other issues.
4. Limited scalability: The TS-131 series devices have a limited number of drive bays, which can limit the overall storage capacity and scalability. If you need to expand your storage in the future, you may need to consider upgrading to a different NAS model.
5. Network limitations: The performance of these devices can be affected by network limitations, such as bandwidth constraints or network congestion. This can impact data transfer speeds and potentially increase the risk of data loss if the network is not reliable.

To mitigate these risks, it is recommended to implement a backup strategy, regularly monitor the health of the device and hard drive, and consider upgrading to a higher-end NAS model with better hardware resources and support for RAID configurations.

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

Although the NAS Turbo Station TS-131 / TS-131K / TS-131P 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.

   How to Order Remote Data Recovery

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with QNAP Turbo Station TS-131 / TS-131K / TS-131P. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

How to recover data from a QNAP

Turbo Station TS-131 / TS-131K / TS-131P has 1 HDD slots, and it supports the following array types:

• Q-RAID 1;

NAS supports:

• EXT4;
• EXT3;
• FAT32 (External Disk Only);
• NTFS (External Disk Only);
• HFS+ (External Disk Read Only);

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

• Overwriting during the recovery process;
• Additional data loss caused by bad sectors;
• User errors.

To create a disk image, follow these steps:

1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

   

4. Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

   

Where Are the User’s Files Actually Stored?

The QNAP Turbo Station TS-131 / TS-131K / TS-131P network-attached storage keeps QTS 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.
