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 Buffalo 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.

How can the use of specific file-sharing protocols impact data loss risks on NAS Buffalo TeraStation TS3410RN0802 devices?

The use of specific file-sharing protocols can impact data loss risks on NAS Buffalo TeraStation TS3410RN0802 devices in several ways:

1. Access Control: Different file-sharing protocols have varying levels of access control mechanisms. Some protocols, like FTP, may provide less granular control over user permissions, increasing the risk of unauthorized access and potential data loss. It is important to choose a protocol that offers robust access control features to minimize the risk of data loss.
2. Encryption: File-sharing protocols differ in their support for encryption. Protocols like FTP may transmit data in plain text, making it vulnerable to interception and unauthorized access. Using protocols such as SFTP (SSH File Transfer Protocol) or HTTPS (HTTP Secure) can help mitigate the risk of data loss by encrypting data during transmission.
3. Data Integrity: Certain file-sharing protocols may not provide mechanisms for ensuring data integrity during transmission. Without proper integrity checks, data corruption or loss may go undetected, leading to potential data loss. Choosing protocols that support integrity checks, such as checksums or hashing, can help identify and mitigate data loss risks.
4. Network Vulnerabilities: Some file-sharing protocols may be more susceptible to network vulnerabilities, such as man-in-the-middle attacks or packet sniffing. These vulnerabilities can expose data to unauthorized access and increase the risk of data loss. Selecting protocols that have built-in security features, such as secure authentication and encryption, can help mitigate these risks.
5. Compatibility and Interoperability: The choice of file-sharing protocol can impact compatibility and interoperability with different operating systems and devices. Incompatibilities may lead to data loss if files become corrupted or inaccessible during transfer or sharing. It is essential to ensure that the chosen protocol is supported by all relevant devices and operating systems to minimize the risk of data loss.

To reduce data loss risks on NAS Buffalo TeraStation TS3410RN0802 devices, it is advisable to choose file-sharing protocols that offer robust access control, encryption, data integrity checks, network security features, and compatibility with the intended environment. Additionally, implementing regular backups and following best practices for data management can further enhance data loss prevention on these devices.

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

Although the NAS TeraStation TS3410RN0802 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 Buffalo TeraStation TS3410RN0802. 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 Buffalo

TeraStation TS3410RN0802 has 2 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• JBOD;

NAS supports:

• exFAT, VFAT, FAT 12 / 16 / 32;
• NTFS / ReFS;
• APFS / HFS+;
• Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
• VMFS / HikvisionFS;

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 Buffalo TeraStation TS3410RN0802 network-attached storage keeps OS Linux 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.
