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.
Can encryption safeguard data stored on NAS Buffalo TeraStation TS5410RN3204 devices?
Yes, encryption can safeguard data stored on NAS Buffalo TeraStation TS5410RN3204 devices. The TeraStation TS5410RN3204 supports various encryption methods, including AES 256-bit encryption for data at rest. This means that the data stored on the device is encrypted and can only be accessed with the correct encryption key. This provides an additional layer of security and protects the data from unauthorized access, even if the device is stolen or compromised.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS TeraStation TS5410RN3204 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.

Step-by-Step Data Recovery with Hetman RAID Recovery
This program restores data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS5410RN3204. 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 TS5410RN3204 has 4 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- RAID 6;
- 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:
-
Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
-
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
-
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.
-
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 TS5410RN3204 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.

In most cases, data recovery from a NAS Buffalo TeraStation TS5410RN3204 device can still be performed even if there are issues with the motherboard or system board. However, it would depend on the specific nature of the issues and the extent of the damage.
If the motherboard or system board is completely non-functional, it may be necessary to replace it with a working one before attempting data recovery. This can be done by contacting Buffalo support or a professional data recovery service.
If the motherboard or system board is partially functional or has minor issues, it may still be possible to access the data by connecting the hard drives to another compatible system or by using specialized data recovery tools.
It is important to note that attempting data recovery on your own, especially if you are not experienced in handling hardware components, can be risky and may lead to further damage or data loss. It is recommended to seek professional assistance in such cases to ensure the best chance of successful data recovery.
