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 hardware upgrades or modifications lead to data loss if not properly executed on NAS Buffalo TeraStation TS-8VH8.0TL/R6 devices?

Yes, hardware upgrades or modifications on NAS Buffalo TeraStation TS-8VH8.0TL/R6 devices can potentially lead to data loss if not properly executed. Any time you modify or upgrade hardware components, there is a risk of damaging or corrupting the data stored on the device. This can happen due to various reasons such as improper installation, compatibility issues, or power failures during the process.

To minimize the risk of data loss during hardware upgrades or modifications, it is important to follow the manufacturer's instructions and guidelines carefully. It is also recommended to backup all important data before making any changes to the hardware. Additionally, ensuring that the device is powered off and disconnected from the power source before performing any hardware modifications can help prevent accidental data loss.

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

Although the NAS TeraStation TS-8VH8.0TL/R6 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.

Step-by-Step Data Recovery with Hetman RAID Recovery

Hetman Raid Recovery

This program restores data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS-8VH8.0TL/R6. 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 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.

Where Are the User’s Files Actually Stored?

The Buffalo TeraStation TS-8VH8.0TL/R6 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.

    Can data recovery from a NAS Buffalo TeraStation TS-8VH8.0TL/R6 device be performed if there are issues with the network router or switch?

      Yes, data recovery from a Buffalo TeraStation TS-8VH8.0TL/R6 device can still be performed even if there are issues with the network router or switch. The NAS device itself stores the data on its internal hard drives, so as long as the drives are functional, the data can be recovered.

      To perform the data recovery, you may need to directly connect the NAS device to a computer using an Ethernet cable or remove the hard drives from the NAS and connect them to a computer using a SATA to USB adapter or docking station. This will bypass the network router or switch and allow you to access the data on the drives.
