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.

What is a NAS Buffalo TeraStation WS-WV4.0TL/R1 (Network Attached Storage) device?

The NAS Buffalo TeraStation WS-WV4.0TL/R1 is a Network Attached Storage device manufactured by Buffalo Technology.

NAS devices are storage systems that are connected to a network and provide centralized data storage and file sharing capabilities to multiple users and devices on the network. They are often used in homes and small businesses to store and backup files, media, and other data.

The Buffalo TeraStation WS-WV4.0TL/R1 is a specific model of NAS device offered by Buffalo Technology. It has a storage capacity of 4 terabytes (TB) and is designed for use in small office or home office (SOHO) environments. It supports RAID configurations for data redundancy and protection, and it can be accessed and managed remotely over the internet. The device also provides features like automatic backups, cloud integration, and support for various file sharing protocols.

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

Although the NAS TeraStation WS-WV4.0TL/R1 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.

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 WS-WV4.0TL/R1 network-attached storage keeps Windows Storage Server 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.

  Yes, data recovery from a NAS Buffalo TeraStation device can still be possible even if the device is experiencing intermittent connectivity issues. However, the success of the data recovery process depends on the specific nature of the connectivity issues and the extent of the damage to the device.
  If the intermittent connectivity issues are related to network connectivity or firmware/software problems, it may be possible to resolve them and access the data on the device. In such cases, troubleshooting steps like checking network settings, updating firmware, or trying different network cables/ports can help restore connectivity.
  However, if the connectivity issues are due to hardware failure or physical damage to the device, the data recovery process becomes more challenging. In such cases, it is recommended to contact a professional data recovery service provider who specializes in NAS devices. They have specialized tools and expertise to recover data from damaged NAS devices.
  It's important to note that attempting DIY data recovery methods without proper knowledge and tools can further damage the device and make data recovery more difficult or even impossible.
