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 Drive Station HD-W1.0TIU2/R1 (Network Attached Storage) device?

The NAS Buffalo DriveStation HD-W1.0TIU2/R1 is a Network Attached Storage (NAS) device manufactured by Buffalo Technology.

NAS devices are essentially storage devices that are connected to a network, allowing multiple users to access and share files over the network. They are commonly used in homes and small businesses to centralize and backup data, and provide a convenient way to access files from multiple devices.

The Buffalo DriveStation HD-W1.0TIU2/R1 is a specific model of NAS device offered by Buffalo Technology. The "HD" in the name refers to the device's capacity for storing large amounts of data, and the "W1.0TIU2/R1" indicates the specific model number. This particular model offers a 1.0TB (terabyte) storage capacity.

Overall, the Buffalo DriveStation HD-W1.0TIU2/R1 is designed to provide reliable and easily accessible network storage for personal or small business use.

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

Although the NAS Drive Station HD-W1.0TIU2/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:

  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.

Where Are the User’s Files Actually Stored?

The Buffalo Drive Station HD-W1.0TIU2/R1 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.

      Recovering data from a NAS Buffalo Drive Station HD-W1.0TIU2/R1 device that has been affected by a natural disaster such as flooding or earthquake can be challenging. The chances of successful data recovery depend on the extent of damage caused to the device.

      If the device has been completely submerged in water or severely damaged, the chances of recovering data may be slim. In such cases, it is recommended to seek professional data recovery services who specialize in dealing with damaged storage devices.

      However, if the device has not suffered extensive damage and is still functional, there might be a possibility of recovering data. In such cases, it is crucial to disconnect the device from power and avoid further damage. It is recommended to consult with a professional data recovery service as they have the expertise and specialized tools to handle such situations.

      Remember, data recovery from a device affected by a natural disaster is not guaranteed, and the success of recovery depends on various factors including the extent of damage and the condition of the device.
