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 data be recovered from a NAS Buffalo TeraStation TS-RI1.0TGL/R5 device after a malfunction or data loss event?

If you are facing a data loss event or malfunction with your NAS Buffalo TeraStation TS-RI1.0TGL/R5 device, you can try the following steps to recover your data:

  1. Check the hardware: Ensure that all cables, power supply, and connections are secure and functioning properly. Sometimes, a loose connection or power issue can cause data loss or malfunction.
  2. Restart the device: Power off the TeraStation, unplug it from the power source, wait for a few minutes, and then plug it back in. Power it on and see if it resolves the issue. Sometimes, a simple restart can fix minor glitches.
  3. Use the Buffalo NAS Navigator software: Install and run the Buffalo NAS Navigator software on your computer. It should detect the TeraStation on your network. If it does, try accessing the device through the software and see if you can retrieve your data.
  4. Access the TeraStation through web interface: Open a web browser and enter the IP address of the TeraStation in the address bar. If you can access the web interface, navigate to the settings and check if there are any error messages or alerts. You might be able to troubleshoot and recover your data from there.
  5. Contact Buffalo support: If the above steps do not work, it is recommended to contact Buffalo's customer support. They can provide you with specific guidance and assistance based on your situation. They might suggest advanced recovery methods or refer you to a professional data recovery service.
  6. Professional data recovery service: If all else fails, and your data is critical, you can consider contacting a professional data recovery service. These services specialize in recovering data from malfunctioning or damaged storage devices. However, keep in mind that professional data recovery can be expensive and there is no guarantee of success.

Remember, it is always recommended to have regular backups of your important data to avoid such data loss situations.

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

Although the NAS TeraStation TS-RI1.0TGL/R5 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 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-RI1.0TGL/R5 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.

      Yes, there are specific precautions that need to be taken while attempting data recovery from a NAS Buffalo TeraStation TS-RI1.0TGL/R5 device. Here are some important points to consider:

      1. Avoid further data writes: Do not write any new data to the NAS device as it may overwrite the existing data, making recovery difficult or impossible.
      2. Disconnect the NAS from the network: Disconnect the NAS device from the network to prevent any automatic synchronization or updates that may occur, potentially causing data loss.
      3. Power off the NAS: Turn off the NAS device properly to prevent any further damage or data corruption. Avoid abrupt power cuts or unplugging.
      4. Avoid DIY attempts: It is recommended to not attempt data recovery on your own unless you have sufficient knowledge and experience. Mishandling the device or improper recovery methods can lead to permanent data loss.
      5. Consult a professional data recovery service: Contact a professional data recovery service that specializes in NAS recovery. They have the expertise, tools, and cleanroom facilities to safely recover data from the NAS device.
      6. Provide necessary information: When contacting a data recovery service, provide them with all the relevant information about the NAS device, such as the model number, RAID configuration, any error messages, and the circumstances of the data loss.
      7. Do not replace drives: If a drive failure is suspected, do not attempt to replace the drives yourself. Replacing drives without proper understanding of the RAID configuration can result in further data loss. Leave it to the professionals.

      Remember, data recovery from a NAS device can be complex and delicate. It is advisable to seek professional help to maximize the chances of successful recovery without causing any further damage.
