Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like Buffalo also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

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 take hard disks out of the NAS and connect them to a PC?

Although NAS TeraStation TS-RI1.0TGL/R5 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files 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.
