How to recover data from NAS Buffalo TeraStation TS51210RH19212

Buffalo TeraStation TS51210RH19212 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from TeraStation TS51210RH19212.

How to recover data from NAS Buffalo TeraStation TS51210RH19212

Recover data from damaged RAID arrays inaccessible from a computer.

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 a NAS Buffalo TeraStation TS51210RH19212 device's power management settings impact data availability and potential loss?

The power management settings of a NAS Buffalo TeraStation TS51210RH19212 device can impact data availability and potential loss in several ways:

  1. Power Interruptions: If the power management settings are not properly configured, the device may go into sleep mode or shut down during periods of inactivity. This can lead to unexpected power interruptions, causing data loss or corruption.
  2. Data Synchronization: Some power management settings may affect the frequency of data synchronization between the NAS device and connected devices. If the synchronization is infrequent, there is a higher risk of data loss if a failure occurs before the data is synchronized.
  3. RAID Rebuilds: In a RAID configuration, a power outage or improper shutdown can trigger a rebuild process. If the power management settings cause frequent shutdowns or power interruptions, the frequency of RAID rebuilds increases, increasing the risk of data loss during the rebuilding process.
  4. Network Accessibility: Power management settings may affect the NAS device's network accessibility. If the device goes into sleep mode or powers down, it may become temporarily inaccessible from the network, resulting in data unavailability until the device is powered back on.
  5. Backup and Recovery: Power management settings can impact the ability to perform regular backups and recovery operations. If the device is not powered on during scheduled backup times or if it shuts down unexpectedly, backups may not be performed, leaving the data vulnerable to loss.

To mitigate these risks, it is important to configure the power management settings of the NAS device appropriately. This may involve adjusting the sleep mode settings, configuring scheduled power on/off times, ensuring proper UPS (Uninterruptible Power Supply) integration, and regularly monitoring the device's power status to avoid unexpected shutdowns. Additionally, implementing a robust backup strategy and ensuring regular synchronization with connected devices can help minimize the impact of power management settings on data availability and potential loss.

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

Although NAS TeraStation TS51210RH19212 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 TS51210RH19212 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, it is possible to recover data from a NAS Buffalo TeraStation TS51210RH19212 device that has been infected by malware or viruses. However, the process of data recovery will depend on the extent of the infection and the specific type of malware or virus involved.

      Here are some steps you can take to recover data from an infected NAS device:

      1. Disconnect the infected NAS device from the network and isolate it to prevent further spread of the malware or virus.
      2. Assess the extent of the infection by running a thorough antivirus scan on the NAS device. This may help identify and remove any known malware or viruses.
      3. If the antivirus scan is unable to remove the malware or virus, you may need to consult with a professional data recovery service. They have specialized tools and expertise to recover data from infected devices.
      4. In some cases, you may need to perform a factory reset on the NAS device to remove the malware or virus completely. However, this will also erase all data on the device, so it should be used as a last resort.
      5. Once the malware or virus has been removed or isolated, you can attempt to access and recover the data from the NAS device. This can be done by connecting it to a computer or using the NAS management software provided by Buffalo.

      It is important to note that prevention is always better than recovery. Regularly updating the NAS firmware, using strong passwords, and implementing security measures can help prevent malware or virus infections in the first place.
