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

Although the NAS TeraStation TS51210RH19212 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 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.
