Buffalo TeraStation TS51210RH12012 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 TS51210RH12012.

How to recover data from NAS Buffalo TeraStation TS51210RH12012

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.

Are there any specific system logs or event notifications to monitor for early detection of data loss on NAS Buffalo TeraStation TS51210RH12012 devices?

Yes, there are specific system logs and event notifications that can be monitored for early detection of data loss on NAS Buffalo TeraStation TS51210RH12012 devices. Some important logs and notifications to monitor include:

  1. System Logs: The system logs on the TeraStation device can provide valuable information about any errors or issues that may be occurring. These logs can be accessed through the device's web interface or via SSH. Look for any error messages related to disk failures, file system corruption, or other issues that may lead to data loss.
  2. SMART Monitoring: TeraStation devices support SMART (Self-Monitoring, Analysis, and Reporting Technology) monitoring for hard drives. SMART data provides information about the health and status of the drives, including any potential failures or errors. Monitoring SMART attributes can help detect early signs of drive failure, allowing you to take preventive action before data loss occurs.
  3. Email Notifications: TeraStation devices can be configured to send email notifications for various events, including disk errors, RAID failures, and system warnings. Ensure that email notifications are properly set up and regularly check the inbox for any alerts related to potential data loss.
  4. RAID Status Monitoring: TeraStation devices typically use RAID (Redundant Array of Independent Disks) configurations for data redundancy and protection. Monitor the RAID status regularly to ensure that all drives are functioning correctly and that the array is in a healthy state. Any degradation or failure in the RAID array can lead to data loss.
  5. File System Check Results: The TeraStation device periodically performs file system checks to detect and repair any inconsistencies or errors. Monitor the results of these checks to identify any file system issues that may indicate potential data loss or corruption.

It is important to regularly review and monitor these logs and notifications to detect any early signs of data loss and take appropriate action to prevent further damage or loss of data.

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

Although NAS TeraStation TS51210RH12012 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS51210RH12012. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a Buffalo

TeraStation TS51210RH12012 has 12 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • RAID 50;
  • RAID 60;
  • JBOD;

NAS supports:

  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

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 TS51210RH12012 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.

    Can data recovery from a NAS Buffalo TeraStation TS51210RH12012 device be done if the device is showing signs of network congestion or bandwidth issues?
    • Hetman Software
      Hetman Software 2.09.2023 12:00 #

      Yes, data recovery from a NAS Buffalo TeraStation TS51210RH12012 device can still be possible even if the device is experiencing network congestion or bandwidth issues. In such cases, it may be challenging to access the data directly from the device due to the slow or unstable network connection.

      However, there are alternative methods to recover the data:

      1. Direct Connection: If possible, connect the NAS device directly to a computer using an Ethernet cable. This bypasses the network congestion and allows for direct access to the data.
      2. Remove Hard Drives: If the NAS device supports hot-swappable drives, you can remove the hard drives from the device and connect them to a computer using a SATA-to-USB adapter or an external hard drive enclosure. This allows you to access the data without relying on the NAS device's network connection.
      3. Professional Data Recovery: If the above methods are not feasible or if the data is critically important, you can seek professional data recovery services. Data recovery experts have specialized tools and techniques to recover data from NAS devices, even in challenging situations. They can often recover data directly from the hard drives, bypassing any network-related issues.

      It's important to note that attempting any data recovery process carries some risk, and it's recommended to consult with a professional if you are unsure or if the data is highly valuable.
