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.

Can power outages or surges affect data stored in NAS Buffalo TeraStation TS5810DN1604 devices?

Yes, power outages or surges can potentially affect data stored in NAS Buffalo TeraStation TS5810DN1604 devices. Power outages can lead to sudden shutdowns of the device, which can cause data corruption or loss if the device is not properly shut down. Power surges, on the other hand, can introduce excessive voltage or current that may damage the internal components of the device, potentially leading to data loss or hardware failure.

To protect against these risks, it is recommended to use uninterruptible power supply (UPS) devices to provide backup power during outages and to install surge protectors to safeguard against power surges. Additionally, regularly backing up data to external storage or cloud services is advisable to ensure data redundancy and minimize the impact of any potential data loss.

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

Although the NAS TeraStation TS5810DN1604 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 TS5810DN1604 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.

      Recovering data from a NAS device that has been affected by a ransomware attack can be challenging but not impossible. Here are some steps you can take:

      1. Isolate the affected device: Disconnect the NAS device from the network immediately to prevent further spread of the ransomware.
      2. Report the incident: Contact law enforcement and report the ransomware attack. They may provide guidance and investigate the incident.
      3. Assess the damage: Determine the extent of the ransomware attack and identify which files have been encrypted. This will help you understand the scope of the recovery process.
      4. Remove the ransomware: Consult with cybersecurity professionals to ensure the complete removal of the ransomware from the NAS device. They may provide specific instructions or tools to assist in this process.
      5. Restore from backups: If you have regular backups of your data, you can restore the unaffected data from those backups. Ensure that the backups were created before the ransomware attack occurred to prevent reinfection.
      6. Seek professional help: If you don't have backups or are unable to recover the data yourself, consult with a professional data recovery service. They may have specialized tools and techniques to recover data from compromised devices.

      Remember, prevention is key to avoiding ransomware attacks. Regularly update your NAS device's firmware, maintain strong security practices, and educate users about the risks of phishing and suspicious downloads to minimize the chances of future attacks.
