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 Raidon 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 Raidon SafeTANK GR3660-B31 devices?

Yes, power outages or surges can potentially affect the data stored in NAS Raidon SafeTANK GR3660-B31 devices. NAS devices typically have built-in mechanisms to protect against power fluctuations, such as surge protectors and uninterruptible power supplies (UPS). However, if the power outage or surge is severe enough, it can still cause damage to the NAS device or corrupt the data stored on it.

To mitigate the risk of data loss or corruption, it is recommended to use a UPS to provide backup power to the NAS device during power outages. Additionally, regularly backing up the data stored on the NAS to an external storage device or cloud storage can help safeguard against potential data loss.

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

Although the NAS SafeTANK GR3660-B31 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 Raidon SafeTANK GR3660-B31 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.

    Is it possible to recover data from a NAS Raidon SafeTANK GR3660-B31 device that has undergone a factory reset or system restore?
    • Hetman Software
      Hetman Software 5.09.2023 00:59 #

      Recovering data from a NAS device that has undergone a factory reset or system restore can be challenging, but it is not impossible. Here are a few factors to consider:

      1. Factory Reset: A factory reset usually erases all data and settings on the NAS device, including user data and configurations. This makes data recovery more difficult as the original data may have been overwritten.
      2. RAID Configuration: The RAID configuration used in the NAS device can impact data recovery. If the NAS is configured with RAID 0 (striping), data recovery becomes more complex as it spreads the data across multiple drives without redundancy. However, if the NAS is configured with RAID 1, 5, 6, or 10 (mirroring or parity), there may be a higher chance of recovering data as these configurations provide redundancy.
      3. Data Recovery Services: If you are unable to recover the data yourself, you can seek professional data recovery services. These services specialize in recovering data from various storage devices, including NAS devices. They have specialized tools and techniques to recover data even from challenging scenarios.

      It is important to note that data recovery success depends on various factors, including the extent of data overwriting, the RAID configuration, and the expertise of the data recovery service. It is recommended to consult with a professional data recovery service to assess the feasibility of data recovery from your specific NAS device.
