How to recover data from Raidon SafeTANK GR3660-B31 NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Raidon SafeTANK GR3660-B31

Raidon SafeTANK GR3660-B31 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from SafeTANK GR3660-B31.

How to recover data from NAS Raidon SafeTANK GR3660-B31

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 Raidon also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

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

Although NAS SafeTANK GR3660-B31 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 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.
