How to recover data from NAS Raidon SafeTANK GR3660-B31A

Raidon SafeTANK GR3660-B31A 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-B31A.

How to recover data from NAS Raidon SafeTANK GR3660-B31A

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 natural disasters such as floods or fires result in data loss for NAS Raidon SafeTANK GR3660-B31A devices?

Yes, natural disasters such as floods or fires can result in data loss for NAS Raidon SafeTANK GR3660-B31A devices. These devices are physical storage systems that can be affected by water damage or heat from fires, leading to potential hardware failure and data loss. It is always recommended to have proper backup and disaster recovery plans in place to mitigate the risk of data loss in such situations.

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

Although NAS SafeTANK GR3660-B31A 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-B31A 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 you explain the storage capacity and expandability options available with the NAS Raidon SafeTANK GR3660-B31A?

    The NAS Raidon SafeTANK GR3660-B31A is a network-attached storage device designed for data storage and sharing in a network environment. It offers various storage capacity and expandability options to meet the needs of different users.

    The SafeTANK GR3660-B31A comes with six drive bays, allowing you to install up to six hard drives or solid-state drives (SSDs) for storage. The storage capacity depends on the size of the drives you install. For example, if you install six 10TB drives, the total storage capacity would be 60TB (terabytes). Similarly, if you install six 2TB drives, the total capacity would be 12TB.

    In terms of expandability, the SafeTANK GR3660-B31A supports RAID configurations. RAID (Redundant Array of Independent Disks) is a technology that combines multiple drives into a single logical unit for enhanced performance, data redundancy, or a combination of both. The device supports RAID levels 0, 1, 5, 6, 10, and JBOD (Just a Bunch of Disks).

    With RAID 0, you can achieve maximum storage capacity and performance by striping data across multiple drives. RAID 1 provides data redundancy by mirroring data on two drives, offering better data protection. RAID 5 and 6 offer a balance between storage capacity, performance, and data redundancy. RAID 10 combines striping and mirroring for both performance and redundancy. JBOD allows you to use each drive independently without any RAID configuration.

    Additionally, the SafeTANK GR3660-B31A supports expansion units, allowing you to connect additional drive bays for increased storage capacity. You can connect up to two expansion units, each providing an additional six drive bays.

    Overall, the NAS Raidon SafeTANK GR3660-B31A provides flexible storage capacity options and expandability through drive bays, RAID configurations, and expansion units, making it suitable for various storage needs and scalability requirements.
