How to recover data from Instek NR3800-2U 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 Instek NR3800-2U

Instek NR3800-2U NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from NR3800-2U.

How to recover data from NAS Instek NR3800-2U

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 Instek 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 virtualization technologies impact data loss risks in NAS Instek NR3800-2U devices?

Yes, virtualization technologies can impact data loss risks in NAS Instek NR3800-2U devices.

Virtualization allows for the creation of virtual machines (VMs) that can run multiple operating systems and applications on a single physical server. By using virtualization, you can isolate different applications and workloads, reducing the risk of data loss caused by software conflicts or crashes.

Additionally, virtualization technologies offer features such as snapshots and backups that can help protect against data loss. Snapshots allow you to capture the state of a VM at a specific point in time, so if data is accidentally deleted or corrupted, you can revert to a previous snapshot to restore the data. Backups can also be performed on VMs, ensuring that data is regularly copied and stored in a separate location for disaster recovery purposes.

By leveraging virtualization technologies, you can enhance the reliability and availability of data stored in NAS Instek NR3800-2U devices, reducing the risk of data loss.

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

Although NAS NR3800-2U 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 Instek NR3800-2U. 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.

  • 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 Instek NR3800-2U 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 Instek NR3800-2U device be done if the disks have been reformatted?
    • Hetman Software
      Hetman Software 8.09.2023 22:59 #

      If the disks of a NAS Instek NR3800-2U device have been reformatted, data recovery may still be possible, but it depends on the extent of the reformatting and the actions taken afterward. Here are a few factors to consider:

      1. Type of reformatting: If the disks were quick-formatted or the file system was simply overwritten with a new one, there is a higher chance of recovering data using specialized recovery software. However, if the disks were fully formatted or overwritten with new data, the chances of recovery decrease significantly.
      2. Time elapsed after reformatting: The longer the time between the reformatting and the data recovery attempt, the lower the chances of successful recovery. This is because the more the disks are used after reformatting, the higher the probability that the original data has been overwritten.
      3. Data recovery tools and expertise: Professional data recovery services or specialized software can greatly increase the chances of recovering data from reformatted disks. These tools can scan the disks for remnants of the original data and attempt to reconstruct it.

      It is important to note that data recovery is not always guaranteed, especially if the disks have been extensively overwritten or damaged. Therefore, it is recommended to consult with a professional data recovery service or expert who can assess the specific situation and provide appropriate guidance.
