How to recover data from Uniview VX1836-NAS 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 Uniview VX1836-NAS

Uniview VX1836-NAS NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VX1836-NAS.

How to recover data from NAS Uniview VX1836-NAS

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 Uniview 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 encryption safeguard data stored on NAS Uniview VX1836-NAS devices?

Yes, encryption can safeguard data stored on NAS (Network Attached Storage) devices such as Uniview VX1836-NAS. NAS devices typically have built-in encryption features that allow users to encrypt their data at rest, ensuring that it remains secure even if the device is stolen or compromised.

There are two common types of encryption used in NAS devices:

  1. Full Disk Encryption (FDE): This type of encryption encrypts the entire hard drive or storage volume, making it inaccessible without the decryption key. FDE protects data at rest, ensuring that even if the physical drive is removed from the NAS device, the data remains encrypted and unreadable.
  2. Folder-Level Encryption: Some NAS devices offer folder-level encryption, where specific folders or files are encrypted individually. This allows users to selectively encrypt sensitive data while leaving other data unencrypted. Folder-level encryption is useful when you want to protect specific files or folders within the NAS.

It is important to note that encryption alone is not sufficient to secure data on a NAS device. It should be used in combination with other security measures such as strong access controls, authentication mechanisms, regular software updates, and secure network configurations to ensure comprehensive data protection.

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

Although NAS VX1836-NAS 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.

VX1836-NAS has 36 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • RAID 50;
  • RAID 60;
  • JBOD;

NAS supports:

  • 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 Uniview VX1836-NAS 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.
