How to recover data from Uniview VS-R5328S-C2X@AI 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 VS-R5328S-C2X@AI

Uniview VS-R5328S-C2X@AI NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VS-R5328S-C2X@AI.

How to recover data from NAS Uniview VS-R5328S-C2X@AI

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 improper network configuration or firewall settings result in data loss on NAS Uniview VS-R5328S-C2X@AI devices?

Improper network configuration or firewall settings can potentially result in data loss on NAS (Network Attached Storage) devices, including the Uniview VS-R5328S-C2X@AI. Here are a few scenarios where data loss may occur:

  1. Inadequate backup: If the NAS is not properly backed up, any network configuration or firewall misconfiguration that leads to data corruption or deletion may result in permanent data loss.
  2. Inaccessible NAS: Incorrect firewall settings or network configuration can make the NAS inaccessible from the network, preventing users from accessing or retrieving data stored on it.
  3. Data corruption during transmission: Firewall settings that block certain network ports or protocols may interfere with the transmission of data to and from the NAS. This can cause data corruption, leading to potential loss of data integrity.
  4. Unauthorized access: Improper network configuration or firewall settings can leave the NAS vulnerable to unauthorized access. In such cases, malicious actors may gain unauthorized access to the NAS and delete or modify data, resulting in data loss.

To mitigate the risk of data loss, it is important to ensure proper network configuration and firewall settings for NAS devices. This includes configuring appropriate firewall rules, opening required network ports, enabling secure remote access protocols (such as SSH or VPN), and regularly backing up the data stored on the NAS to an off-site location or another storage device.

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

Although NAS VS-R5328S-C2X@AI 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 Uniview VS-R5328S-C2X@AI. 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.

  • 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 VS-R5328S-C2X@AI 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.

      Recovering data from a NAS (Network Attached Storage) device that has undergone a system restore or factory reset can be challenging. When a system restore or factory reset is performed, it typically erases all data and settings on the device, including user files and configurations.

      However, there might still be some possibilities to recover the data depending on the specific circumstances:

      1. Data recovery software: You can try using specialized data recovery software that is designed to recover lost or deleted files from storage devices. These tools can sometimes retrieve data even after a system restore or factory reset. However, success rates may vary, and it's important to act quickly to minimize data overwriting.
      2. Professional data recovery services: If the data is critical and cannot be recovered using software solutions, you can contact professional data recovery services. These experts have specialized tools and techniques to recover data from various storage devices, including NAS devices. They may be able to recover the data even after a system restore or factory reset.

      It's important to note that the success of data recovery depends on various factors, including the extent of the reset, the time that has passed since the reset, and the actions taken after the reset. It's recommended to consult with a professional data recovery service for the best chance of recovering your data.
