How to recover data from NAS Uniview VS-R5320-B2X

Uniview VS-R5320-B2X 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-R5320-B2X.

How to recover data from NAS Uniview VS-R5320-B2X

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.

What are the risks of data loss due to firmware or software malfunctions in NAS Uniview VS-R5320-B2X devices?

The risks of data loss due to firmware or software malfunctions in NAS Uniview VS-R5320-B2X devices can include:

  1. Corruption of data: Firmware or software malfunctions can lead to data corruption, rendering the stored data unreadable or unusable.
  2. Inaccessibility of data: If the firmware or software malfunctions, it may result in the NAS device becoming unresponsive or inaccessible, making it difficult or impossible to retrieve the stored data.
  3. Loss of data integrity: Malfunctions can cause data integrity issues, where the data becomes inconsistent or incomplete, leading to potential loss or inaccuracies in the stored information.
  4. System instability: Firmware or software malfunctions can cause the NAS device to become unstable, resulting in frequent crashes or system failures. This instability can increase the risk of data loss.
  5. Data deletion: In some cases, firmware or software malfunctions can lead to unintentional deletion of data, either through system errors or bugs. This could result in permanent loss of critical information.
  6. Limited recovery options: If data loss occurs due to firmware or software malfunctions, the recovery options may be limited or costly. Depending on the severity of the issue, it may require professional assistance or specialized tools to recover the lost data.

To mitigate these risks, it is essential to regularly backup data stored on the NAS device, ensure the firmware and software are up to date, and implement appropriate security measures such as strong passwords and access controls.

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