Promise Vess 1720i NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from Vess 1720i.

How to recover data from NAS Promise Vess 1720i

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 Promise also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can file system corruption impact data integrity on NAS Promise Vess 1720i devices?

File system corruption can have a significant impact on data integrity on NAS Promise Vess 1720i devices. Here are some ways it can affect data integrity:

  1. Data Loss: File system corruption can lead to the loss of data stored on the NAS device. Corruption can cause files and directories to become inaccessible or completely disappear from the file system.
  2. Data Inconsistency: Corruption can result in data inconsistencies where the information stored in files becomes incorrect or incomplete. This can lead to data errors and make the data unreliable or unusable.
  3. Data Modification: Corruption can modify the content of files, causing data to become corrupted or altered. This can result in data integrity issues, especially if critical system files or important user data are affected.
  4. System Instability: File system corruption can make the NAS device unstable and cause it to crash or become unresponsive. This can disrupt ongoing operations and potentially lead to data corruption or loss.
  5. Difficulty in Recovery: Recovering data from a corrupted file system can be challenging and may require specialized tools or professional assistance. In some cases, data recovery may not be possible, leading to permanent data loss.

To mitigate the impact of file system corruption on data integrity, it is important to regularly backup data stored on the NAS device. Additionally, performing regular file system checks and maintenance can help identify and fix any corruption issues before they cause significant data loss or integrity problems.

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

Although NAS Vess 1720i 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.

Questions and answers

  • What is DLNA and how does it work in the context of media streaming and sharing?

    DLNA stands for Digital Living Network Alliance. It is a set of guidelines and standards that enable devices to share and stream media content over a home network. DLNA allows different devices, such as smartphones, tablets, computers, smart TVs, and gaming consoles, to communicate and share media files seamlessly.

    DLNA works by establishing a network connection between compatible devices. The devices must be connected to the same local network, such as a Wi-Fi network or Ethernet, for DLNA to function. Once connected, DLNA enables devices to discover and communicate with each other.

    To share media content, a DLNA-enabled device acts as a server, making its media files available to other devices on the network. This server device indexes and organizes the media files, allowing other devices to access and stream them. The media files can include photos, videos, music, and even recorded television shows.

    DLNA also defines different roles for devices in the network. For example, a device can act as a Digital Media Server (DMS) to share media files, a Digital Media Player (DMP) to access and play media files, or a Digital Media Controller (DMC) to control the playback of media files on another device.

    When a DLNA-compatible device wants to access media files from a server device, it sends a request to the server. The server then responds by providing a list of available media files. The requesting device can then choose a file to stream or play, and the server device streams the content over the network to the requesting device.

    DLNA supports various media formats and codecs, allowing for compatibility across different devices. It simplifies the process of sharing and streaming media content within a home network, enabling users to access their media files from different devices without the need for complex configurations or additional software.
