How to recover data from Digiever MN-2136 Pro+ 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 Digiever MN-2136 Pro+

Digiever MN-2136 Pro+ NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from MN-2136 Pro+.

How to recover data from NAS Digiever MN-2136 Pro+

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 Digiever 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 shutdown or unclean system reboots lead to data loss on NAS Digiever MN-2136 Pro+ devices?

Improper shutdown or unclean system reboots can potentially lead to data loss on any device, including NAS Digiever MN-2136 Pro+ devices. When a system is not shut down properly, there is a risk of data corruption or incomplete write operations, which can result in the loss of data or damage to the file system.

To minimize the chances of data loss, it is important to always follow the proper shutdown procedures recommended by the manufacturer. This typically involves using the appropriate shutdown command or interface to safely power off the device.

Additionally, it is advisable to regularly backup your data to an external storage device or a cloud-based backup service. This way, even if data loss occurs due to an improper shutdown, you can restore your important files from the backup.

It is always recommended to consult the user manual or contact the manufacturer's support for specific instructions on proper shutdown and reboot procedures for your Digiever MN-2136 Pro+ NAS device.

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

Although NAS MN-2136 Pro+ 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.

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 Digiever MN-2136 Pro+ 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 the NAS Digiever MN-2136 Pro+ handle high traffic and intensive website operations, such as e-commerce transactions or media streaming? What are its performance limitations in such scenarios?

    The Digiever MN-2136 Pro+ is a network attached storage (NAS) device primarily designed for video surveillance applications. While it can handle moderate website operations, it may have limitations when it comes to high traffic and intensive website operations like e-commerce transactions or media streaming.

    The performance limitations of the MN-2136 Pro+ in such scenarios are primarily due to its hardware specifications. It is equipped with an Intel Atom processor, which may not provide sufficient processing power for handling heavy website traffic or media streaming demands. Additionally, the device may have limited RAM and storage capacity, which can further impact its performance in high-demand scenarios.

    For e-commerce transactions, the MN-2136 Pro+ may not be able to handle a large number of concurrent users or process transactions quickly enough to ensure a smooth user experience. Similarly, for media streaming, the device may struggle to deliver high-quality and uninterrupted streaming due to its hardware limitations.

    If you require a NAS device specifically for high traffic and intensive website operations, it is recommended to consider more powerful options with higher-end processors, larger RAM capacity, and scalable storage solutions.
