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 Infortrend EonStor GS 2016

Infortrend EonStor GS 2016 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from EonStor GS 2016.

How to recover data from NAS Infortrend EonStor GS 2016

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 Infortrend 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 network issues impact the data stored on NAS Infortrend EonStor GS 2016 devices?

Network issues can have several impacts on the data stored on NAS Infortrend EonStor GS 2016 devices:

  1. Data corruption: Network issues such as packet loss, latency, or network congestion can lead to data corruption. If packets are dropped or delayed during transmission, it can result in incomplete or incorrect data being stored on the NAS device.
  2. Data loss: Network issues can cause interruptions in data transfers between the NAS device and connected clients. If the connection is lost during a write operation, for example, the data being written may be lost, leading to data loss.
  3. Reduced performance: Network issues can cause slow data transfer speeds, resulting in reduced performance of the NAS device. This can impact the time it takes to access or retrieve data from the device, affecting overall productivity.
  4. Inaccessibility: If the network connection to the NAS device is completely lost due to network issues, the data stored on the device may become temporarily or permanently inaccessible to connected clients. This can disrupt workflows and cause downtime for users relying on the data.
  5. Security vulnerabilities: Network issues can also expose the NAS device to security vulnerabilities. For example, if there are network misconfigurations or weak network security measures, unauthorized access to the NAS device may occur, leading to data breaches or unauthorized modifications to the stored data.

To mitigate these impacts, it is important to ensure a stable and reliable network infrastructure, regularly backup data, implement appropriate security measures, and monitor the network and NAS device for any potential issues.

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

Although NAS EonStor GS 2016 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.

  • 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 Infortrend EonStor GS 2016 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.
