How to recover data from Infortrend EonStor DS 4024B 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 Infortrend EonStor DS 4024B

Infortrend EonStor DS 4024B 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 DS 4024B.

How to recover data from NAS Infortrend EonStor DS 4024B

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.

Can excessive drive spin-down or power-saving settings impact data retrieval in case of failure on NAS Infortrend EonStor DS 4024B devices?

Excessive drive spin-down or power-saving settings can potentially impact data retrieval in case of failure on NAS Infortrend EonStor DS 4024B devices.

When drives are set to spin down frequently or aggressively, it may take longer for the drives to spin up and become ready for data retrieval. This can increase the latency and response time when accessing data, especially if multiple drives need to spin up simultaneously.

In addition, power-saving settings that put the drives into a low-power mode can also affect data retrieval. In such modes, the drives may take longer to respond to read or write requests, leading to slower performance and potential data retrieval issues.

Furthermore, if a drive fails and needs to be replaced, excessive spin-down or power-saving settings can cause delays in detecting the failure and initiating the rebuild process. This can prolong the time it takes to restore data redundancy and increase the risk of data loss during this period.

To mitigate these potential issues, it is recommended to configure drive spin-down and power-saving settings appropriately based on the specific requirements and usage patterns of the NAS device. It is important to strike a balance between power-saving and performance to ensure optimal data retrieval and system reliability.

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

Although NAS EonStor DS 4024B 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 Infortrend EonStor DS 4024B 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.
