How to recover data from Infortrend EonStor CS 4014U 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 CS 4014U

Infortrend EonStor CS 4014U 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 CS 4014U.

How to recover data from NAS Infortrend EonStor CS 4014U

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 regular data integrity checks help prevent data loss in NAS Infortrend EonStor CS 4014U devices?

Regular data integrity checks can help identify and prevent data loss in NAS devices like the Infortrend EonStor CS 4014U. These checks involve verifying the integrity of data stored on the device by comparing it to a known checksum or hash value. If the calculated checksum does not match the expected value, it indicates that the data has been altered or corrupted.

By regularly performing data integrity checks, you can proactively identify any inconsistencies or data corruption issues before they lead to data loss. This allows you to take appropriate actions, such as restoring data from backups or repairing the affected files, to prevent further data loss.

Additionally, it is important to ensure that the NAS device itself has built-in data protection mechanisms such as RAID (Redundant Array of Independent Disks), which can provide fault tolerance and redundancy to protect against hardware failures and minimize the risk of data loss.

However, it is worth noting that while regular data integrity checks can help prevent data loss, they are not a foolproof solution. It is crucial to have a comprehensive data backup strategy in place, including off-site backups, to ensure data recoverability in case of catastrophic events or unforeseen circumstances.

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

Although NAS EonStor CS 4014U 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 CS 4014U 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.
