How to recover data from Infortrend EonStor CS 4024G 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 4024G

Infortrend EonStor CS 4024G 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 4024G.

How to recover data from NAS Infortrend EonStor CS 4024G

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 a failed RAID rebuild process lead to data loss on NAS Infortrend EonStor CS 4024G devices?

Yes, a failed RAID rebuild process can potentially lead to data loss on NAS Infortrend EonStor CS 4024G devices. During a RAID rebuild, the device is reconstructing data from the remaining drives in the array to replace the failed drive. If there are any issues or errors during this process, it can result in data corruption or loss.

It is important to ensure that the RAID rebuild process is properly monitored and any errors or issues are addressed promptly. Regular backups of important data are also crucial to mitigate the risk of data loss in case of a failed rebuild or any other unforeseen circumstances.

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

Although NAS EonStor CS 4024G 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 4024G 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.

      Data recovery from a NAS device like the Infortrend EonStor CS 4024G can be challenging if the disks have been reformatted. Reformatting usually involves erasing the file system and directory structure, making it difficult to recover data using conventional methods.

      However, it may still be possible to recover some or all of the data by using specialized data recovery software or services. These tools can scan the disk for remnants of the old data and attempt to reconstruct the file system and recover the files.

      It is important to note that the success of data recovery depends on various factors, such as the extent of the reformatting, the usage of the device after reformatting, and the availability of any backups. It is recommended to consult with a professional data recovery service that specializes in NAS devices for the best chance of recovering your data.

    Note: It is important to ensure that all devices have proper network connectivity and access to the shared folder on the NAS for smooth playback and synchronization.

  • Are there any limitations or restrictions when using iTunes on the Infortrend EonStor CS 4024G NAS, such as file format compatibility, maximum library size, or concurrent user limitations?

    The Infortrend EonStor CS 4024G NAS is a hardware storage device and does not directly dictate limitations or restrictions related to iTunes usage. However, there are general limitations and restrictions that apply to iTunes regardless of the storage device being used. Here are some common limitations:

    1. File format compatibility: iTunes supports a wide range of audio and video file formats, including MP3, AAC, WAV, AIFF, and more. However, some uncommon or proprietary formats may not be compatible with iTunes.
    2. Maximum library size: iTunes does not have a fixed maximum library size. However, the performance of iTunes may degrade as the library grows larger, especially if it includes a large number of media files. It is recommended to keep the library size manageable to ensure smooth performance.
    3. Concurrent user limitations: iTunes does not have a built-in feature for concurrent user access control. By default, iTunes is designed for single-user access. However, you can share your iTunes library over a network using Home Sharing or by storing the library on a network share. In such cases, the limitations on concurrent user access would depend on the network share and its associated permissions.

    It's important to note that the Infortrend EonStor CS 4024G NAS is primarily designed for storage purposes and does not provide any specific integrations or optimizations for iTunes. It serves as a storage repository for your iTunes library, and the limitations or restrictions mentioned above are more related to the iTunes software itself rather than the NAS device.
