Why Regular Data Recovery Tools Can’t Restore Files from RAID
Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.
This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.
Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Infortrend often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.
Can insufficient power supply or voltage fluctuations cause data loss on NAS Infortrend EonStor GS 3024 devices?
Insufficient power supply or voltage fluctuations can potentially cause data loss on any electronic device, including NAS (Network Attached Storage) devices like the Infortrend EonStor GS 3024. When a NAS device experiences power supply issues or voltage fluctuations, it can lead to various problems that may result in data loss, such as:
- Sudden power loss: If the power supply is insufficient or experiences fluctuations, it can cause the NAS device to shut down abruptly. This sudden power loss can interrupt ongoing read/write operations and corrupt data.
- Hard drive damage: Voltage fluctuations can damage the internal components of the NAS, including the hard drives. This damage can result in data loss or even complete drive failure.
- File system corruption: Power supply issues can cause the file system on the NAS to become corrupted. This corruption can make the data inaccessible or result in data loss.
To mitigate the risk of data loss due to power supply issues or voltage fluctuations, it is recommended to:
- Use a high-quality power supply that matches the requirements of the NAS device.
- Install an uninterruptible power supply (UPS) to provide backup power during power outages or fluctuations.
- Ensure that the NAS device is properly grounded to minimize the risk of electrical damage.
- Regularly backup important data from the NAS to an external storage device or cloud storage.
- Consider implementing redundancy in the NAS setup, such as RAID configurations, to protect against data loss in case of drive failures.
It is important to note that while taking precautions can reduce the risk of data loss, unforeseen circumstances or severe power supply issues may still lead to data loss. Therefore, it is always recommended to have a robust backup strategy in place to protect your data.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS EonStor GS 3024 can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:
-
Power off the NAS and disconnect it from the power source.
WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.
-
Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.
-
Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.
-
Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with Infortrend EonStor GS 3024. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.
How to recover data from a Infortrend
EonStor GS 3024 has 24 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- RAID 6;
- RAID 50;
- RAID 60;
- JBOD;
NAS supports:
- exFAT, VFAT, FAT 12 / 16 / 32;
- NTFS / ReFS;
- APFS / HFS+;
- Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
- VMFS / HikvisionFS;
How to Safely Recover Data from Disk Images
This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:
- Overwriting during the recovery process;
- Additional data loss caused by bad sectors;
- User errors.
To create a disk image, follow these steps:
-
Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
-
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
-
When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

-
Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

Where Are the User’s Files Actually Stored?
The Infortrend EonStor GS 3024 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.
