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 Raidon 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 encryption safeguard data stored on NAS Raidon InTANK iR2623-S3 devices?
Yes, encryption can safeguard data stored on NAS Raidon InTANK iR2623-S3 devices. Encryption is the process of encoding data in a way that only authorized parties can access it. By encrypting the data stored on the NAS device, even if someone gains unauthorized access to the physical device or the data is stolen, they will not be able to read or use the encrypted data without the decryption key. This adds an extra layer of security to protect sensitive information.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS InTANK iR2623-S3 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 Raidon InTANK iR2623-S3. 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 Raidon
InTANK iR2623-S3 has 3 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- JBOD;
NAS supports:
- APFS / HFS+;
- Ext2 / Ext3 / Ext4;
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 Raidon InTANK iR2623-S3 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.

If the storage disks in a NAS Raidon InTANK iR2623-S3 device have been physically disconnected or damaged, it may still be possible to recover the data, but it can be challenging and may require professional data recovery services.
Here are a few potential steps to consider:
It is important to note that data recovery from physically damaged disks can be expensive and there is no guarantee of success. Therefore, it is always recommended to have regular backups of important data to avoid such situations.
