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 the use of specific encryption algorithms or protocols impact data loss risks on NAS Raidon Mobile Rack iT1775C devices?
Yes, the use of specific encryption algorithms or protocols can impact data loss risks on NAS Raidon Mobile Rack iT1775C devices. Encryption algorithms and protocols are designed to protect data by converting it into a format that is unreadable without the appropriate decryption key. By using strong encryption algorithms and protocols, the risk of unauthorized access to the data stored on the device is reduced.
When selecting encryption algorithms or protocols, it is important to choose those that are widely recognized, tested, and considered secure. Some commonly used encryption algorithms include AES (Advanced Encryption Standard) and RSA (Rivest-Shamir-Adleman). These algorithms have undergone extensive scrutiny and are considered secure when implemented correctly.
Additionally, the strength of the encryption key used in conjunction with the algorithm or protocol is also crucial. Longer and more complex encryption keys are generally more secure and harder to crack. It is recommended to use keys that are at least 128 bits or longer for AES encryption.
Implementing encryption on NAS Raidon Mobile Rack iT1775C devices can significantly reduce the risk of data loss in case of theft, unauthorized access, or physical damage to the device. However, it is important to note that encryption alone cannot completely eliminate all data loss risks. Other factors such as proper backup strategies, secure access controls, and regular maintenance should also be considered to ensure data protection.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS Mobile Rack iT1775C 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 Mobile Rack iT1775C. 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
Mobile Rack iT1775C has 1 HDD slots, and it supports the following array types:
- 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 Mobile Rack iT1775C 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.

Recovering data from a physically damaged NAS Raidon Mobile Rack iT1775C device is technically possible, but it depends on the extent of the damage. If the damage is limited to the external casing or connectors, it may be possible to transfer the hard drives to another compatible enclosure or connect them directly to a computer to access the data.
However, if the internal components or hard drives themselves are damaged, the chances of data recovery become more challenging. In such cases, it is recommended to seek professional data recovery services from a reputable company that specializes in recovering data from physically damaged storage devices.
It's important to note that data recovery from physically damaged devices can be a complex and costly process, and there is no guarantee of success. It is always recommended to regularly backup important data to prevent data loss in case of physical damage or other failures.
