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.

How can regular data verification or checksum processes help maintain data integrity on NAS Raidon InTANK iR2025 devices?

Regular data verification or checksum processes can help maintain data integrity on NAS Raidon InTANK iR2025 devices in the following ways:

1. Detecting Data Corruption: Data verification processes involve comparing the data stored on the NAS device with a known checksum value. By regularly running these processes, any data corruption or bit errors can be detected. If the checksum value doesn't match, it indicates that the data has been altered or corrupted.
2. Identifying Disk Failures: RAID (Redundant Array of Independent Disks) systems like the InTANK iR2025 utilize multiple disks for data redundancy and improved performance. Regular data verification can help identify disk failures by comparing the data across all disks. If the data on one disk differs from the others, it may indicate a failing or faulty disk that needs to be replaced.
3. Preventing Silent Data Corruption: Silent data corruption refers to the scenario where data gets corrupted without any immediate indication or error message. By using checksum processes, the NAS device can periodically verify the integrity of data and identify silent corruption issues. This allows for timely intervention and data restoration from backups before the corrupted data causes significant problems.
4. Ensuring Data Consistency: NAS devices like the InTANK iR2025 support various data access protocols, including NFS, SMB, and iSCSI. Regular data verification processes help ensure that the data accessed through these protocols remains consistent and intact. It prevents any unauthorized modifications, accidental changes, or data tampering.
5. Enhancing Data Recovery: In the event of a disk failure or data corruption, regular data verification processes can help with data recovery. By identifying the corrupted or mismatched data, it becomes easier to restore the correct data from backups or rebuild the RAID array using redundancy information.

Overall, regular data verification or checksum processes on NAS Raidon InTANK iR2025 devices help in maintaining data integrity, identifying disk failures, preventing silent data corruption, ensuring data consistency, and enhancing data recovery capabilities.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS InTANK iR2025 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:

1. 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.

2. 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.

3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

4. 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.

   How to Order Remote Data Recovery

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with Raidon InTANK iR2025. 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 iR2025 has 2 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• 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:

1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

3. 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.

   

4. 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 iR2025 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.
