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.

Are there any guidelines for configuring security settings on NAS Raidon Mobile Rack iR2777 devices to prevent unauthorized access and potential data loss?

Yes, there are several guidelines you can follow to configure security settings on NAS Raidon Mobile Rack iR2777 devices and prevent unauthorized access and potential data loss. Here are some recommendations:

1. Change Default Passwords: Start by changing the default login credentials for your NAS device. Use a strong and unique password that includes a combination of uppercase and lowercase letters, numbers, and special characters.
2. Enable Two-Factor Authentication (2FA): Implement two-factor authentication to add an extra layer of security. This will require users to provide a second form of verification, such as a code sent to their mobile device, in addition to their password.
3. Update Firmware: Regularly check for firmware updates provided by the manufacturer and apply them promptly. These updates often include security patches and bug fixes that can help protect against vulnerabilities.
4. Network Segmentation: Consider placing your NAS device on a separate network segment or VLAN (Virtual Local Area Network) to isolate it from other devices on your network. This can help prevent unauthorized access to the NAS device through compromised devices on the same network.
5. Disable Unnecessary Services: Disable any unnecessary services or protocols on the NAS device that are not required for its intended use. This reduces the attack surface and minimizes potential vulnerabilities.
6. Use Firewall and Intrusion Detection/Prevention Systems: Configure your network firewall to only allow necessary incoming and outgoing traffic to the NAS device. Additionally, consider implementing an Intrusion Detection/Prevention System (IDS/IPS) to monitor and block any suspicious network activity.
7. Regularly Backup Data: Implement a regular backup strategy to ensure that your data is securely backed up. This will help mitigate the risk of data loss in case of unauthorized access or hardware failure.
8. User Access Controls: Create individual user accounts for each person who needs access to the NAS device. Assign appropriate access permissions based on their roles and responsibilities. Restrict access to sensitive data to only authorized users.
9. Encryption: Enable encryption on your NAS device to protect data at rest. This ensures that even if the physical device is stolen, the data remains encrypted and inaccessible to unauthorized individuals.
10. Physical Security: Lastly, ensure that the NAS device is physically secured in a locked cabinet or room to prevent unauthorized physical access.

Remember, these guidelines are general recommendations, and it's always important to consult the user manual and documentation provided by the manufacturer for specific instructions on configuring security settings for your NAS Raidon Mobile Rack iR2777 device.

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

Although the NAS Mobile Rack iR2777 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 Mobile Rack iR2777. 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 iR2777 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 Mobile Rack iR2777 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.
