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 iR8777 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 iR8777 devices to prevent unauthorized access and potential data loss. Here are some recommendations:

1. Change Default Passwords: When setting up the device, make sure to change the default passwords for both the admin account and any user accounts. Use strong passwords that are not easily guessable.
2. Enable Firewall: Enable the built-in firewall on the device to restrict access to only necessary services and ports. Configure the firewall to block all incoming connections except for the ones required for remote access or specific services.
3. Disable Unused Services: Disable any unnecessary services or protocols on the device to reduce the attack surface. Only enable the services that are required for your specific use case.
4. Regularly Update Firmware: Keep the device's firmware up to date by regularly checking for updates provided by the manufacturer. Firmware updates often include security patches and bug fixes that can help protect against potential vulnerabilities.
5. Enable Access Control: Utilize access control features provided by the device to restrict access to specific users or IP addresses. Only allow trusted users or devices to access the NAS.
6. Implement User Authentication: Enable user authentication mechanisms such as two-factor authentication (2FA) or LDAP integration to add an extra layer of security. This ensures that only authorized users can access the device.
7. Regularly Backup Data: Implement a regular backup strategy to ensure that your data is protected even in the event of unauthorized access or data loss. Store backups in a separate location or on a different device to mitigate the risk of data loss.
8. Monitor and Log Activity: Enable logging and monitoring features on the device to track any suspicious activities or unauthorized access attempts. Regularly review the logs to identify any security issues and take appropriate actions.
9. Physically Secure the Device: Ensure that the NAS device is physically secured in a locked cabinet or room to prevent unauthorized physical access.

It is important to note that these guidelines are general recommendations, and it is always recommended to consult the device's user manual or contact the manufacturer for specific instructions and best practices for your NAS Raidon Mobile Rack iR8777 device.

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

Although the NAS Mobile Rack iR8777 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 iR8777. 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 iR8777 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 iR8777 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.
