Why can’t ordinary software tools restore files from RAID?
Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.
Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.
Various RAID levels store information in different ways. Additionally, manufacturers like Raidon also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.
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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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 take hard disks out of the NAS and connect them to a PC?
Although NAS Mobile Rack iR2777 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:
-
Turn off the storage and disconnect it from the power supply.
WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.
-
Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.
-
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
-
Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Restoring data with Hetman RAID Recovery
This program recovers data from damaged RAID arrays and is fully compatible with Raidon Mobile Rack iR2777. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.
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;
Safe recovery from disk images
This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:
- Overwriting during the recovery process;
- Loss resulting from bad sectors;
- User mistakes.
To create an image, do the following:
-
Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
-
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
-
When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.
-
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.
Where are user’s files 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.

Yes, data recovery from a NAS Raidon Mobile Rack iR2777 device can still be performed even if there are issues with the motherboard or system board. In such cases, the data recovery process may involve removing the hard drives from the device and connecting them to another working system or using specialized data recovery equipment. This allows the data recovery professionals to access and recover the data from the individual hard drives, bypassing the faulty motherboard or system board.
