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 InTANK iR8624 devices to prevent unauthorized access and potential data loss?
Yes, there are several guidelines you can follow to configure security settings on NAS Raidon InTANK iR8624 devices and prevent unauthorized access and potential data loss. Here are some recommendations:
- Change default credentials: Immediately change the default username and password provided by the manufacturer. Choose a strong, unique password that includes a combination of upper and lowercase letters, numbers, and special characters.
- Enable firewall: Activate the built-in firewall on the NAS device to restrict access from external networks. Configure the firewall to only allow necessary services and block all other incoming connections.
- 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 your device from vulnerabilities.
- Disable unnecessary services: Disable any unused or unnecessary services and protocols to reduce the attack surface. Only enable the services you actually need for your specific use case.
- Enable access controls: Utilize access control mechanisms provided by the NAS device, such as user accounts, groups, and permissions. Assign appropriate access rights to users and restrict access to sensitive data.
- Use strong encryption: Enable encryption for data stored on the NAS device. This ensures that even if someone gains unauthorized access to the physical device, they will not be able to read the encrypted data.
- Regular backups: Implement a regular backup strategy to ensure that your data is protected against potential loss or corruption. Store backups in a separate location or on a different device to safeguard against device failure or physical damage.
- Network segregation: Consider placing the NAS device on a separate network or VLAN to isolate it from other devices. This can help prevent unauthorized access and limit the potential impact of a security breach.
- Disable remote access if not needed: If remote access to the NAS device is not required, disable it completely. Remote access increases the attack surface and potential for unauthorized access.
- Monitor and log: Enable logging and monitoring features on the NAS device to track and identify any suspicious activities. Regularly review the logs to detect potential security incidents or unauthorized access attempts.
It is important to note that these guidelines provide a general overview, and the specific configuration steps may vary depending on the NAS device and its firmware version. Always refer to the manufacturer's documentation for detailed instructions and best practices.
How to take hard disks out of the NAS and connect them to a PC?
Although NAS InTANK iR8624 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 InTANK iR8624. 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.
How to recover data from a Raidon
InTANK iR8624 has 3 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- 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 InTANK iR8624 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.
