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.
How can network issues impact the data stored on NAS Raidon InTANK iR2024S devices?
Network issues can impact the data stored on NAS Raidon InTANK iR2024S devices in several ways:
- Slow data transfer: Network issues such as high latency, packet loss, or network congestion can result in slow data transfer speeds between the NAS device and the connected devices. This can lead to longer backup or file transfer times, affecting productivity and efficiency.
- Data corruption: Network issues like unstable connections or intermittent disconnections can cause data corruption during file transfers. If the data is not transferred properly or gets interrupted midway, it can result in incomplete or corrupted files on the NAS device.
- Inaccessibility: Network issues can make the NAS device inaccessible to connected devices. If the network connection is lost or unstable, users may not be able to access the data stored on the NAS, leading to downtime and disruption in workflow.
- Data loss: In extreme cases, network issues can cause data loss on the NAS device. If there are frequent network interruptions or failures, it can result in the loss of important data that was being written or transferred to the NAS.
- Security risks: Network issues can also expose the NAS device to security risks. If there are vulnerabilities in the network infrastructure or if the network is compromised, unauthorized access or attacks on the NAS device can lead to data breaches or loss.
To mitigate these impacts, it is important to ensure a stable and reliable network infrastructure, regularly backup data from the NAS device to an offsite location, implement security measures like firewalls and access controls, and monitor the network for any potential issues or anomalies.
How to take hard disks out of the NAS and connect them to a PC?
Although NAS InTANK iR2024S 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 iR2024S. 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 iR2024S 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 InTANK iR2024S 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.

The NAS Raidon InTANK iR2024S devices use a RAID (Redundant Array of Independent Disks) configuration for data storage. RAID technology combines multiple physical hard drives into a single logical unit to provide improved performance, fault tolerance, and data redundancy.
The specific RAID level used in the InTANK iR2024S is not explicitly mentioned in the available information. However, it is likely that it supports various RAID levels such as RAID 0, RAID 1, RAID 5, RAID 6, or RAID 10.
The choice of RAID level can affect data recovery in the following ways:
In general, RAID configurations with higher levels of redundancy (such as RAID 1, RAID 6, or RAID 10) offer better data recovery options in case of drive failures. However, it is always recommended to have regular backups to mitigate the risk of data loss.
