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 the NAS Raidon InTANK iR8024 device's CPU or processing power affect data transfer and potential loss?

The NAS Raidon InTANK iR8024 device's CPU or processing power can affect data transfer and potential data loss in the following ways:

1. Data Transfer Speed: The CPU's processing power determines the device's ability to handle multiple data requests and perform various tasks simultaneously. A more powerful CPU can handle data transfer requests faster, resulting in quicker data transfer speeds and improved performance. Conversely, a weaker CPU may struggle to handle multiple requests, leading to slower data transfer speeds.
2. Data Integrity: The CPU plays a crucial role in data integrity during data transfer. It is responsible for various tasks like error correction, data verification, and encryption/decryption. A powerful CPU can efficiently handle these tasks, ensuring data integrity during transfer. In contrast, a weaker CPU may struggle to perform these tasks accurately, increasing the risk of data corruption or loss during transfer.
3. RAID Performance: The NAS Raidon InTANK iR8024 device often utilizes RAID (Redundant Array of Independent Disks) technology to improve data redundancy and performance. The CPU's processing power affects the performance of the RAID system. A more powerful CPU can efficiently handle the complex calculations and data distribution required by RAID, resulting in better overall performance. A weaker CPU may lead to degraded RAID performance, affecting data transfer speed and potentially increasing the risk of data loss.
4. Data Recovery: In case of a data loss event or disk failure, the CPU's processing power is essential for data recovery processes. It is responsible for reconstructing the lost or damaged data from the remaining disks in the RAID array. A powerful CPU can perform these calculations quickly, reducing the time required for data recovery. However, a weaker CPU may prolong the recovery process, increasing the risk of permanent data loss or extended downtime.

Overall, a more powerful CPU in the NAS Raidon InTANK iR8024 device can positively impact data transfer speed, data integrity, RAID performance, and data recovery processes, reducing the potential for data loss.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS InTANK iR8024 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:

1. 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.

2. 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.

3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

4. 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.

   How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Raidon InTANK iR8024. 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 iR8024 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:

1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

2. Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.

3. 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.

   

4. 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 iR8024 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.
