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 regular data verification or checksum processes help maintain data integrity on NAS Raidon InTANK iR2024 devices?

Regular data verification or checksum processes can help maintain data integrity on NAS Raidon InTANK iR2024 devices by ensuring that the data stored on the device remains intact and free from errors. Here are some ways these processes can help:

1. Detecting data corruption: Regular data verification processes involve checking the stored data against a reference value or checksum. If the calculated checksum does not match the expected value, it indicates that the data has been corrupted. By regularly performing these checks, any data corruption can be detected early, allowing for prompt action to be taken.
2. Preventing silent data corruption: Silent data corruption refers to errors that occur during data storage or transmission without being detected by the system. By implementing regular data verification processes, the integrity of the data can be continuously monitored, minimizing the risk of silent data corruption going unnoticed.
3. Identifying failing drives: RAID systems like the NAS Raidon InTANK iR2024 utilize multiple drives to store data redundantly. Regular data verification processes can help identify failing drives by detecting inconsistencies in the data stored across the drives. This allows for proactive replacement of faulty drives before complete failure occurs, preventing data loss.
4. Maintaining data consistency: Data verification processes ensure that the data stored on the NAS device remains consistent over time. By periodically checking the integrity of the data, any inconsistencies or errors can be identified and corrected, ensuring that the data remains reliable and accurate.
5. Enhancing data recovery: In the event of a data loss or corruption, regular data verification processes can aid in data recovery efforts. By having a reference checksum or verification mechanism in place, it becomes easier to identify and recover the correct data from backups or redundant storage.

Overall, regular data verification or checksum processes help maintain data integrity on NAS Raidon InTANK iR2024 devices by actively monitoring and detecting any potential issues, promoting data consistency, and aiding in data recovery efforts.

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

Although NAS InTANK iR2024 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 iR2024. 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 iR2024 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 iR2024 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.
