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 iR8777 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 iR8777 devices to prevent unauthorized access and potential data loss. Here are some recommendations:

1. Change Default Passwords: When setting up the device, make sure to change the default passwords for both the admin account and any user accounts. Use strong passwords that are not easily guessable.
2. Enable Firewall: Enable the built-in firewall on the device to restrict access to only necessary services and ports. Configure the firewall to block all incoming connections except for the ones required for remote access or specific services.
3. Disable Unused Services: Disable any unnecessary services or protocols on the device to reduce the attack surface. Only enable the services that are required for your specific use case.
4. Regularly Update Firmware: Keep the device's firmware up to date by regularly checking for updates provided by the manufacturer. Firmware updates often include security patches and bug fixes that can help protect against potential vulnerabilities.
5. Enable Access Control: Utilize access control features provided by the device to restrict access to specific users or IP addresses. Only allow trusted users or devices to access the NAS.
6. Implement User Authentication: Enable user authentication mechanisms such as two-factor authentication (2FA) or LDAP integration to add an extra layer of security. This ensures that only authorized users can access the device.
7. Regularly Backup Data: Implement a regular backup strategy to ensure that your data is protected even in the event of unauthorized access or data loss. Store backups in a separate location or on a different device to mitigate the risk of data loss.
8. Monitor and Log Activity: Enable logging and monitoring features on the device to track any suspicious activities or unauthorized access attempts. Regularly review the logs to identify any security issues and take appropriate actions.
9. Physically Secure the Device: Ensure that the NAS device is physically secured in a locked cabinet or room to prevent unauthorized physical access.

It is important to note that these guidelines are general recommendations, and it is always recommended to consult the device's user manual or contact the manufacturer for specific instructions and best practices for your NAS Raidon Mobile Rack iR8777 device.

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

Although NAS Mobile Rack iR8777 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.

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Raidon Mobile Rack iR8777. 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 iR8777 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 Mobile Rack iR8777 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.
