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 Thecus 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 use of specific file-sharing protocols impact data loss risks on NAS Thecus N4800 devices?

The use of specific file-sharing protocols can have an impact on data loss risks on NAS Thecus N4800 devices in the following ways:

Security vulnerabilities: Different file-sharing protocols have varying levels of security. Some protocols may have known vulnerabilities that can be exploited by attackers to gain unauthorized access to the NAS device and potentially cause data loss. It is important to choose protocols that have strong security measures in place to minimize the risk of data loss.
Encryption: File-sharing protocols that support encryption can help protect data during transit. Encryption ensures that even if the data is intercepted, it cannot be easily understood or accessed by unauthorized individuals. Choosing protocols that support encryption can significantly reduce the risk of data loss.
User authentication and access control: Some file-sharing protocols offer robust user authentication and access control mechanisms. These protocols allow administrators to define user permissions and restrict access to specific files or folders. By implementing strict access controls, the risk of accidental or intentional data loss due to unauthorized access can be minimized.
Data integrity checks: Certain file-sharing protocols include features that verify the integrity of the transferred data. These protocols can detect and correct any errors or inconsistencies in the data, reducing the risk of data loss due to corrupted files.
Backup and versioning support: Some file-sharing protocols provide built-in backup and versioning support, allowing users to easily create backups of their data and restore previous versions if needed. This can be crucial in mitigating the impact of data loss events, as it provides an additional layer of protection against accidental deletions or data corruption.

Overall, choosing file-sharing protocols that prioritize security, encryption, access control, data integrity, and backup support can significantly reduce the risks of data loss on NAS Thecus N4800 devices. It is essential to carefully evaluate and select protocols that align with the specific security requirements and data protection needs of the organization.

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

Although NAS N4800 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.
