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 Qsan also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Can the use of specific encryption algorithms or protocols impact data loss risks on NAS Qsan XCubeNAS XN7012RE devices?

Yes, the use of specific encryption algorithms or protocols can impact data loss risks on NAS Qsan XCubeNAS XN7012RE devices. Encryption algorithms and protocols are used to secure data by converting it into unreadable format, making it difficult for unauthorized individuals to access or decipher the data.

By using strong encryption algorithms and protocols, such as AES (Advanced Encryption Standard) or SSL/TLS (Secure Sockets Layer/Transport Layer Security), the data stored on the NAS device can be protected from unauthorized access or interception. This can significantly reduce the risk of data loss due to unauthorized access, data breaches, or data theft.

Additionally, encryption can also provide protection against data loss in case of physical theft or loss of the NAS device itself. If the encrypted data falls into the wrong hands, it would be extremely difficult for them to access or use the data without the encryption keys.

It's important to note that while encryption can enhance data security and reduce data loss risks, it is not a foolproof solution. Other security measures, such as strong access controls, regular backups, and proper security configurations, should also be implemented to ensure comprehensive data protection on NAS devices.

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

Although NAS XCubeNAS XN7012RE 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.
