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 Digiever 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 device firmware rollback or downgrading impact data loss risks for NAS Digiever DS-8464-SRM Pro+ devices?

Rolling back or downgrading the firmware of a NAS device like the Digiever DS-8464-SRM Pro+ can potentially impact data loss risks. Here are a few considerations:

Compatibility: Before attempting a firmware rollback, ensure that the older firmware version is compatible with your NAS device model. Using an incompatible firmware version can lead to system instability or malfunction, potentially resulting in data loss.
Bug Fixes and Security Patches: Firmware updates often include bug fixes, performance improvements, and security patches. By rolling back to an older firmware version, you may lose these important updates, leaving your NAS device vulnerable to security threats or stability issues.
Data Corruption: If the firmware rollback process is not executed correctly, it can lead to data corruption or loss. It is crucial to follow the manufacturer's instructions precisely and ensure that you have a backup of your important data before attempting any firmware changes.
Unsupported Features: Newer firmware versions may introduce additional features or improvements that are not available in older versions. By downgrading the firmware, you may lose access to these features, impacting the functionality and usability of your NAS device.

To minimize the risks associated with firmware rollback, it is recommended to consult the manufacturer's documentation, seek support from their technical team, and backup all critical data before proceeding with any firmware changes.

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

Although NAS DS-8464-SRM Pro+ 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.
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.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
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.
