Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Infortrend often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Can device firmware rollback or downgrading impact data loss risks for NAS Infortrend EonStor CS 3024G devices?

Rolling back or downgrading the firmware of a NAS device like the Infortrend EonStor CS 3024G can potentially increase the risk of data loss. Firmware updates often include bug fixes, security patches, and performance improvements, so reverting to an older version may reintroduce known issues or vulnerabilities.

However, the actual impact on data loss risks depends on various factors, including the specific firmware versions involved, the existing configuration and data on the NAS, and the rollback process itself. It is crucial to carefully consider the potential consequences and consult with the device manufacturer or technical support before attempting any firmware rollback.

To mitigate the risk of data loss, it is recommended to ensure you have a backup of all critical data before performing any firmware updates or downgrades. This way, even if something goes wrong during the process, you can restore your data from the backup. Additionally, following best practices for data management, such as regular backups, redundant storage, and proper security measures, can help minimize the impact of any potential data loss risks.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS EonStor CS 3024G can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

Power off the NAS and disconnect it from the power source.

WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.
Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.
Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.
Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.
