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 Thecus 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 the use of specific data synchronization or replication mechanisms mitigate data loss risks for NAS Thecus M3800 devices?

Yes, the use of specific data synchronization or replication mechanisms can help mitigate data loss risks for NAS Thecus M3800 devices. These mechanisms ensure that data is consistently and accurately replicated or synchronized between multiple devices or locations, reducing the chances of data loss.

Some common mechanisms that can be used include:

RAID (Redundant Array of Independent Disks): RAID technology combines multiple physical disks into a single logical unit, providing redundancy and fault tolerance. This helps protect against data loss in case of disk failures.
Snapshot Technology: Snapshot technology captures the state of data at a specific point in time. It allows you to revert to a previous snapshot if data is accidentally deleted or becomes corrupted.
Backup and Restore: Regularly backing up data to an external storage device or cloud service ensures that a copy of important data is always available. In case of data loss, you can restore the data from the backup.
Remote Replication: Remote replication involves replicating data from one NAS device to another located in a different physical location. This provides an additional layer of protection against data loss due to disasters or physical damage to the primary device.
Continuous Data Protection (CDP): CDP continuously captures and stores every change made to data, allowing you to restore to any point in time. This minimizes the risk of data loss as you can recover data from any previous state.

By implementing these mechanisms, you can significantly reduce the risk of data loss on NAS Thecus M3800 devices. It is important to regularly monitor and test the synchronization or replication processes to ensure their effectiveness.

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

Although the NAS M3800 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.
