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 D-Link 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.

Are there any compatibility issues or limitations when connecting NAS D-Link DNS-6040M devices to different operating systems or platforms?

When connecting D-Link DNS-6040M NAS devices to different operating systems or platforms, there may be some compatibility issues or limitations to consider:

File System Compatibility: The D-Link DNS-6040M NAS device typically supports multiple file systems such as NTFS, FAT32, HFS+, and exFAT. However, certain operating systems may have limitations or lack support for specific file systems. For example, Windows-based systems may not natively support HFS+ (Mac OS Extended) file system, requiring additional software or drivers to access the NAS.
Network Protocol Support: The DNS-6040M NAS device supports various network protocols like SMB/CIFS, AFP, FTP, and NFS. While most operating systems provide support for standard protocols like SMB/CIFS, AFP (Apple Filing Protocol) may have limited support on non-Apple platforms. Similarly, NFS (Network File System) support may vary across different operating systems.
Software and Firmware Updates: The compatibility of the NAS device may depend on the software or firmware version it runs. It is essential to check for updates and ensure that the device firmware is up to date to ensure compatibility with the latest operating systems or platforms.
Third-Party Applications: Some NAS devices, including the DNS-6040M, offer additional features and functionality through third-party applications or add-ons. The availability and compatibility of these applications may vary across different operating systems or platforms. It is recommended to check the compatibility of specific applications with the intended operating system before installation.
User Interface: The DNS-6040M NAS device typically provides a web-based user interface for configuration and management. While this interface is usually accessible from any operating system or platform with a compatible web browser, there may be slight differences in the user experience or interface responsiveness across different systems.

To ensure compatibility and avoid limitations, it is advisable to consult the product documentation, check for any specific compatibility requirements or recommendations, and verify the compatibility with the intended operating system or platform before purchasing or connecting the D-Link DNS-6040M NAS device.

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

Although the NAS DNS-6040M 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.
