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

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.
