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 Digiever 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 encryption safeguard data stored on NAS Digiever DFS-4164 devices?

Yes, encryption can safeguard data stored on NAS Digiever DFS-4164 devices. The Digiever DFS-4164 devices support various encryption methods, such as AES 256-bit encryption, to protect the data stored on the NAS. This encryption ensures that even if unauthorized access occurs, the data remains encrypted and unreadable without the proper encryption key. It adds an extra layer of security to prevent data breaches and unauthorized access to sensitive information stored on the NAS device.

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

Although the NAS DFS-4164 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.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

Overwriting during the recovery process;
Additional data loss caused by bad sectors;
User errors.

To create a disk image, follow these steps:

Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.
Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

Where Are the User’s Files Actually Stored?

The Digiever DFS-4164 network-attached storage keeps OS Linux operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

  It is possible to recover data from a physically damaged NAS Digiever DFS-4164 device, but it can be challenging and may require the assistance of a professional data recovery service.
  Here are a few steps you can take to attempt data recovery from a physically damaged NAS device:
  Assess the damage: Determine the extent of the physical damage to the device. If the damage is severe, such as a broken or damaged circuit board, it may require professional help.
  Replace damaged parts: If you have technical expertise, you may be able to replace damaged parts, such as the power supply or hard drives, with compatible components. This can potentially allow the device to power on and access the data.
  Connect the drives to another system: If the hard drives are undamaged, you can remove them from the damaged NAS device and connect them to another computer or NAS device to attempt data recovery. Ensure you use compatible connectors and take proper precautions to avoid further damage.
  Use data recovery software: Once the drives are connected to a working system, you can try using data recovery software to scan and recover data from the damaged drives. There are several data recovery software options available, both free and paid, that can help with this process.
  Seek professional help: If the above steps do not yield satisfactory results or if you are not comfortable performing the recovery yourself, it is recommended to seek the assistance of a professional data recovery service. They have specialized tools and expertise to deal with physically damaged devices and can increase the chances of successful data recovery.
  Remember, data recovery from physically damaged devices can be complex and success is not guaranteed. It is always advisable to have regular backups of your important data to avoid such situations.
