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

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 take hard disks out of the NAS and connect them to a PC?

Although NAS DFS-4164 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

Turn off the storage and disconnect it from the power supply.

WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.
Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

Overwriting during the recovery process;
Loss resulting from bad sectors;
User mistakes.

To create an image, do the following:

Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files 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.
