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 elevation of privileges or compromised user accounts lead to data loss or unauthorized access on NAS Digiever DS-8220-SRM Pro+ devices?

Yes, elevation of privileges or compromised user accounts can potentially lead to data loss or unauthorized access on NAS Digiever DS-8220-SRM Pro+ devices. If an attacker gains elevated privileges or compromises a user account with administrative access, they may be able to bypass security measures or manipulate settings on the device, potentially resulting in data loss or unauthorized access to sensitive information stored on the NAS device. It is important to ensure that proper security measures, such as strong passwords, access controls, and regular firmware updates, are in place to mitigate these risks.

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

Although NAS DS-8220-SRM Pro+ 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.

How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Digiever DS-8220-SRM Pro+. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

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 DS-8220-SRM Pro+ 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.

  Recovering data from a NAS device that has been affected by a controller card failure or interface problem can be challenging. However, it is possible to recover data in some cases. Here are a few steps you can try:
  Check for physical issues: Ensure that all cables are properly connected and there are no loose connections. Sometimes, a loose cable can cause the interface problem.
  Replace the controller card: If the controller card has failed, you may need to replace it with a new one. Consult the manufacturer or a professional technician to ensure compatibility and proper installation.
  Seek professional help: If the above steps do not work, it is recommended to contact a professional data recovery service. They have specialized tools and expertise to recover data from faulty NAS devices. However, keep in mind that professional data recovery services can be expensive.
  Remember to always have a backup of your important data to avoid such situations in the future.
