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 Actidata 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 improper shutdown or unclean system reboots lead to data loss on NAS Actidata actiNAS XL 1U-4 devices?

Improper shutdown or unclean system reboots can potentially lead to data loss on any storage device, including NAS (Network Attached Storage) devices like the Actidata actiNAS XL 1U-4.

When a system is shut down improperly or rebooted unexpectedly, it can interrupt ongoing read or write operations, causing data corruption or incomplete data writes. This can lead to files becoming inaccessible or even completely lost.

To minimize the risk of data loss, it is important to follow proper shutdown procedures and ensure that all active processes or file transfers are completed before shutting down or rebooting the NAS device. Additionally, regularly backing up important data to an external storage device or cloud service is recommended as an extra precautionary measure.

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

Although NAS actiNAS XL 1U-4 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:

  1. 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.

  2. 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.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Actidata actiNAS XL 1U-4. 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.

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • RAID 50;
  • RAID 60;
  • JBOD;

NAS supports:

  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
  • VMFS / HikvisionFS;

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:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. 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.

Where are user’s files stored?

The Actidata actiNAS XL 1U-4 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.
