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 a failed RAID rebuild process lead to data loss on NAS Digiever DS-16342-RM Pro+ devices?

Yes, a failed RAID rebuild process can potentially lead to data loss on NAS Digiever DS-16342-RM Pro+ devices. During a RAID rebuild, the system attempts to restore data on a failed or replaced hard drive by reconstructing it from the remaining drives in the array. If the rebuild process fails or encounters errors, it can result in data corruption or loss.

To minimize the risk of data loss during a RAID rebuild, it is important to ensure that the NAS device is properly configured and maintained. This includes regularly backing up critical data, monitoring the health of the drives, and addressing any issues promptly. It is also recommended to consult the manufacturer's documentation or seek professional assistance if you encounter any problems during the rebuild process.

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

Although NAS DS-16342-RM 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:

  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 Digiever DS-16342-RM 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:

  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 Digiever DS-16342-RM 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.

    Can data recovery from a NAS Digiever DS-16342-RM Pro+ device be performed if there are issues with the network router or switch?
    • Hetman Software
      Hetman Software 23.08.2023 13:59 #

      Yes, data recovery from a NAS Digiever DS-16342-RM Pro+ device can still be performed even if there are issues with the network router or switch. The NAS device itself stores the data on its hard drives, and as long as the drives are functioning properly, the data can still be recovered.

      In such cases, the data recovery process can be performed by directly connecting the NAS device to a computer or another device using an Ethernet cable. This allows for a direct connection without relying on the network router or switch.

      However, if the issues with the network router or switch are causing the NAS device to malfunction or if the drives themselves are damaged, then data recovery may require additional troubleshooting or professional assistance.
