How to recover data from Idis DR-6116P NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Idis DR-6116P

Idis DR-6116P NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from DR-6116P.

How to recover data from NAS Idis DR-6116P

Recover data from damaged RAID arrays inaccessible from a computer.

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 Idis 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 hardware upgrades or modifications lead to data loss if not properly executed on NAS Idis DR-6116P devices?

Yes, hardware upgrades or modifications can potentially lead to data loss if not properly executed on NAS Idis DR-6116P devices. If the hardware upgrade or modification involves changing components such as hard drives, memory modules, or other critical hardware components, there is a risk of data loss if the process is not done correctly.

For example, if the hard drives are not properly connected or configured during an upgrade, it could result in data not being accessible or even being overwritten. Similarly, if the memory modules are not compatible or installed correctly, it could lead to system instability or data corruption.

It is crucial to follow the manufacturer's guidelines and instructions when performing any hardware upgrades or modifications on NAS devices. Additionally, it is recommended to backup all important data before attempting any hardware changes to mitigate the risk of data loss.

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

Although NAS DR-6116P 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.

DR-6116P has 6 HDD slots, and it supports the following array types:

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

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • 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 Idis DR-6116P 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.

    Are there any specific recovery methods for NAS Idis DR-6116P devices with striped or mirrored data configurations?

      Yes, there are specific recovery methods for NAS Idis DR-6116P devices with striped or mirrored data configurations. Here are some general steps that can be followed:

      1. Identify the type of RAID configuration used in the NAS device (striped or mirrored).
      2. If the NAS device uses a striped (RAID 0) configuration, recovery becomes more complex as data is split across multiple drives. In such cases, it is recommended to contact a professional data recovery service that specializes in RAID recovery. They will have the necessary tools and expertise to recover data from striped configurations.
      3. If the NAS device uses a mirrored (RAID 1) configuration, recovery is relatively simpler. In a mirrored configuration, data is duplicated on multiple drives, providing redundancy. If one drive fails, the data can still be accessed from the other drive. To recover data from a failed drive in a mirrored configuration, follow these steps:

      a. Identify the failed drive in the NAS device.

      b. Replace the failed drive with a new, identical drive. Ensure that the replacement drive is of the same capacity or larger.

      c. The NAS device should automatically start rebuilding the mirrored array using the new drive. This process may take some time, depending on the amount of data and the performance of the NAS device.

      d. Once the rebuild is complete, the NAS device should be fully operational, and data can be accessed as before.

      It is important to note that these steps are general guidelines, and the specific recovery process may vary depending on the NAS device and its firmware. It is always recommended to consult the user manual or contact the manufacturer for detailed recovery instructions specific to the NAS Idis DR-6116P device.
