Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Idis often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

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 Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS DR-6116P can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually 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?
    • Hetman Software
      Hetman Software 26.08.2023 22:00 #

      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.
