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

Although the NAS DS-16342-RM Pro+ 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.

Step-by-Step Data Recovery with Hetman RAID Recovery

Hetman Raid Recovery

This program restores data from damaged RAID arrays and is fully compatible with Digiever DS-16342-RM Pro+. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.

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 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.
