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.

Are there any compatibility issues or limitations when connecting NAS Digiever DS-4009 devices to different operating systems or platforms?

The Digiever DS-4009 NAS devices are designed to be compatible with various operating systems and platforms. They support Windows, Mac, and Linux operating systems, allowing users to easily connect and access the NAS from different devices.

However, it is important to note that certain features or functionalities may have limitations or compatibility issues depending on the operating system or platform being used. For example, specific software or applications provided by Digiever may have limited support for certain operating systems.

It is recommended to check the Digiever website or contact their support team for detailed information on compatibility and any potential limitations when connecting the DS-4009 NAS devices to different operating systems or platforms.

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

Although the NAS DS-4009 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:

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

Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
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.
Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

Where Are the User’s Files Actually Stored?

The Digiever DS-4009 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.

  Data recovery from a NAS device like Digiever DS-4009 can be challenging if the device is experiencing intermittent connectivity issues. The success of data recovery depends on the extent of the connectivity issues and the underlying cause.
  If the connectivity issues are due to network problems or temporary interruptions, it might be possible to recover the data by resolving the connectivity problems and accessing the device normally. In such cases, it is recommended to troubleshoot the network issues and ensure a stable connection before attempting data recovery.
  However, if the connectivity issues are caused by hardware failures or more severe problems with the NAS device, data recovery becomes more complex. In such cases, it is advisable to contact a professional data recovery service provider who specializes in NAS devices. They have the expertise and specialized tools to deal with complex data recovery scenarios and can attempt to recover the data even from devices experiencing connectivity issues.
  It is important to note that attempting data recovery on your own without proper knowledge and tools can potentially worsen the situation and lead to permanent data loss. Therefore, it is always recommended to seek professional assistance for data recovery from a NAS device.
