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 Overland Storage 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 the use of deduplication or compression technologies impact data loss risks on NAS Overland Storage SnapServer XSD 40 NAS devices?

Yes, the use of deduplication or compression technologies can impact data loss risks on NAS Overland Storage SnapServer XSD 40 NAS devices.

Deduplication technology eliminates redundant data by identifying and storing only unique data blocks. This can reduce the amount of data stored on the device, resulting in lower storage requirements and potentially reducing the risk of data loss. However, if the deduplication process is not implemented correctly or if there are errors in the deduplication algorithm, it could lead to data loss or corruption.

Compression technology reduces the size of data files by encoding them in a more efficient format. This can also reduce storage requirements and potentially lower the risk of data loss. However, if the compression algorithm used is not reliable or if there are errors in the compression process, it could result in data loss or corruption.

It is important to note that while deduplication and compression technologies can help reduce storage requirements and potentially lower the risk of data loss, they should be implemented carefully and with proper testing to ensure data integrity and minimize the chances of any adverse effects on the NAS device.

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

Although the NAS SnapServer XSD 40 NAS 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 Overland Storage SnapServer XSD 40 NAS 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.

      It is possible to recover data from a NAS device that has undergone a file system conversion or re-partitioning, but it can be challenging and may require professional data recovery services.

      When a file system conversion or re-partitioning is performed on a NAS device, the existing data may be overwritten or the file system structures may be modified, making it difficult to access the data using standard methods. However, specialized data recovery techniques can be used to analyze the device and recover the lost data.

      It is important to note that attempting data recovery on your own without proper knowledge and experience can further damage the data and reduce the chances of successful recovery. Therefore, it is recommended to seek the assistance of professional data recovery services who have the expertise and tools to handle such situations.
