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 the use of specific data compression or deduplication techniques impact the performance and data integrity on NAS Idis DR-1304P devices?

Yes, the use of specific data compression or deduplication techniques can impact the performance and data integrity on NAS Idis DR-1304P devices.

Data compression techniques aim to reduce the size of data, which can lead to improved storage efficiency and reduced bandwidth requirements. However, compression algorithms require computational resources to compress and decompress data, so enabling compression on a NAS device like the DR-1304P may result in increased CPU usage and potentially slower performance during data access or transfer.

Deduplication techniques eliminate redundant data by storing only unique data blocks and referencing them when needed. This can lead to significant storage savings, especially when dealing with large amounts of similar or duplicate data. However, deduplication also requires additional processing power and memory to identify and manage the unique data blocks. Enabling deduplication on the DR-1304P may result in increased CPU and memory usage, potentially impacting performance.

When considering the impact on data integrity, it is important to note that data compression and deduplication are both lossless techniques, meaning they do not result in any loss of data. However, any software or hardware-related issues during the compression or deduplication process could potentially introduce data corruption or integrity issues. Therefore, it is crucial to ensure that the compression or deduplication techniques used on the DR-1304P are reliable and thoroughly tested to minimize the risk of data integrity problems.

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

Although the NAS DR-1304P 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-1304P 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.
