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 Infortrend 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 regular data integrity checks help prevent data loss in NAS Infortrend EonStor CS 4014U devices?

Regular data integrity checks can help identify and prevent data loss in NAS devices like the Infortrend EonStor CS 4014U. These checks involve verifying the integrity of data stored on the device by comparing it to a known checksum or hash value. If the calculated checksum does not match the expected value, it indicates that the data has been altered or corrupted.

By regularly performing data integrity checks, you can proactively identify any inconsistencies or data corruption issues before they lead to data loss. This allows you to take appropriate actions, such as restoring data from backups or repairing the affected files, to prevent further data loss.

Additionally, it is important to ensure that the NAS device itself has built-in data protection mechanisms such as RAID (Redundant Array of Independent Disks), which can provide fault tolerance and redundancy to protect against hardware failures and minimize the risk of data loss.

However, it is worth noting that while regular data integrity checks can help prevent data loss, they are not a foolproof solution. It is crucial to have a comprehensive data backup strategy in place, including off-site backups, to ensure data recoverability in case of catastrophic events or unforeseen circumstances.

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

Although the NAS EonStor CS 4014U 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 Infortrend EonStor CS 4014U 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.
