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.

Are there any common mistakes or oversights made by users that can lead to data loss on NAS Infortrend EonStor GS 3012 devices?

While it is difficult to specify common mistakes or oversights made by users that can lead to data loss on NAS Infortrend EonStor GS 3012 devices specifically, there are some general practices that users should be aware of to prevent data loss on any NAS device. These include:

  1. Lack of Regular Backups: Not having a proper backup strategy is one of the most common mistakes that can lead to data loss. It is essential to regularly back up your data to an external storage device or cloud storage.
  2. Failure to Implement Redundancy: NAS devices often support various RAID configurations to provide redundancy and protect against data loss due to drive failures. Users should ensure that they have implemented the appropriate RAID level for their needs.
  3. Neglecting Firmware Updates: Firmware updates often include bug fixes, security patches, and performance improvements. Neglecting to update the firmware can leave your device vulnerable to potential issues that may result in data loss.
  4. Inadequate Security Measures: Weak passwords, improper access controls, and lack of encryption can make your NAS device susceptible to unauthorized access or data breaches. Implementing strong passwords, enabling encryption, and configuring proper access controls are crucial to safeguarding your data.
  5. Ignoring Environmental Factors: NAS devices should be kept in a suitable environment with proper ventilation and temperature control. Failure to do so can lead to overheating, which may cause hardware failures and data loss.
  6. Mishandling Drives: Improper handling of hard drives, such as dropping them or subjecting them to physical shocks, can lead to data loss. Users should handle drives with care and follow manufacturer guidelines for installation and maintenance.
  7. Power Outages and Surges: Sudden power outages or power surges can cause data corruption or hardware damage. Using an uninterruptible power supply (UPS) can help protect your NAS device from such events.

It is important to note that these are general best practices, and specific device models may have their own unique considerations. Users should refer to the manufacturer's documentation and guidelines for their specific NAS device to ensure proper usage and prevent data loss.

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

Although the NAS EonStor GS 3012 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.
