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 specific precautions to take while migrating data between NAS Infortrend EonStor DS 3060 devices?
Yes, there are several precautions to consider while migrating data between NAS Infortrend EonStor DS 3060 devices:
- Backup your data: Before starting the migration process, it is crucial to create a backup of all your important data. This ensures that you have a copy of your files in case of any unforeseen issues during the migration.
- Plan the migration process: Develop a detailed plan for the migration process, including the timeline, steps, and resources required. This will help you stay organized and minimize any potential disruptions.
- Verify compatibility: Ensure that the target NAS Infortrend EonStor DS 3060 device is compatible with the source device. Check for any specific requirements or limitations mentioned in the product documentation or contact Infortrend support for assistance.
- Check available storage space: Make sure that the target NAS device has enough storage space to accommodate the data being migrated. If necessary, consider expanding the storage capacity before initiating the migration.
- Network connectivity: Ensure that both the source and target NAS devices have a stable network connection. This will help in maintaining data integrity and reducing the chances of data loss or corruption during the migration process.
- Test the migration process: Before performing the actual migration, it is recommended to perform a test migration with a small subset of data. This will help identify any potential issues or challenges that need to be addressed before migrating the entire dataset.
- Monitor the migration process: During the migration, closely monitor the progress and performance of the data transfer. Keep an eye on any error messages or warnings that may indicate issues with the migration process.
- Verify data integrity: Once the migration is complete, verify the integrity of the migrated data by performing thorough checks and tests. Compare the migrated data with the original data to ensure that no data loss or corruption has occurred.
- Update configurations and settings: After the migration, update any necessary configurations and settings on the target NAS device to ensure optimal performance and compatibility with your environment.
- Seek professional assistance if needed: If you are unsure or inexperienced in migrating data between NAS devices, consider seeking professional assistance from Infortrend support or a qualified IT professional to ensure a smooth and successful migration process.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS EonStor DS 3060 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.

Step-by-Step Data Recovery with Hetman RAID Recovery
This program restores data from damaged RAID arrays and is fully compatible with Infortrend EonStor DS 3060. Each hard disk in the array contains technical metadata describing how files were written. When launched, Hetman RAID Recovery analyzes this metadata, automatically reconstructs the damaged array, and provides access to its contents. After that, you can browse the recovered disk and save your files. The program can also restore files that were accidentally deleted from the network drive.
How to recover data from a Infortrend
EonStor DS 3060 has 60 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- RAID 6;
- RAID 50;
- RAID 60;
- JBOD;
NAS supports:
- exFAT, VFAT, FAT 12 / 16 / 32;
- NTFS / ReFS;
- APFS / HFS+;
- Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
- VMFS / HikvisionFS;
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 Infortrend EonStor DS 3060 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.

Yes, it is possible to recover data from a NAS Infortrend EonStor DS 3060 device that has been affected by a controller card failure or interface problem. However, the process may vary depending on the specific circumstances and the severity of the issue.
If the controller card has failed, it may be necessary to replace the card with a working one in order to regain access to the data. In some cases, the data may be recoverable by simply replacing the card and ensuring that the NAS device is properly configured.
If there is an interface problem, such as a faulty connection or cable, it may be possible to resolve the issue by fixing or replacing the problematic components. This can help restore the connection and allow access to the data.
In more severe cases, where the controller card or interface problem cannot be easily resolved, it may be necessary to seek the assistance of a professional data recovery service. These services specialize in recovering data from various storage devices, including NAS devices. They have the expertise and tools required to diagnose and repair complex issues, and can often recover data even in challenging situations.
It is important to note that in any data recovery scenario, it is crucial to avoid further attempts to access the data or perform DIY repairs, as these can potentially cause more harm and make the recovery process more difficult. It is recommended to seek professional help to maximize the chances of successful data recovery.
