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 Promise 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.
How can RAID (Redundant Array of Independent Disks) configurations impact data loss in NAS Promise FileCruiser VA2600 devices?
RAID configurations in NAS Promise FileCruiser VA2600 devices can have a significant impact on data loss prevention. Here are a few ways RAID can help mitigate data loss:
- Fault tolerance: RAID configurations, such as RAID 1 (mirroring) or RAID 5 (striping with parity), provide redundancy by distributing data across multiple disks. In case of a single disk failure, the system can continue to operate without any data loss. The failed disk can be replaced, and the data can be rebuilt from the remaining disks.
- Increased reliability: By combining multiple disks into an array, RAID configurations improve overall system reliability. If one disk fails, the system can still function with the remaining disks. This reduces the chances of complete system failure and subsequent data loss.
- Faster data recovery: In the event of a disk failure, RAID configurations can expedite data recovery. With RAID 1, the data is mirrored across multiple disks, allowing for quick access to the redundant copy. RAID 5 uses parity information to rebuild the data on a replacement disk, minimizing the time required to restore the data.
- Hot-swappable drives: Many NAS devices, including the Promise FileCruiser VA2600, support hot-swappable drives. This means that failed drives can be replaced without shutting down the system or interrupting user access to data. Hot-swapping enables quicker recovery and reduces the risk of data loss during the replacement process.
- RAID monitoring and management: NAS devices often provide RAID monitoring and management tools. These tools can alert administrators in case of disk failures or other issues, allowing proactive measures to be taken to prevent data loss. Regular monitoring and maintenance of RAID configurations can help identify potential problems before they escalate into data loss situations.
It is important to note that while RAID configurations can greatly reduce the risk of data loss, they are not foolproof. Other factors such as power surges, natural disasters, human errors, or multiple disk failures can still lead to data loss. Therefore, it is crucial to have additional backup strategies in place, such as offsite backups or cloud storage, to further protect critical data.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS FileCruiser VA2600 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 Promise FileCruiser VA2600. 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 Promise
FileCruiser VA2600 has 16 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 1E;
- RAID 3;
- RAID 5;
- RAID 6;
- RAID 30;
- 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 Promise FileCruiser VA2600 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.

Data recovery from a NAS Promise FileCruiser VA2600 device can be challenging if there are issues with the disk array or storage pool. However, it may still be possible to recover the data depending on the specific problem and the severity of the issue.
If there are disk failures in the array, the first step would be to replace the faulty disks and rebuild the array. Once the array is rebuilt, the data may be accessible again. However, if there are multiple disk failures or if the array is not rebuildable, the data recovery process becomes more complex and may require professional assistance.
If there are issues with the storage pool, such as corruption or misconfiguration, it may be necessary to troubleshoot and repair the pool before attempting data recovery. This can involve using the device's management interface or command-line tools to diagnose and fix the problem.
In any case, it is recommended to consult with a professional data recovery service or contact the manufacturer's support for guidance on recovering data from a NAS Promise FileCruiser VA2600 device with disk array or storage pool issues.
