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 Seagate 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 regular data verification or checksum processes help maintain data integrity on NAS Seagate Nytro AP 2U24 devices?
Regular data verification or checksum processes can help maintain data integrity on NAS Seagate Nytro AP 2U24 devices in the following ways:
- Detecting and preventing data corruption: Data verification processes involve comparing the checksum or hash value of the data against a known value. By regularly verifying the integrity of the data stored on the NAS device, any corruption or alteration of the data can be identified. This helps in ensuring that the data remains intact and uncorrupted.
- Early detection of storage media errors: Regular data verification processes can help identify any errors or issues with the storage media, such as bad sectors or disk failures. By comparing the checksums of the data, any discrepancies can be detected, indicating potential issues with the storage medium. This allows for timely replacement or repair of the faulty components, minimizing the risk of data loss.
- Protection against data tampering or unauthorized modifications: Data verification processes can act as a security measure to ensure that the data stored on the NAS device has not been tampered with or modified without authorization. By comparing the checksums, any unauthorized changes to the data can be detected, helping to maintain data integrity and ensuring that the stored information remains trustworthy.
- Data recovery and restoration: In the event of data corruption or loss, regular data verification processes can facilitate data recovery and restoration. By comparing the checksums, it becomes easier to identify and isolate corrupted or missing data. This enables the restoration of the affected data from backups or redundant copies, ensuring minimal downtime and reducing the impact of data loss.
Overall, regular data verification or checksum processes provide an additional layer of protection to maintain data integrity on NAS Seagate Nytro AP 2U24 devices. They help in detecting and preventing data corruption, identifying storage media errors, protecting against unauthorized modifications, and facilitating data recovery in case of data loss.
How to Remove Hard Disks from Your NAS and Connect Them to a PC
Although the NAS Nytro AP 2U24 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 Seagate Nytro AP 2U24. 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 Seagate
Nytro AP 2U24 has 24 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 Seagate Nytro AP 2U24 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.
