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 QNAP 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 recommended steps to take after detecting or suspecting data loss on a NAS QNAP VS-8024U-RP device?

If you suspect or detect data loss on a QNAP VS-8024U-RP NAS device, here are some recommended steps to take:

1. Stop all write operations: As soon as you suspect data loss, stop any further write operations to the NAS device. This helps prevent overwriting of any potentially recoverable data.
2. Check hardware and connections: Ensure that all hardware components are properly connected and functioning correctly. Check cables, power supply, and network connections to eliminate any potential hardware issues.
3. Verify data loss: Confirm that data loss has indeed occurred by checking for missing or inaccessible files and folders. This can be done by accessing the NAS device's file system or through the QNAP management interface.
4. Contact QNAP support: Reach out to QNAP support for assistance. They can provide guidance specific to your device and help troubleshoot the issue. Provide them with detailed information about the problem and any error messages you encounter.
5. Perform data recovery: If QNAP support confirms data loss and cannot assist in restoring it, you may need to consider data recovery options. QNAP provides a data recovery service, or you can seek assistance from professional data recovery specialists who specialize in NAS devices.
6. Restore from backups: If you have regular backups of your data, restore the lost files from your backup solution. This step highlights the importance of maintaining up-to-date backups to minimize the impact of data loss.
7. Implement preventive measures: Once the data loss issue is resolved, take steps to prevent future incidents. This includes regular backups, implementing RAID for data redundancy, ensuring firmware and software updates are applied, and monitoring the health of your NAS device.

Remember, data recovery can be a complex and time-consuming process, so it's crucial to act promptly and seek professional help if necessary.

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

Although the NAS VS-8024U-RP 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 Order Remote Data Recovery

Step-by-Step Data Recovery with Hetman RAID Recovery

This program restores data from damaged RAID arrays and is fully compatible with QNAP VS-8024U-RP. 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 QNAP

VS-8024U-RP has 8 HDD slots, and it supports the following array types:

• RAID 50;
• RAID 60;
• RAID 6;
• RAID 5;
• RAID 10;
• RAID 0;
• RAID 1;
• JBOD;

NAS supports:

• ZFS;
• EXT4;
• EXT3;
• exFAT;
• FAT32 (External Disk Only);
• NTFS (External Disk Only);
• HFS+ (External Disk Read Only);

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.

   

4. 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 QNAP VS-8024U-RP network-attached storage keeps QTS (QuTS hero) 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.
