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 Synology 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 data be recovered from a NAS Synology DiskStation DS409+ / DS409 / DS409slim device after a malfunction or data loss event?

There are several methods to recover data from a NAS Synology DiskStation DS409+ / DS409 / DS409slim device after a malfunction or data loss event. Here are some steps you can follow:

Check the hardware: Ensure that the NAS device is properly connected to power and network. Verify that the hard drives are functioning correctly and have not failed.
Use Synology Data Recovery: Synology provides a software tool called "Synology Data Recovery" that can be used to recover data from a malfunctioning NAS device. This software can be downloaded from the Synology website and installed on a computer.
Connect the hard drives to a computer: If the NAS device is not functioning, you can remove the hard drives from the NAS and connect them to a computer using a SATA to USB adapter or by installing them internally. Make sure to connect the drives one at a time to avoid confusion.
Use data recovery software: Once the hard drives are connected to a computer, you can use data recovery software such as EaseUS Data Recovery Wizard, Stellar Data Recovery, or Recuva to scan the drives and recover the lost data. These software tools have options to recover files, folders, or even entire partitions.
Seek professional data recovery services: If the above methods fail or if the data is critical and cannot be risked, it is recommended to seek professional data recovery services. There are several companies that specialize in NAS data recovery and have the expertise and tools to recover data from malfunctioning NAS devices.

Remember to always have a backup of your data to prevent data loss events.

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

Although the NAS DiskStation DS409+ / DS409 / DS409slim 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.

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 Synology DiskStation DS409+ / DS409 / DS409slim network-attached storage keeps DSM (DiskStation Manager) 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.
