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.

Are there any specific system logs or event notifications to monitor for early detection of data loss on NAS Synology FlashStation FS3400 devices?

Yes, there are specific system logs and event notifications that you can monitor for early detection of data loss on NAS Synology FlashStation FS3400 devices. Here are a few examples:

SMART (Self-Monitoring, Analysis, and Reporting Technology) Logs: Synology NAS devices support SMART technology, which monitors the health of hard drives. You can check the SMART logs regularly for any indications of failing drives or potential data loss issues.
RAID Rebuild Notifications: If you have configured your Synology FS3400 with RAID (Redundant Array of Independent Disks), you should monitor the RAID rebuild notifications. A rebuild process is triggered when a drive fails, and monitoring this process can help you identify potential data loss situations.
System Event Logs: Synology NAS devices maintain system event logs that record various activities and errors. Monitoring these logs can help you detect any unusual or critical events that may indicate data loss or other problems.
Disk Health Notifications: Synology DSM (DiskStation Manager) provides disk health notifications that alert you to any potential issues with the hard drives, such as bad sectors or high error rates. Keeping an eye on these notifications can help you identify data loss risks.
Data Scrubbing Reports: Synology NAS devices offer data scrubbing functionality, which verifies and repairs data integrity on a regular basis. Monitoring the data scrubbing reports can help you identify any inconsistencies or potential data loss scenarios.

It is important to regularly review and monitor these logs and notifications to ensure early detection of data loss or any other issues on your Synology FlashStation FS3400 NAS device.

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

Although the NAS FlashStation FS3400 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 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 Synology FlashStation FS3400. 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 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 FlashStation FS3400 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.
