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.

Can hardware upgrades or modifications lead to data loss if not properly executed on NAS Synology Cube Station CS407 / CS407e devices?

Yes, hardware upgrades or modifications can potentially lead to data loss if not properly executed on NAS Synology Cube Station CS407 / CS407e devices. Any incorrect installation or incompatible hardware can cause damage to the existing data or the entire system. It is always recommended to follow the manufacturer's instructions and consult with professionals or Synology support to ensure a safe and successful hardware upgrade or modification process. Additionally, it is crucial to have a backup of important data before performing any hardware changes to mitigate the risk of data loss.

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

Although the NAS Cube Station CS407 / CS407e 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.
