Why can’t ordinary software tools restore files from RAID?

Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.

Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.

Various RAID levels store information in different ways. Additionally, manufacturers like TerraMaster also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

  2. macOS: TerraMaster NAS devices are compatible with macOS, allowing users to access and manage files using Finder or other file management applications. However, some advanced features like Time Machine backups might require specific setup or configuration.
  3. Linux: TerraMaster NAS devices can be accessed from Linux systems, allowing file sharing and management. However, compatibility with specific Linux distributions and file systems might vary, and advanced features like NFS (Network File System) or Samba sharing might require additional configuration.
  4. Mobile platforms: TerraMaster provides dedicated mobile apps for iOS and Android devices, allowing users to access files, stream media, and manage the NAS remotely. However, the availability and functionality of certain features might differ between the mobile apps and the desktop client applications.
  5. Third-party software and protocols: TerraMaster NAS devices support various third-party software and protocols, such as Plex Media Server, Docker, FTP, and more. However, compatibility with specific versions or configurations of these software or protocols might vary.
