Thecus N199 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from N199.

How to recover data from NAS Thecus N199

Recover data from damaged RAID arrays inaccessible from a computer.

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 Thecus also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

What is a NAS Thecus N199 (Network Attached Storage) device?

The Thecus N199 is a Network Attached Storage (NAS) device produced by Thecus Technology Corp. It is a compact and high-performance storage solution designed for small businesses and home users.

The NAS Thecus N199 allows users to store and share data over a network, providing centralized storage for multiple devices. It typically consists of one or more hard drives (or SSDs) that are connected to a local area network (LAN) through an Ethernet port.

The device offers various features such as data backup and synchronization, file sharing, media streaming, and remote access. It often runs on a dedicated operating system specifically designed for NAS devices, allowing users to easily manage and configure the storage settings through a web-based interface.

The Thecus N199 is known for its reliability, performance, and scalability, making it suitable for both personal and professional use cases where data storage and accessibility are crucial.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS N199 can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:

  1. Turn off the storage and disconnect it from the power supply.

    WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.

  2. Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.

  3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

  4. Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Thecus N199. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

N199 has 1 HDD slots, and it supports the following array types:


NAS supports:

  • EXT3;
  • EXT4;
  • XFS;

Safe recovery from disk images

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

  • Overwriting during the recovery process;
  • Loss resulting from bad sectors;
  • User mistakes.

To create an image, do the following:

  1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

  2. Select the disk in the main window, and choose from the menu ToolsSave Disk. You can select multiple disks to be saved.

  3. When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.

Where are user’s files stored?

The Thecus N199 network-attached storage keeps OS Linux 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.

      Yes, data recovery from a NAS Thecus N199 device can still be performed even if there are issues with the network protocols or settings. In such cases, you may not be able to access the NAS device through the network, but you can still recover the data by directly connecting the NAS hard drives to a computer.

      Here are the general steps to recover data from a NAS Thecus N199 device:

      1. Shut down the NAS device and remove the hard drives.
      2. Connect the hard drives to a computer using a SATA to USB adapter or by installing them internally.
      3. Use data recovery software such as EaseUS Data Recovery Wizard, Recuva, or Disk Drill to scan the connected NAS hard drives and recover the desired data.
      4. Select the files you want to recover and save them to a different storage location, preferably an external hard drive or another computer.
      5. Once the data is recovered, you can troubleshoot and fix the network issues on the NAS device separately.

      Keep in mind that data recovery success depends on the condition of the hard drives and the extent of the issues with the NAS device. It is always recommended to consult with a professional data recovery service if you are unsure or if the data is critical.
