How to recover data from Thecus N5200XXX NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Thecus N5200XXX

Thecus N5200XXX NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from N5200XXX.

How to recover data from NAS Thecus N5200XXX

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.

Can excessive drive spin-down or power-saving settings impact data retrieval in case of failure on NAS Thecus N5200XXX devices?

Excessive drive spin-down or power-saving settings can potentially impact data retrieval in case of failure on NAS Thecus N5200XXX devices.

When drives are set to spin down frequently or enter power-saving mode, it can increase the response time when accessing data. If a drive fails while in this state, it may take longer for the NAS device to recognize the failure and initiate the necessary steps for data recovery.

Additionally, frequent spin-downs and power-saving settings can put more stress on the drives as they have to constantly start and stop, potentially leading to premature wear and tear. This can increase the chances of drive failure and make data retrieval more difficult in case of a failure.

It is recommended to strike a balance between power-saving and data accessibility. Setting longer spin-down intervals or using intelligent power-saving features that consider drive usage patterns can help reduce power consumption without significantly impacting data retrieval in case of failure.

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

Although NAS N5200XXX 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.

N5200XXX has 5 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • RAID 10;
  • JBOD;

NAS supports:

  • EXT3;

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 N5200XXX 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.

      Data recovery from a NAS device like Thecus N5200XXX should not affect the existing data if it is done correctly. However, it is always recommended to take precautions and avoid any potential risks. Here are a few things to consider:

      1. Do not write any new data to the NAS device: To minimize the risk of overwriting the existing data, avoid using the NAS device until the data recovery process is complete.
      2. Use professional data recovery software or services: It is advisable to use specialized data recovery software or consult a professional data recovery service to ensure the best possible outcome. They have the expertise and tools to handle the recovery process safely.
      3. Follow proper procedures: When performing data recovery, follow the instructions provided by the software or service carefully. This may involve connecting the NAS device to a separate computer or using specific recovery modes.
      4. Create backups: Before attempting any data recovery, it is always recommended to have a backup of the existing data. This way, even if something goes wrong during the recovery process, you can restore the data from the backup.

      Remember, data recovery can be a complex process, and there is always a slight risk involved. It is best to consult professionals or seek expert advice to ensure the safety of your data.
