TerraMaster D2-340 TD2 Thunderbolt 3 Plus NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from D2-340 TD2 Thunderbolt 3 Plus.

How to recover data from NAS TerraMaster D2-340 TD2 Thunderbolt 3 Plus

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 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.

Can overheating or improper ventilation cause data loss on NAS TerraMaster D2-340 TD2 Thunderbolt 3 Plus devices?

Yes, overheating or improper ventilation can potentially cause data loss on NAS TerraMaster D2-340 TD2 Thunderbolt 3 Plus devices. Overheating can lead to damage to the internal components of the NAS, including the hard drives where the data is stored. Excessive heat can cause the hard drives to fail, resulting in data loss.

Proper ventilation is crucial for NAS devices to maintain optimal operating temperatures. If the device is not properly ventilated, it can lead to overheating and potential data loss. It is recommended to ensure that the NAS is placed in a well-ventilated area and that any cooling fans or vents are not obstructed.

To prevent data loss due to overheating or improper ventilation, it is important to regularly monitor the temperature of the NAS and take necessary steps to keep it within the recommended operating range. This may include providing adequate airflow, using cooling fans, or adjusting the placement of the device. Additionally, it is advisable to regularly back up the data stored on the NAS to an external storage device or cloud storage to mitigate the risk of permanent data loss.

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

Although NAS D2-340 TD2 Thunderbolt 3 Plus 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.

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 TerraMaster D2-340 TD2 Thunderbolt 3 Plus 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, it is possible to recover data from a NAS TerraMaster D2-340 TD2 Thunderbolt 3 Plus device even if it is not responding or freezing frequently. However, the process may vary depending on the specific issue causing the device to freeze or become unresponsive.

      Here are a few steps you can try to recover data from a non-responsive NAS device:

      1. Restart the device: Sometimes, a simple restart can fix minor software or connectivity issues. Power off the device, unplug it from the power source, wait for a few minutes, and then plug it back in and power it on.
      2. Check the network connection: Ensure that the NAS device is properly connected to the network and that the network settings are configured correctly. Try connecting the device directly to the computer via Ethernet cable to rule out any network-related issues.
      3. Update firmware: Check if there are any available firmware updates for the NAS device. Updating the firmware can often resolve compatibility or stability issues.
      4. Connect the drives to another system: If the NAS device continues to freeze or remain unresponsive, you can remove the hard drives from the NAS enclosure and connect them to another computer directly. This will allow you to access the data stored on the drives and perform data recovery.
      5. Seek professional help: If none of the above steps work, it is recommended to contact a professional data recovery service. They have specialized tools and expertise to recover data from malfunctioning or damaged NAS devices.

      Remember to always have a backup of your important data to avoid data loss situations.
