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.

Are there any known issues or limitations when using NAS TerraMaster U24-612 devices with virtualization platforms such as VMware or Hyper-V?

There are a few known limitations and issues when using TerraMaster U24-612 devices with virtualization platforms like VMware or Hyper-V:

  1. Limited CPU and Memory: The U24-612 devices usually come with lower-end processors and limited memory capacity, which may restrict the number of virtual machines (VMs) that can be hosted and the performance of those VMs.
  2. Lack of Hardware Virtualization Support: Some TerraMaster U24-612 models do not support hardware virtualization technologies like Intel VT-x or AMD-V. This limitation can prevent certain advanced virtualization features from being utilized.
  3. Compatibility with Hypervisor: Although TerraMaster U24-612 devices can be used as storage for virtualization platforms, it's important to ensure compatibility with the specific hypervisor being used. Not all TerraMaster models may be officially supported or certified by VMware or Microsoft for their respective virtualization platforms.
  4. Network Performance: The U24-612 devices typically come with Gigabit Ethernet ports, which may limit network performance in scenarios where high network throughput is required for VMs.
  5. Lack of Redundancy: Some TerraMaster U24-612 models may lack redundant power supplies or RAID configurations, which can be important for ensuring high availability and data protection in virtualized environments.

It is recommended to carefully review the specifications and compatibility of the specific TerraMaster U24-612 model with the virtualization platform being used before deploying it in a production environment.

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

Although NAS U24-612 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 U24-612 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, there are several error codes or messages that may indicate the need for data recovery from a NAS TerraMaster U24-612 device. Some of the common ones include:

      1. "Disk Failure" or "Drive Offline" message: This indicates that one or more hard drives in the NAS have failed or are not functioning properly. It can lead to data loss and may require data recovery.
      2. "RAID Degraded" or "RAID Rebuilding" message: This suggests that the RAID array is in a degraded state due to a failed or disconnected drive. In such cases, data recovery may be necessary to retrieve the data from the failed drive or rebuild the RAID array.
      3. "Volume Corruption" or "File System Error" message: This indicates that the file system on the NAS has become corrupted, which can result in data inaccessibility or loss. Data recovery tools or services may be required to recover the data from the corrupted volume.
      4. "Invalid Password" or "Access Denied" message: If you are unable to access your data due to password issues or access restrictions, data recovery may be necessary to regain access to your files.
      5. "Data Loss" or "Data Inaccessibility" message: If you are unable to access your data or if files are missing or deleted unexpectedly, it may indicate data loss. In such cases, data recovery services can help in retrieving the lost data.

      It is important to note that if you encounter any of these error codes or messages, it is advisable to stop using the NAS immediately to prevent further damage or data loss. Instead, seek professional assistance from data recovery experts who specialize in NAS devices like the TerraMaster U24-612.
