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 are the risks of data loss due to firmware or software malfunctions in NAS Thecus N16910SAS devices?

There are several risks of data loss due to firmware or software malfunctions in NAS Thecus N16910SAS devices:

  1. Data corruption: Firmware or software malfunctions can lead to data corruption, where the stored data becomes unreadable or unusable. This can result in the loss of important files and documents.
  2. System instability: Malfunctions in the firmware or software can cause the NAS device to become unstable and crash frequently. This can disrupt data access and increase the risk of data loss.
  3. Incomplete backups: NAS devices often rely on backup solutions to protect data. If the firmware or software malfunctions, it may affect the backup process, resulting in incomplete or failed backups. This can make it difficult to recover lost data in case of a failure.
  4. Security vulnerabilities: Malfunctioning firmware or software can introduce security vulnerabilities, making the NAS device susceptible to cyberattacks. Hackers can exploit these vulnerabilities to gain unauthorized access, delete or encrypt data, or inject malicious code, leading to data loss or theft.
  5. Limited recovery options: In some cases, firmware or software malfunctions can render the NAS device inoperable, making it challenging to recover data. If the device cannot be repaired or the data cannot be accessed, the risk of permanent data loss increases.

To mitigate these risks, it is essential to regularly update the firmware and software of the NAS device, maintain proper backups on separate storage devices, and follow best practices for data security and protection.

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

Although NAS N16910SAS 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 Thecus N16910SAS 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.
