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 improper configuration of network settings or IP addresses result in data loss on NAS Thecus N16000PRO devices?

Yes, improper configuration of network settings or IP addresses can potentially result in data loss on NAS Thecus N16000PRO devices. If the network settings are not properly configured, it can lead to connectivity issues, making it difficult to access or transfer data to and from the NAS device. Additionally, incorrect IP address configuration can cause conflicts or prevent proper communication between the NAS device and other network devices, potentially leading to data loss or corruption. It is important to ensure that network settings and IP addresses are correctly configured to maintain proper functionality and prevent any potential data loss.

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

Although NAS N16000PRO 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.

    The Thecus N16000PRO NAS (Network Attached Storage) device provides several security measures to ensure safe file access from a remote location. Here are some of the key security features:

    1. Secure Remote Access: The NAS supports secure remote access protocols such as SSL/TLS (Secure Sockets Layer/Transport Layer Security) encryption. This ensures that the data transmitted between the remote location and the NAS is encrypted, preventing unauthorized access or interception.
    2. VPN Support: The NAS has built-in support for Virtual Private Network (VPN) connections. VPNs create a secure and encrypted tunnel between the remote location and the NAS, allowing users to access files securely as if they were on the same local network.
    3. Access Control: Thecus NAS devices offer robust access control mechanisms. Administrators can create user accounts with specific permissions and access rights, ensuring that only authorized users can access files remotely. Access control lists (ACLs) can be set up to define user-level or group-level permissions.
    4. Two-Factor Authentication (2FA): The NAS supports two-factor authentication, adding an extra layer of security. Users can enable 2FA, which requires them to provide a second form of authentication (such as a mobile app-generated code) in addition to their password when accessing files remotely.
    5. Firewall and IP Blocking: The NAS has a built-in firewall to protect against unauthorized access attempts. It can also block specific IP addresses or ranges to prevent potential threats or brute-force attacks.
    6. Data Encryption: Thecus NAS devices support data encryption at rest. Users can enable encryption for specific folders or the entire NAS, ensuring that data stored on the device is encrypted and protected from unauthorized access.
    7. Auditing and Logging: The NAS maintains detailed logs and auditing capabilities, allowing administrators to monitor and track file access activities. This helps in identifying any suspicious or unauthorized access attempts.

    It is important to note that while the Thecus N16000PRO provides robust security measures, it is also crucial for users to follow best practices such as using strong passwords, regularly updating firmware, and keeping backups of important files to ensure overall data security.

  • Are there any specific limitations or requirements for accessing files on the NAS Thecus N16000PRO from a remote location, such as network configurations or software compatibility?

    To access files on the Thecus N16000PRO NAS from a remote location, there are a few limitations and requirements to consider:

    1. Network Configuration: You need to have a stable internet connection with sufficient upload and download speeds. The NAS should be connected to a router or modem that is properly configured to allow remote access.
    2. Port Forwarding: You may need to set up port forwarding on your router to allow external access to the NAS. By default, the NAS uses port 8080 for HTTP and port 443 for HTTPS. Ensure that these ports are open and forwarded to the NAS's internal IP address.
    3. Dynamic DNS: If your internet connection has a dynamic IP address (which changes periodically), you will need to set up a dynamic DNS service. This service associates a domain name with your changing IP address, allowing you to access the NAS using a static domain name instead of the changing IP.
    4. VPN: It is recommended to set up a Virtual Private Network (VPN) for secure remote access. A VPN creates an encrypted connection between your remote device and the NAS, ensuring that your data remains secure during transmission.
    5. Software Compatibility: The Thecus N16000PRO supports various file sharing protocols such as SMB, AFP, FTP, and NFS. Ensure that the remote device you are using supports these protocols or has appropriate software to access the files on the NAS.
