Promise UltraTrak RM8000 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from UltraTrak RM8000.

How to recover data from NAS Promise UltraTrak RM8000

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 Promise 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 utilizing redundant network connections or link aggregation protocols mitigate data loss risks for NAS Promise UltraTrak RM8000 devices?

Yes, utilizing redundant network connections or link aggregation protocols can help mitigate data loss risks for NAS Promise UltraTrak RM8000 devices.

Redundant network connections involve setting up multiple network interfaces on the NAS device and connecting them to separate switches or routers. This ensures that if one network connection fails, the device can still communicate through the other connections, reducing the risk of data loss due to network failures.

Link aggregation protocols, such as Link Aggregation Control Protocol (LACP) or Static Link Aggregation, allow multiple network connections to be combined into a single logical link. This increases the available bandwidth and provides redundancy. If one link fails, the traffic is automatically redirected to the remaining active links, minimizing data loss.

By implementing redundant network connections or link aggregation protocols, the NAS Promise UltraTrak RM8000 devices can improve network reliability, increase data availability, and reduce the impact of network failures on data loss risks.

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

Although NAS UltraTrak RM8000 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.

Questions and answers

  • What is SSH and how does it work in the context of remote access and secure communication?

    SSH stands for Secure Shell, and it is a cryptographic network protocol used for secure remote access and secure communication over an unsecured network. It provides a secure channel between a client and a server, allowing users to access and manage remote systems securely.

    SSH works by establishing an encrypted connection between the client and the server. When a client initiates an SSH connection to a server, it goes through a process called SSH handshake, which involves the following steps:

    1. Client-server negotiation: The client and server negotiate the encryption algorithms, authentication methods, and other parameters to be used for the session.
    2. Key exchange: The client and server exchange cryptographic keys to establish a secure connection. This key exchange is typically done using Diffie-Hellman key exchange algorithm.
    3. User authentication: The client provides its credentials (username and password or public key) to the server for authentication. The server verifies the provided credentials and grants access if they are valid.
    4. Secure channel creation: Once the client is authenticated, a secure channel is created between the client and the server. This channel encrypts all the data transmitted between them, ensuring confidentiality and integrity.
    5. Remote access and secure communication: With the secure channel established, the client can now remotely access the server's command-line interface or execute specific commands. The client's commands and server's responses are encrypted and transmitted securely over the network.

    SSH utilizes various encryption algorithms, such as symmetric encryption for data encryption, asymmetric encryption for key exchange, and hashing algorithms for integrity checks. It also supports various authentication methods, including passwords, public key authentication, and two-factor authentication, to ensure secure access to remote systems.

    Overall, SSH provides a secure and encrypted communication channel, protecting sensitive data and preventing unauthorized access or eavesdropping during remote access sessions.
