How to recover data from Raidon Mobile Rack iR2774 NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS Raidon Mobile Rack iR2774

Raidon Mobile Rack iR2774 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from Mobile Rack iR2774.

How to recover data from NAS Raidon Mobile Rack iR2774

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 Raidon also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

How can a NAS Raidon Mobile Rack iR2774 device's power management settings impact data availability and potential loss?

The power management settings of a NAS Raidon Mobile Rack iR2774 device can have a significant impact on data availability and potential loss. Here are a few ways in which these settings can affect data:

  1. Power Failure: If the power management settings are not properly configured, the device may shut down unexpectedly during a power outage. This can lead to data loss or corruption if any ongoing read or write operations are interrupted.
  2. Disk Spinning: Power management settings can control how quickly the hard disks spin down when not in use. If the disks spin down too quickly, it can cause delays when accessing data, especially if the disks need to spin up again. This can impact data availability and slow down overall system performance.
  3. RAID Rebuilds: In a RAID configuration, if a disk fails and needs to be replaced, the power management settings can affect how quickly the RAID array rebuilds the data onto the new disk. If the settings are too aggressive and cause the disks to spin down frequently, it may prolong the rebuild process, increasing the risk of data loss if another disk fails during this time.
  4. Data Integrity: Power management settings can also impact the overall health and integrity of the data stored on the disks. For example, if the settings cause the disks to spin down too frequently, it can increase the wear and tear on the disks, potentially leading to disk failures and data loss.

To mitigate these risks, it is important to configure power management settings appropriately for the specific needs of the NAS device and the data it stores. It is recommended to strike a balance between power savings and data availability, ensuring that the device remains operational during power outages and that the disks are not excessively spun down, especially in critical RAID configurations.

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

Although NAS Mobile Rack iR2774 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 Raidon Mobile Rack iR2774 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.

      The NAS Raidon Mobile Rack iR2774 device does not specify any specific encryption methods in its product documentation. However, it is important to note that encryption can affect data recovery in general. If the device uses encryption to secure the data, it may require decryption to access the data, and without the proper encryption key or passphrase, data recovery may be difficult or impossible. It is always recommended to backup important data and keep encryption keys or passphrases securely stored to ensure data recovery in case of any issues.

  • Can you explain the specific virtualization capabilities of the NAS Raidon Mobile Rack iR2774 and how they can be utilized in a virtualized environment?

    The NAS Raidon Mobile Rack iR2774 is a hardware device designed for network-attached storage (NAS) solutions. It does not have specific virtualization capabilities built-in. However, it can be utilized in a virtualized environment through the following methods:

    1. NAS Virtualization: The iR2774 can be used as a storage device for virtual machines (VMs) running on a virtualization platform such as VMware or Hyper-V. The NAS can provide shared storage to multiple VMs, allowing them to access and store data on the iR2774.
    2. iSCSI Support: The iR2774 may support iSCSI (Internet Small Computer System Interface), which enables the NAS to present its storage as a block-level device to virtualization hosts. This allows the NAS to act as a storage target for virtual machines, appearing as if it were a locally attached disk.
    3. Backup and Disaster Recovery: In a virtualized environment, the iR2774 can be used as a backup target for virtual machine backups. Virtualization platforms often have built-in backup tools or support third-party backup software that can directly store backups on the NAS.
    4. High Availability: The iR2774 can be utilized in a high availability (HA) setup for virtualized environments. By configuring the NAS in a redundant manner (e.g., using RAID configurations), it can provide fault tolerance and data redundancy for virtual machines, ensuring continuous availability and protection against hardware failures.
    5. Storage for Virtual Desktop Infrastructure (VDI): In a virtual desktop infrastructure deployment, the iR2774 can act as the storage repository for virtual desktops. The NAS can store the virtual desktop images, user profiles, and other data required for VDI, allowing centralized management and easy provisioning of virtual desktops.

    It's important to note that while the iR2774 can be used in a virtualized environment, it does not provide virtualization features itself. It primarily serves as a storage solution that can be integrated into a virtualization infrastructure to enhance storage capabilities and support virtual machine deployments.
