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.

Are there any specific system logs or event notifications to monitor for early detection of data loss on NAS Raidon Mobile Rack iR8774 devices?

There are several system logs and event notifications that you can monitor for early detection of data loss on NAS Raidon Mobile Rack iR8774 devices. Here are a few key ones:

  1. RAID Controller Logs: The RAID controller in the NAS device maintains logs that can provide information about any disk failures, rebuilds, or other issues related to the RAID array. Monitoring these logs can help you identify any potential data loss events.
  2. Disk SMART Data: Most modern hard drives support Self-Monitoring, Analysis, and Reporting Technology (SMART). SMART data provides information about the health and status of the disks, including any signs of failure or degradation. Monitoring the SMART data can help you detect potential data loss events before they occur.
  3. NAS System Logs: The NAS device itself maintains system logs that can provide valuable information about any errors, warnings, or failures related to the file system, network connectivity, or other critical components. Monitoring these logs can help you identify any issues that might lead to data loss.
  4. Email Notifications: Many NAS devices allow you to configure email notifications for specific events, such as disk failures, RAID rebuilds, or file system errors. By enabling these notifications, you can receive real-time alerts about potential data loss events.
  5. Performance Monitoring: Monitoring the performance of the NAS device, such as disk I/O rates, CPU usage, or network throughput, can help you identify any abnormal behavior that might indicate a data loss event.

It is important to consult the documentation or user manual of your specific NAS Raidon Mobile Rack iR8774 device to understand the available logs and event notification options.

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

Although NAS Mobile Rack iR8774 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Raidon Mobile Rack iR8774. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a Raidon

Mobile Rack iR8774 has 2 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • APFS / HFS+;
  • Ext2 / Ext3 / Ext4;

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.

  4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The Raidon Mobile Rack iR8774 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.

    Can data recovery from a NAS Raidon Mobile Rack iR8774 device be done if the storage disks have been physically removed or replaced?
    • Hetman Software

      If the storage disks have been physically removed or replaced from a NAS Raidon Mobile Rack iR8774 device, data recovery can still be possible depending on the circumstances. Here are a few factors to consider:

      1. Replacement disks: If the disks were replaced with new ones, the chances of data recovery are higher. However, if the new disks were initialized or formatted, it may significantly reduce the chances of recovering the data.
      2. Disk removal: If the original disks were removed but not physically damaged, data recovery may still be possible. However, if the disks were damaged or overwritten, the chances of recovery decrease.
      3. RAID configuration: The RAID configuration used in the NAS device can also affect data recovery. If it was a RAID 0 (striping) configuration, where data is split across multiple disks, the chances of recovery decrease as any missing disk would result in data loss. In RAID 1 (mirroring) or RAID 5 (striping with parity), there may be better chances of recovery as the data is spread across multiple disks with redundancy.
      4. Professional assistance: In cases where data recovery is critical, it is recommended to seek professional assistance from a data recovery service. They have specialized tools and expertise to handle complex data recovery scenarios.

      It's important to note that data recovery success cannot be guaranteed in all cases, and it's always advisable to have regular backups to avoid potential data loss situations.

Questions and answers

  • How does the NAS Raidon Mobile Rack iR8774 provide internet access to connected devices?

    The NAS Raidon Mobile Rack iR8774 does not provide internet access to connected devices directly. It is a storage device that allows you to connect multiple hard drives and create a Network Attached Storage (NAS) system.

    A NAS system is typically connected to a local area network (LAN) using an Ethernet cable. Once connected to the LAN, devices on the same network can access the storage provided by the NAS. The NAS can be accessed through a web interface or dedicated software, allowing users to upload, download, and manage files stored on the hard drives within the NAS.

    To provide internet access to connected devices, you would need a separate router or modem that connects to your internet service provider (ISP). The router or modem would then be connected to the NAS and other devices on the network, allowing them to access the internet through the ISP connection.
