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 Idis 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 compatibility issues or limitations when connecting NAS Idis DR-1304PC devices to different operating systems or platforms?

The IDIS DR-1304PC NAS devices are designed to be compatible with various operating systems and platforms. However, there may be some limitations or compatibility issues depending on the specific setup and requirements. Here are a few points to consider:

  1. Network Protocol: The IDIS DR-1304PC NAS devices typically support standard network protocols like SMB/CIFS (Windows), NFS (Unix/Linux), and AFP (Apple). Ensure that the operating systems or platforms you are connecting from support these protocols.
  2. File System: The NAS devices may use specific file systems like NTFS, FAT32, or exFAT. Some operating systems may have limitations in accessing certain file systems. For example, Windows may not support the native file system of a NAS device formatted for macOS.
  3. Device Drivers: In some cases, you may need to install specific device drivers or software provided by the NAS manufacturer to ensure proper connectivity and functionality. Check if the necessary drivers are available for the target operating system or platform.
  4. Permissions and Authentication: Ensure that the NAS device and the connected operating systems or platforms have compatible authentication mechanisms and user permissions. This is important for accessing and managing files stored on the NAS.
  5. Software Integration: If you plan to use specific software or applications to access the NAS devices, verify their compatibility with the target operating systems or platforms. Some software may have limitations or require additional configuration to work with NAS devices.

To ensure seamless compatibility and minimize potential issues, it is advisable to consult the documentation and support resources provided by IDIS or contact their technical support for specific compatibility information related to the DR-1304PC NAS devices.

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

Although NAS DR-1304PC 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 Idis DR-1304PC 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.

    How does data recovery from NAS Idis DR-1304PC differ from other storage devices?
    • Hetman Software
      Hetman Software 27.08.2023 04:59 #

      Data recovery from NAS Idis DR-1304PC differs from other storage devices in a few ways:

      1. Network-Attached Storage (NAS): The Idis DR-1304PC is a NAS device, which means it is designed to provide centralized storage and file sharing over a network. Unlike other storage devices like hard drives or solid-state drives, NAS devices are connected to a network and accessed by multiple users simultaneously. This networking aspect adds complexity to the data recovery process.
      2. RAID Configuration: The Idis DR-1304PC typically uses a RAID (Redundant Array of Independent Disks) configuration for data storage. RAID combines multiple physical drives into one logical unit, providing better performance, fault tolerance, and data redundancy. Data recovery from a NAS with RAID involves understanding the specific RAID level used (e.g., RAID 0, RAID 1, RAID 5) and employing specialized techniques to rebuild the array and recover the data.
      3. File System: NAS devices often use different file systems than traditional storage devices. The Idis DR-1304PC may use file systems like ext4 or XFS, which are commonly found in Linux-based NAS systems. Data recovery specialists need to be familiar with these file systems and have the necessary tools and expertise to recover data from them.
      4. Remote Access: NAS devices allow remote access, which means data recovery may need to be performed remotely. This requires establishing a secure connection to the device over the network and employing specialized techniques to retrieve the data without physical access to the device.

      Overall, data recovery from NAS Idis DR-1304PC involves understanding the unique aspects of NAS devices, such as network connectivity, RAID configurations, specific file systems, and remote access capabilities. Data recovery specialists skilled in NAS recovery techniques are required to effectively recover data from such devices.
