Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Idis often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Are there any common mistakes or oversights made by users that can lead to data loss on NAS Idis DR-2308P devices?

While I couldn't find specific information on common mistakes or oversights specific to the NAS Idis DR-2308P devices, there are some general practices that users should be aware of to prevent data loss on any NAS device. Here are a few common mistakes or oversights that can lead to data loss:

  1. Lack of backup: One of the most common mistakes is not having a proper backup strategy in place. Users should regularly back up their important data to an external storage device or a cloud storage service to protect against data loss.
  2. Failure to update firmware: Neglecting to update the firmware of your NAS device can leave it vulnerable to security exploits or bugs that may lead to data loss. It is crucial to regularly check for firmware updates and apply them.
  3. Insufficient RAID configuration: RAID (Redundant Array of Independent Disks) offers data redundancy and protection against drive failures. However, users often overlook configuring RAID properly or using the appropriate RAID level for their needs. It is essential to understand the different RAID levels and choose the one that suits your requirements.
  4. Inadequate security measures: Weak or default passwords, lack of access controls, or not enabling encryption can make your NAS device vulnerable to unauthorized access or data breaches. Implementing strong passwords, enabling encryption, and setting up proper access controls are crucial to safeguard your data.
  5. Power-related issues: Abrupt power loss or power surges can lead to data corruption or loss. It is advisable to use a reliable uninterruptible power supply (UPS) to protect your NAS device from sudden power interruptions.
  6. Neglecting hard drive health: Hard drives can fail over time, leading to potential data loss. Regularly monitoring the health of your hard drives, including checking for SMART (Self-Monitoring, Analysis, and Reporting Technology) errors, can help identify potential issues before they result in data loss.

To ensure data safety, it is always recommended to refer to the user manual or documentation specific to your NAS device, as it may provide device-specific guidelines and precautions to prevent data loss.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS DR-2308P can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

  1. Power off the NAS and disconnect it from the power source.

    WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.

  2. Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.

  3. Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.

  4. Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

How to Safely Recover Data from Disk Images

This utility allows you to create a complete copy of a disk and work with the disk image instead of the physical drive. This approach helps protect your data from:

  • Overwriting during the recovery process;
  • Additional data loss caused by bad sectors;
  • User errors.

To create a disk image, follow these steps:

  1. Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.

  2. In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.

  3. When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.

Where Are the User’s Files Actually Stored?

The Idis DR-2308P 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.
