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 Digiever 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 preventive measures to minimize the risk of data loss on NAS Digiever DS-2116 UHD devices?

Yes, there are several preventive measures that can be taken to minimize the risk of data loss on NAS Digiever DS-2116 UHD devices. Here are some of them:

  1. Regular backups: Implement a backup strategy to regularly back up the data on the NAS device. This can be done using built-in backup features or third-party backup software.
  2. Redundancy: Use RAID (Redundant Array of Independent Disks) technology to create redundant copies of data across multiple hard drives. This helps protect against data loss in case of a drive failure.
  3. Uninterruptible Power Supply (UPS): Connect the NAS device to a UPS to protect it from power outages and voltage fluctuations. Sudden power loss can lead to data corruption or loss.
  4. Firmware updates: Keep the NAS device's firmware up to date. Manufacturers often release firmware updates to address security vulnerabilities and improve system stability.
  5. Network security: Implement strong passwords for user accounts and enable features like two-factor authentication. Regularly update and patch the NAS device's operating system and network security settings.
  6. Physical security: Place the NAS device in a secure location to prevent unauthorized physical access. This can help protect the device from theft or tampering.
  7. Monitoring and alerts: Enable system monitoring and alerts to receive notifications about any potential issues or failures. This allows for timely action to prevent data loss.
  8. Regular maintenance: Perform routine maintenance tasks such as checking hard drive health, cleaning dust from the device, and ensuring proper ventilation to prevent overheating.

It is important to note that while these preventive measures can help minimize the risk of data loss, they do not guarantee complete protection. It is always recommended to have a comprehensive data backup strategy in place.

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

Although NAS DS-2116 UHD 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.

DS-2116 UHD has 2 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • exFAT, VFAT, FAT 12 / 16 / 32;
  • NTFS / ReFS;
  • APFS / HFS+;
  • Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;

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 Tools – Save 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 Digiever DS-2116 UHD 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.

    7. User Permissions: Ensure that the user account accessing the NAS device has appropriate permissions to access the media files and use the iTunes Server app.
    8. Firewall and Security Settings: Check your network's firewall and security settings to allow iTunes and the NAS device to communicate. Ensure that necessary ports (such as TCP port 3689 for iTunes) are open and not blocked.
    9. Device Compatibility: Verify that the devices you intend to use to access iTunes (e.g., computers, iPhones, iPads, Apple TVs) are compatible with the version of iTunes and the media file formats supported by the Digiever DS-2116 UHD NAS device.

    By considering these requirements and compatibility factors, you can successfully set up iTunes support on your Digiever DS-2116 UHD NAS device.

  • Can the Digiever DS-2116 UHD NAS effectively handle large iTunes libraries, including high-definition media files, without any performance issues?

    The Digiever DS-2116 UHD NAS is designed to handle large iTunes libraries and high-definition media files. It supports up to 16 hard drives, providing ample storage capacity for large libraries. Additionally, it offers a powerful hardware configuration with a high-performance processor and ample RAM, which allows for smooth playback and streaming of high-definition media files. However, the actual performance may vary depending on factors such as the number of concurrent users, network bandwidth, and other applications running on the NAS. It is recommended to check the system requirements and specifications of the NAS to ensure it meets your specific needs.

  • Are there any limitations or restrictions when it comes to accessing iTunes content stored on a Digiever DS-2116 UHD NAS from different devices or platforms?

    Yes, there are limitations and restrictions when it comes to accessing iTunes content stored on a Digiever DS-2116 UHD NAS from different devices or platforms. The main limitation is that iTunes content is protected by digital rights management (DRM) which restricts playback to authorized devices and platforms.

    iTunes content purchased from the iTunes Store is usually encrypted with FairPlay DRM, which is designed to work only with Apple devices and platforms. This means that you can only access and play iTunes content from an authorized Apple device or a computer running iTunes software. Other devices or platforms, such as Android devices or non-Apple media players, may not be able to play the iTunes content directly.

    However, if you have non-DRM protected content (such as music in MP3 format) stored on the Digiever DS-2116 UHD NAS, you may be able to access and play it from different devices and platforms that support the respective file formats.
