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

It is important to note that data recovery success may vary depending on the extent of data loss and the condition of the NAS device. It is recommended to consult with a professional data recovery service provider or try different software options to increase the chances of successful data recovery.

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

Although NAS Turbo Station TS-221 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.

How to recover data from a QNAP

Turbo Station TS-221 has 2 HDD slots, and it supports the following array types:

  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • EXT4;
  • EXT3;
  • FAT32 (External Disk Only);
  • NTFS (External Disk Only);
  • HFS+ (External Disk Read Only);

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 QNAP Turbo Station TS-221 network-attached storage keeps QTS 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.

    Note: It is important to ensure that your media files are in a compatible format for iTunes and that they are stored in a location accessible by the QNAP Turbo Station TS-221 NAS.

  • Can the QNAP Turbo Station TS-221 NAS support iTunes Home Sharing for seamless media access across multiple devices?

    Yes, the QNAP Turbo Station TS-221 NAS supports iTunes Home Sharing. It allows you to share your media library across multiple devices, including Apple devices, for seamless access and streaming.

  • Are there any limitations or compatibility issues when using iTunes on a QNAP Turbo Station TS-221 NAS, and how can they be resolved?

    There may be some limitations and compatibility issues when using iTunes on a QNAP Turbo Station TS-221 NAS. Here are a few potential issues and possible resolutions:

    1. NAS Performance: The TS-221 NAS may not have the same performance capabilities as a dedicated computer running iTunes. This could lead to slower response times, especially when dealing with a large library or streaming media. To resolve this, ensure that your NAS has sufficient resources (CPU, RAM, etc.) and consider upgrading if necessary.
    2. iTunes Version: QNAP NAS devices often run a modified version of iTunes, which may not always be the latest version available. This could result in compatibility issues with certain features or devices. Check for firmware updates from QNAP to ensure you have the latest iTunes version compatible with your NAS.
    3. AirPlay Compatibility: AirPlay streaming from iTunes on the NAS to external devices may not work seamlessly due to network configurations or limitations. Ensure that your NAS and the device you're streaming to are on the same network and that AirPlay is enabled and properly configured on both.
    4. Music Library Access: While iTunes on a NAS can store and manage your music library, accessing it from other devices (such as iPhones or iPads) may require additional steps. You may need to configure Home Sharing or use third-party apps to access and stream your iTunes library from external devices.
    5. Third-Party Apps: QNAP NAS devices have a range of third-party apps available, including media servers and music players. These apps can provide alternative ways to access and stream your iTunes library, potentially offering better compatibility and performance. Explore the QNAP App Center for apps that suit your needs.

    It's important to note that compatibility and limitations can vary depending on the specific model of the QNAP Turbo Station NAS and the version of iTunes installed. Review the QNAP documentation, user forums, and support resources for your specific NAS model to find more detailed information and solutions.
