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.

What is a NAS QNAP Turbo Station TS-259 Pro / TS-259 Pro+ (Network Attached Storage) device?

The QNAP Turbo Station TS-259 Pro / TS-259 Pro+ is a Network Attached Storage (NAS) device manufactured by QNAP Systems Inc. It is designed to provide centralized storage and file sharing capabilities for home and small office environments.

The TS-259 Pro / TS-259 Pro+ is equipped with a powerful Intel Atom dual-core processor, which allows for high-performance data transfer and multitasking.

The NAS device runs on QNAP's proprietary operating system, QTS, which offers a user-friendly web-based interface for easy management and configuration. It supports a wide range of features, including file sharing, remote access, data backup, multimedia streaming, and surveillance camera recording.

The TS-259 Pro+ is an upgraded version of the TS-259 Pro, offering a faster processor and more memory. It also includes additional features like USB 3.0 ports for faster data transfer and an HDMI output for direct multimedia playback on a TV or monitor.

Overall, the QNAP Turbo Station TS-259 Pro / TS-259 Pro+ is a versatile and reliable NAS device that provides secure and efficient storage solutions for personal and business use.

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

Although NAS Turbo Station TS-259 Pro / TS-259 Pro+ 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 QNAP Turbo Station TS-259 Pro / TS-259 Pro+ 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.

  • Can you explain the encryption capabilities of the NAS QNAP Turbo Station TS-259 Pro / TS-259 Pro+ and how it safeguards sensitive data during file access and transmission?

    The NAS QNAP Turbo Station TS-259 Pro / TS-259 Pro+ offers several encryption capabilities to safeguard sensitive data during file access and transmission. Here are the key encryption features:

    1. Shared Folder Encryption: The NAS supports AES 256-bit encryption for shared folders. You can enable encryption for specific folders, and all files stored within those folders will be encrypted. This ensures that even if someone gains unauthorized access to the NAS, they will not be able to access the encrypted files without the encryption key.
    2. Network Data Encryption: The NAS supports SSL/TLS protocols to encrypt data transmission over the network. This ensures that data sent between the NAS and other devices (such as computers or mobile devices) is encrypted, preventing unauthorized interception and access.
    3. Encrypted Remote Replication: The NAS allows you to encrypt data during remote replication. When replicating data to another QNAP NAS or remote server, you can enable encryption to ensure that the data remains protected during transmission and storage at the destination.
    4. Encrypted External Drives: The NAS supports encryption for external USB drives. You can connect an encrypted external drive to the NAS, and the data stored on that drive will be encrypted. This provides an additional layer of security for data stored on external drives.
    5. AES 256-bit Volume-based Encryption: The NAS also supports volume-based encryption using the AES 256-bit algorithm. This means that you can encrypt an entire storage volume on the NAS, including all files and folders stored within it. This ensures comprehensive protection for sensitive data stored on the NAS.

    Overall, the encryption capabilities of the QNAP Turbo Station TS-259 Pro / TS-259 Pro+ provide robust security measures to protect sensitive data during file access and transmission. By encrypting shared folders, network data, remote replication, external drives, and entire volumes, the NAS ensures that unauthorized users cannot access or decipher the encrypted data without the encryption keys.
