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.

How can regular software updates and patches enhance the security and stability of NAS QNAP Turbo Station TS-1231XU devices?

Regular software updates and patches can enhance the security and stability of NAS QNAP Turbo Station TS-1231XU devices in the following ways:

1. Security Fixes: Updates and patches often include security fixes that address vulnerabilities and weaknesses in the system. By regularly updating the software, you ensure that any known security issues are resolved, reducing the risk of unauthorized access, data breaches, or malware attacks.
2. Bug Fixes: Updates and patches also fix bugs and software glitches that may affect the stability and performance of the NAS device. These fixes can improve system reliability, prevent crashes, and enhance overall performance.
3. New Features: Software updates may introduce new features or functionalities that can improve the usability and efficiency of the NAS device. These updates can enhance user experience, provide additional options for data management, or introduce compatibility with new technologies.
4. Compatibility: Updates and patches ensure that the NAS device remains compatible with the latest hardware, software, and network standards. This compatibility is crucial for maintaining a secure and stable environment, as outdated software may have compatibility issues that can be exploited by attackers.
5. Security Enhancements: Software updates often include security enhancements such as improved encryption algorithms, stronger authentication mechanisms, or additional security protocols. These enhancements can protect data stored on the NAS device and secure data transfers between the NAS and other devices.
6. Vulnerability Management: Regular updates and patches allow the NAS manufacturer to proactively manage vulnerabilities and respond to emerging threats. By promptly addressing security issues, the manufacturer can minimize the window of opportunity for attackers and provide a more secure environment for users.

It is important to regularly check for software updates and patches provided by the NAS manufacturer and apply them promptly to ensure the highest level of security and stability for your QNAP Turbo Station TS-1231XU device.

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

Although NAS Turbo Station TS-1231XU 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 Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with QNAP Turbo Station TS-1231XU. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a QNAP

Turbo Station TS-1231XU has 12 HDD slots, and it supports the following array types:

• RAID 50;
• RAID 60;
• RAID 5;
• RAID 6;
• RAID 10;
• RAID 0;
• RAID 1;
• JBOD;

NAS supports:

• ZFS;
• EXT4;
• EXT3;
• exFAT;
• 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.

   

4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

   

Where are user’s files stored?

The QNAP Turbo Station TS-1231XU network-attached storage keeps QTS (QuTS hero) 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.
