How to recover data from NAS QNAP Turbo Station TS-433

QNAP Turbo Station TS-433 NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from Turbo Station TS-433.

How to recover data from NAS QNAP Turbo Station TS-433

Recover data from damaged RAID arrays inaccessible from a computer.

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 are the risks of data loss due to firmware or software malfunctions in NAS QNAP Turbo Station TS-433 devices?

There are several risks of data loss due to firmware or software malfunctions in NAS QNAP Turbo Station TS-433 devices:

  1. Corruption of data: Firmware or software malfunctions can lead to data corruption, making the files and folders stored on the NAS inaccessible or unusable.
  2. System instability: Malfunctioning firmware or software can cause the NAS device to become unstable, leading to frequent crashes or system freezes. This can result in data loss or damage.
  3. Disk failure: In some cases, firmware or software issues can cause the NAS device to mishandle the connected hard drives, leading to disk failures. This can result in permanent data loss if the drives are not properly backed up.
  4. Incompatibility with third-party applications: Firmware or software malfunctions can cause compatibility issues with certain third-party applications or plugins installed on the NAS. This can lead to data loss or the inability to access specific files or services.
  5. Vulnerability to security threats: Malfunctioning firmware or software may contain security vulnerabilities that can be exploited by hackers or malware. This can result in unauthorized access, data breaches, or even complete data loss.

To mitigate these risks, it is important to regularly update the firmware and software of the NAS device, maintain proper backups of critical data, and follow best practices for data security and system maintenance.

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

Although NAS Turbo Station TS-433 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.
