How to recover data from NAS QNAP Turbo Station TS-873U-RP

QNAP Turbo Station TS-873U-RP 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-873U-RP.

How to recover data from NAS QNAP Turbo Station TS-873U-RP

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.

Are there any recommended steps to take after detecting or suspecting data loss on a NAS QNAP Turbo Station TS-873U-RP device?

Yes, there are several recommended steps to take after detecting or suspecting data loss on a QNAP Turbo Station TS-873U-RP NAS device. Here are some steps you can follow:

  1. Stop using the NAS: As soon as you suspect data loss, it's crucial to stop using the NAS immediately. Continuing to use the device may overwrite the lost data, making it harder or impossible to recover.
  2. Disconnect from the network: Disconnect the NAS from the network to prevent any further data loss or corruption. This will help ensure that no automatic synchronization or backup processes overwrite the lost data.
  3. Contact QNAP support: Reach out to QNAP support for assistance. They can provide guidance specific to your device and help you troubleshoot the issue. QNAP's support team may be able to guide you through recovery steps or recommend professional data recovery services.
  4. Check hardware and connections: Ensure that all hardware components are properly connected and functioning. Check cables, power supply, and any storage drives for any signs of damage or failure.
  5. Perform basic troubleshooting: Follow any troubleshooting steps recommended by QNAP support. This may include restarting the device, updating firmware, or performing a system reset.
  6. Attempt data recovery: If you have backups, restore the data from the backup source. If you don't have backups, and the data is critical, consider seeking professional data recovery services. QNAP may be able to recommend trusted data recovery providers.
  7. Review and improve backup strategy: After recovering the data or setting up the NAS again, review your backup strategy. Ensure that you have regular backups in place to prevent future data loss incidents. Consider using multiple backup methods, such as off-site backups or cloud storage, for added redundancy.

Remember, data recovery success depends on various factors, including the nature of the data loss and the actions taken after detection. It's always recommended to consult with professionals or follow QNAP's guidance for the best chance of recovering your lost data.

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

Although NAS Turbo Station TS-873U-RP 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-873U-RP 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.
