How to recover data from QNAP VS-12156U-RP Pro+ NAS

Is your network drive gone, and you are wondering what to do? Has a RAID system crashed, and your files are no longer accessible? Does your device display an error while booting? Have you accidentally rebuilt your RAID system? Are several hard disks out of order?

How to recover data from NAS QNAP VS-12156U-RP Pro+

QNAP VS-12156U-RP Pro+ NAS Data Recovery in 2024

In this step-by-step tutorial, we’ll show you how to rebuild your RAID and recover data from VS-12156U-RP Pro+.

How to recover data from NAS QNAP VS-12156U-RP Pro+

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.

Can regular data integrity checks help prevent data loss in NAS QNAP VS-12156U-RP Pro+ devices?

Yes, regular data integrity checks can help prevent data loss in NAS QNAP VS-12156U-RP Pro+ devices. Data integrity checks ensure that the data stored on the device is accurate and has not been corrupted or modified unintentionally.

QNAP NAS devices usually offer built-in data integrity features such as checksums and RAID configurations. Checksums verify the integrity of data by generating a unique hash value for each file, and this value is checked periodically to ensure that the data has not been altered.

RAID configurations, on the other hand, provide redundancy by distributing data across multiple hard drives. This redundancy helps in protecting against data loss in case of drive failures.

Additionally, regular backups of the data stored on the NAS device are crucial for preventing data loss. Backing up the data to an external storage device or to the cloud ensures that even if the NAS device fails or experiences data corruption, a copy of the data is available for recovery.

It is important to note that while data integrity checks and backups can help prevent data loss, they do not guarantee 100% protection. It is always recommended to have a comprehensive data protection strategy that includes multiple layers of redundancy and regular testing of backups to ensure their integrity.

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

Although NAS VS-12156U-RP 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 VS-12156U-RP Pro+ 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.

      Recovering data from a physically damaged NAS device can be challenging, but it is not impossible. If the internal components of the NAS, such as the hard drives, are still intact, there is a chance to recover the data.

      Here are a few steps you can take:

      1. Assess the damage: Examine the NAS device and check for any visible physical damage. If the hard drives or other internal components are visibly damaged, it may require professional data recovery services.
      2. Remove the hard drives: If the hard drives are undamaged, remove them from the NAS enclosure carefully. Handle them with caution to prevent further damage.
      3. Connect the hard drives: Connect the undamaged hard drives to a computer using a SATA-to-USB adapter or by installing them directly into a computer. Ensure that you have the necessary cables and connectors.
      4. Data recovery software: Use data recovery software like Recuva, TestDisk, or GetDataBack to attempt to recover the data from the connected hard drives. These tools can scan the drives for recoverable files and allow you to restore them to another storage device.
      5. Professional data recovery services: If the above steps do not work or the hard drives are physically damaged, consider contacting professional data recovery services. They have specialized tools and expertise to recover data from physically damaged devices. However, note that professional data recovery can be expensive.

      Remember, data recovery from physically damaged devices is not guaranteed, and there is always a risk of further damage. It is advisable to consult with a professional data recovery service for the best chance of recovering your data.
