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 data be recovered from a NAS QNAP Turbo Station TS-h1886XU-RP device after a malfunction or data loss event?

Recovering data from a NAS QNAP Turbo Station TS-h1886XU-RP device after a malfunction or data loss event can be done through the following steps:

  1. Identify the cause of the malfunction: Determine whether the issue is due to hardware failure, software corruption, or accidental deletion.
  2. Contact QNAP support: Reach out to QNAP's technical support team to report the problem and seek assistance. They may provide guidance specific to your device model and help troubleshoot the issue.
  3. Check for hardware issues: Ensure that all physical connections are secure and functioning properly. If there are any signs of hardware failure (e.g., unusual noises, overheating), it may be necessary to contact a professional data recovery service.
  4. Utilize QNAP recovery tools: QNAP provides various recovery tools and utilities that can help restore data in case of software-related issues. These tools can be downloaded from the QNAP website and used according to the provided instructions.
  5. Restore from backups: If you have previously set up a backup system, you can restore the lost data from your backup files. QNAP NAS devices support various backup methods, including local backups, remote backups, and cloud backups. Refer to QNAP's documentation or support for guidance on how to restore data from backups.
  6. Professional data recovery services: If the data loss is significant and cannot be recovered using the above methods, it may be necessary to contact a professional data recovery service. These services specialize in recovering data from damaged or malfunctioning storage devices and may have specialized tools and techniques to retrieve data from a QNAP NAS.

Note: It is crucial to avoid further writes or modifications to the NAS device after data loss to prevent overwriting the lost data.

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

Although NAS Turbo Station TS-h1886XU-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-h1886XU-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.
