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 common causes of data loss in NAS QNAP VS-8148U-RP Pro+ devices?

The common causes of data loss in NAS QNAP VS-8148U-RP Pro+ devices can include:

  1. Hardware failure: This can include issues with the hard drives, power supply, or other components of the NAS device. If any of these components fail, it can result in data loss.
  2. Human error: Accidental deletion or formatting of files or folders can lead to data loss. It is important to be cautious when managing files on the NAS device to avoid such mistakes.
  3. Software or firmware issues: Problems with the operating system or firmware of the NAS device can cause data loss. This can include software bugs, compatibility issues, or corruption of the system files.
  4. Power outages or surges: Sudden power failures or voltage fluctuations can result in data loss if the NAS device is not properly protected by a UPS (Uninterruptible Power Supply).
  5. Virus or malware infections: If the NAS device gets infected with a virus or malware, it can lead to data corruption or loss. It is important to have proper security measures in place to protect the device from such threats.
  6. Natural disasters or physical damage: Fire, flood, or physical damage to the NAS device can result in complete data loss if the storage media gets damaged beyond recovery.

To mitigate the risk of data loss, it is recommended to regularly backup the data stored on the NAS device to an external storage or cloud-based backup solution.

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

Although NAS VS-8148U-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.

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

  • 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 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-8148U-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.
