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 VS-4016 Pro devices?

There are several risks of data loss due to firmware or software malfunctions in NAS QNAP VS-4016 Pro devices. Some of the key risks include:

  1. Corruption of data: Firmware or software malfunctions can lead to data corruption, making the stored data unreadable or inaccessible.
  2. System instability: Malfunctions in firmware or software can cause the NAS device to become unstable, leading to crashes or system failures. This can result in data loss if the device is not properly shut down or if data is being written at the time of the failure.
  3. Incompatibility issues: Firmware or software updates may not be fully compatible with the NAS device, leading to compatibility issues and potential data loss.
  4. Security vulnerabilities: Malfunctions in firmware or software can introduce security vulnerabilities, making the NAS device susceptible to hacking or unauthorized access. This can result in data breaches or data loss.
  5. Data migration issues: Firmware or software malfunctions can complicate the process of migrating data from one NAS device to another, potentially leading to data loss during the migration process.
  6. Limited recovery options: In case of firmware or software malfunctions, the recovery options may be limited, especially if the data is not properly backed up. This can result in permanent data loss.

To mitigate these risks, it is important to regularly update the firmware and software of the NAS device, maintain proper backups of the data, and ensure the security of the device by implementing strong access controls and encryption measures.

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

Although NAS VS-4016 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.

VS-4016 Pro has 4 HDD slots, and it supports the following array types:

  • RAID 6;
  • RAID 5;
  • RAID 10;
  • RAID 0;
  • RAID 1;
  • JBOD;

NAS supports:

  • ZFS;
  • 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-4016 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.
