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 data be lost during the process of upgrading or updating the NAS QNAP VS-6012 Pro device's firmware?

Yes, there is a possibility of data loss during the process of upgrading or updating the firmware of a NAS device like the QNAP VS-6012 Pro. While firmware updates are generally designed to be safe and preserve data, there can be unforeseen issues or errors that may cause data loss.

To minimize the risk, it is recommended to take certain precautions before updating the firmware:

  1. Backup your data: Make sure to have a backup of all important data stored on the NAS device. This can be done by copying the data to an external storage device or another location.
  2. Verify the update process: Before initiating the firmware update, carefully read the release notes or documentation provided by QNAP. Ensure you are following the correct update procedure and have a clear understanding of the steps involved.
  3. Stable power supply: Ensure that the NAS device has a stable power supply during the update process. Any power interruptions or fluctuations can potentially cause data corruption or loss.
  4. Use a stable network connection: It is recommended to have a stable and reliable network connection during the firmware update. A network interruption during the update process can also lead to data loss.
  5. Follow recommended best practices: Follow any specific instructions or recommendations provided by QNAP for updating the firmware. These may include steps like disabling certain services or applications before the update.

By taking these precautions, you can minimize the risk of data loss during the firmware update process. However, it is always a good practice to have regular backups of your data to ensure its safety.

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

Although NAS VS-6012 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.

Restoring data with Hetman RAID Recovery

Hetman Raid Recovery

This program recovers data from damaged RAID arrays and is fully compatible with QNAP VS-6012 Pro. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a QNAP

VS-6012 Pro has 6 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-6012 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.
