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-2212 Pro+

QNAP VS-2212 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-2212 Pro+.

How to recover data from NAS QNAP VS-2212 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 improper shutdown or unclean system reboots lead to data loss on NAS QNAP VS-2212 Pro+ devices?

Improper shutdown or unclean system reboots can potentially lead to data loss on any device, including NAS devices like the QNAP VS-2212 Pro+. When a NAS device is abruptly powered off or rebooted without following the proper shutdown procedure, it can cause data corruption or damage to the file system.

NAS devices typically use a file system like EXT4 or Btrfs, which can be sensitive to unexpected power loss or improper shutdowns. These file systems rely on metadata structures and journaling to maintain data integrity. If the file system is not cleanly unmounted or if the metadata structures get corrupted due to an improper shutdown, it can result in data loss or inaccessibility.

To minimize the risk of data loss, it is important to follow the proper shutdown procedure recommended by the manufacturer. This usually involves using the NAS management interface or software to initiate a shutdown or reboot. Additionally, ensuring that the NAS device is connected to a reliable power source with a backup power supply (UPS) can help protect against sudden power outages.

It is also recommended to regularly backup important data stored on the NAS device to an external storage or cloud service. This way, even if data loss occurs, you can restore your files from the backups.

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

Although NAS VS-2212 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-2212 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-2212 Pro+ has 2 HDD slots, and it supports the following array types:

  • RAID 1;

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-2212 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.
