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 encryption safeguard data stored on NAS QNAP VS-4116 Pro+ devices?

Yes, encryption can safeguard data stored on QNAP VS-4116 Pro+ devices. QNAP NAS devices provide various encryption options to protect data at rest, such as AES 256-bit encryption. This encryption ensures that even if someone gains unauthorized access to the NAS device or its hard drives, they won't be able to view or access the encrypted data without the encryption key. It is important to enable encryption on the NAS device and choose a strong encryption key to enhance the security of the stored data.

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

Although NAS VS-4116 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-4116 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.

VS-4116 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-4116 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.

      Yes, it is possible to recover data from a physically damaged QNAP NAS device. However, the success of the data recovery process will depend on the extent of the physical damage and the specific circumstances of the situation.

      If the damage is limited to the hardware components and does not affect the storage drives, it may be possible to repair or replace the damaged parts and access the data. In such cases, it is recommended to contact a professional data recovery service that specializes in NAS devices.

      If the storage drives themselves are damaged, the data recovery process becomes more complex. In such cases, specialized data recovery techniques may be required to retrieve the data from the damaged drives. Again, it is advisable to seek the assistance of a professional data recovery service with experience in handling NAS devices.

      It is important to note that attempting DIY data recovery methods on physically damaged devices can potentially worsen the situation and lead to permanent data loss. Therefore, it is generally recommended to consult with experts in data recovery to maximize the chances of successful data retrieval.
