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 regular data integrity checks help prevent data loss in NAS QNAP TVS-871U-RP devices?

Yes, regular data integrity checks can help prevent data loss in NAS QNAP TVS-871U-RP devices. These checks typically involve verifying the integrity of the data stored on the device by comparing it to a known checksum or hash value. If any discrepancies are found, it can indicate data corruption or loss.

By performing regular data integrity checks, you can identify and address any potential issues early on, minimizing the risk of data loss. Additionally, some NAS devices, including QNAP TVS-871U-RP, offer features like RAID (Redundant Array of Independent Disks) which provide data redundancy and fault tolerance to further protect against data loss.

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

Although NAS TVS-871U-RP 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 TVS-871U-RP. 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

TVS-871U-RP has 8 HDD slots, and it supports the following array types:

  • RAID 50;
  • RAID 60;
  • 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.

  4. At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The QNAP TVS-871U-RP 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.

    Can data recovery from a NAS QNAP TVS-871U-RP device be done if the device is not responding or freezing frequently?

      Data recovery from a NAS QNAP TVS-871U-RP device can still be possible even if the device is not responding or freezing frequently. However, it may require professional assistance and specialized data recovery tools.

      Here are a few steps you can try before seeking professional help:

      1. Power cycle: Disconnect the power supply from the NAS device, wait for a few minutes, and then reconnect it. This can sometimes resolve temporary freezing issues.
      2. Check network connectivity: Ensure that the NAS device is properly connected to the network and that there are no network-related issues causing the freezing or unresponsiveness.
      3. Update firmware: Check if there are any firmware updates available for your QNAP NAS device. Updating the firmware may fix any known issues that could be causing the freezing problem.
      4. Hardware check: If the freezing issue persists, it could be due to a hardware problem. Check if all the hardware components (such as hard drives, RAM, power supply) are properly seated and functioning correctly. If any component is faulty, it may need to be replaced.

      If none of these steps resolve the issue, it is recommended to contact a professional data recovery service provider who specializes in NAS devices. They will have the expertise and tools necessary to recover data from a non-responsive or frequently freezing NAS device.
