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 Asustor 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 inadequate cooling or high ambient temperatures impact data loss risks for NAS Asustor LOCKERSTOR 8 devices?

Yes, inadequate cooling or high ambient temperatures can impact data loss risks for NAS Asustor LOCKERSTOR 8 devices.

NAS devices generate heat while operating, and if the cooling system is not sufficient or the ambient temperature is too high, it can lead to overheating. Overheating can cause various issues such as component failure, data corruption, and even complete data loss.

When the temperature inside the NAS exceeds the recommended operating range, it can negatively affect the hard drives' performance and reliability. High temperatures can cause the hard drives to spin slower, increase the chances of read/write errors, and reduce their lifespan. In extreme cases, prolonged exposure to high temperatures can lead to hard drive failure and permanent data loss.

To minimize the risks, it is important to ensure proper cooling for the NAS device. This can be achieved by providing adequate ventilation, maintaining a cool environment, and using additional cooling solutions such as fans or cooling pads if necessary. Regularly monitoring the temperature of the NAS and taking appropriate actions if it exceeds safe levels can also help mitigate the risks of data loss.

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

Although NAS LOCKERSTOR 8 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 Asustor LOCKERSTOR 8. 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.

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 Asustor LOCKERSTOR 8 network-attached storage keeps OS Linux 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 logically damaged NAS Asustor LOCKERSTOR 8 device. However, the success of the recovery depends on the extent of the damage and the specific recovery methods used.

      Here are some steps you can take to recover data from a logically damaged NAS device:

      1. Disconnect the NAS device from the network and power source to prevent further damage.
      2. Consult the manufacturer's documentation or support resources for any specific recovery procedures or tools.
      3. If the NAS device is still accessible, try to access the data through alternate methods such as connecting the device directly to a computer via USB or SATA.
      4. If the device is not accessible, you may need to remove the hard drives from the NAS and connect them to a computer using a USB adapter or by installing them internally.
      5. Use data recovery software to scan the hard drives and attempt to recover the lost data. There are several reliable data recovery software options available, such as EaseUS Data Recovery Wizard, Recuva, or R-Studio.
      6. If the data recovery software is unable to recover the data, you may need to consult a professional data recovery service. They have specialized equipment and expertise to recover data from physically damaged storage devices.

      It's important to note that attempting data recovery on your own may further damage the device or the data. If the data is critical and valuable, it is recommended to seek professional help from a reputable data recovery service.
