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 Thecus also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.

Are there any specific system logs or event notifications to monitor for early detection of data loss on NAS Thecus N7510 devices?

The Thecus N7510 NAS device has a built-in system log that records various events and activities on the device. Monitoring this log can help in detecting data loss or any other issues. Some specific system logs and event notifications to monitor for early detection of data loss on Thecus N7510 devices include:

  1. RAID Status: Check the RAID status log regularly to ensure that the RAID array is functioning properly. Any errors or warnings related to the RAID configuration can indicate potential data loss.
  2. Disk Health: Monitor the disk health log to detect any issues with the hard drives. Errors or warnings related to disk failures or bad sectors can be early indicators of data loss.
  3. File System Errors: Keep an eye on the file system log for any errors or inconsistencies. File system errors can lead to data corruption or loss.
  4. Backup Status: If you have set up backups on the NAS, monitor the backup status log to ensure that backups are running successfully. Failed backups or incomplete backups can indicate potential data loss.
  5. Network Connectivity: Check the network connectivity log to ensure that the NAS is accessible and connected to the network. Network issues can lead to data loss if the NAS becomes inaccessible or disconnected.
  6. User Activity: Monitor user activity logs to detect any suspicious or unauthorized access to the NAS. Unusual user activity can be a sign of data breach or loss.

It is recommended to regularly review these logs and set up event notifications or alerts to receive immediate notifications in case of any critical events. Additionally, keeping regular backups of the data stored on the NAS can help mitigate the risk of data loss.

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

Although NAS N7510 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 Thecus N7510. 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.

  • RAID 0;
  • RAID 1;
  • RAID 5;
  • RAID 6;
  • RAID 10;
  • JBOD;

NAS supports:

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 Thecus N7510 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.

    Is it possible to recover data from a NAS Thecus N7510 device that has been physically damaged due to a power surge?
    • Hetman Software

      It is possible to recover data from a physically damaged NAS device, but it depends on the extent of the damage. If the power surge only affected the power supply or other components, it may be possible to repair or replace those parts and retrieve the data. However, if the damage is severe and has affected the storage drives or other critical components, data recovery may be more challenging or even impossible.

      In such cases, it is recommended to consult with a professional data recovery service. They have specialized tools and expertise to recover data from damaged storage devices. They can assess the extent of the damage and provide a better understanding of the chances of successful data recovery.
