Why Regular Data Recovery Tools Can’t Restore Files from RAID

Conventional hard drives store user data by writing it sequentially across the disk surface, which means an entire file is typically located on a single drive. In contrast, when data is written to a RAID array, each file is split into multiple fragments. These fragments are then distributed and written in sequence across all the drives in the array. Depending on the configuration, fragment sizes can range from 2 KB to 2 MB, so every file is physically stored across several disks at once.

This approach significantly increases read and write performance — after all, writing two halves of a 1 GB file to two drives simultaneously is much faster than writing the full 1 GB to a single disk. However, this same mechanism makes file recovery far more complex.

Different RAID levels use different methods to distribute and protect data. On top of that, manufacturers like Thecus often add their own proprietary structures and variations. As a result, data can be written to disks in many different formats, and each requires a specific approach during recovery.

Can power outages or surges affect data stored in NAS Thecus N7700PRO v2 devices?

Yes, power outages or surges can potentially affect data stored in NAS (Network Attached Storage) devices such as Thecus N7700PRO v2. During a power outage, if the NAS is not connected to a backup power source (like an uninterruptible power supply or UPS), the sudden loss of power can lead to an improper shutdown of the device. This improper shutdown can cause data corruption or loss.

Similarly, power surges can also damage the NAS hardware and potentially lead to data loss or corruption. Power surges occur when there is a sudden increase in electrical voltage, which can overload the electronic components of the NAS and cause them to fail.

To protect the data stored in NAS devices, it is recommended to use a UPS to provide backup power during outages and to use surge protectors to safeguard against power surges. Additionally, regularly backing up the data stored in the NAS to an external location or cloud storage can provide an extra layer of protection.

How to Remove Hard Disks from Your NAS and Connect Them to a PC

Although the NAS N7700PRO v2 can be accessed over the network, you still need to remove its hard disks and connect them directly to a Windows PC. Only then can the recovery software properly scan and analyze the drives. Follow these steps:

Power off the NAS and disconnect it from the power source.

WARNING! Before removing any drives, carefully read the device manual. Improper actions may damage both the NAS enclosure and the hard disks in the RAID array.
Remove the hard disks one by one, gently sliding each drive out of its slot. Remember that hard disks are highly sensitive: any impact or drop can cause serious physical damage.
Label each hard disk according to its position inside the NAS. The order of the drives is crucial for correct RAID reconstruction.
Connect the drives to your computer. In this video, we explain which ports you can use to connect hard disks and what to do if your PC does not have enough free connectors.

Overwriting during the recovery process;
Additional data loss caused by bad sectors;
User errors.

To create a disk image, follow these steps:

Ensure you have enough free space to store the image. Its size will typically match the size of the original disk.
In the main window, select the target disk and choose Tools - Save Disk. You can also select multiple disks if needed.
When the Image Creation Wizard opens, select whether you want to save the entire disk or only a specific region. Adjust the settings and click Next.
Choose the directory where the image will be saved. You may select any available disk connected to your PC or upload the image via FTP.

Where Are the User’s Files Actually Stored?

The Thecus N7700PRO v2 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, data recovery from a NAS Thecus N7700PRO v2 device can be attempted even if the device is showing signs of disk or storage media errors. However, it is important to note that the success of data recovery depends on the extent of the errors and the condition of the storage media.
  Here are a few steps you can take to attempt data recovery:
  Identify the cause of the errors: Determine whether the errors are due to physical damage to the disks or logical errors within the NAS system.
  Assess the severity of the errors: If the errors are minor and limited to a few sectors, you can try using disk repair tools or software provided by Thecus to fix the errors. However, if the errors are severe or widespread, professional data recovery services may be required.
  Contact professional data recovery services: If the data on the NAS device is critical and you are unable to recover it using built-in tools, it is recommended to contact professional data recovery services. They have specialized equipment and expertise to handle complex data recovery scenarios.
  Avoid further damage: To prevent further damage to the storage media, it is advisable to avoid using the NAS device until the data recovery process is complete. Continued use may worsen the existing errors and reduce the chances of successful recovery.
  Remember, data recovery from a faulty NAS device can be a complex and time-consuming process. It is always recommended to have regular backups of your important data to mitigate the risk of data loss.
