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.

What are the common causes of data loss in NAS QNAP TL-R1620Sep-RP devices?

There are several common causes of data loss in NAS QNAP TL-R1620Sep-RP devices. Some of these causes include:

Hardware failure: This can occur due to issues with the hard drives, power supply, or other components of the NAS device. Hardware failures can lead to data corruption or complete loss of data.
Power surges or outages: Sudden power surges or outages can cause the NAS device to shut down improperly, leading to data loss or corruption.
Accidental file deletion: Users may accidentally delete files or folders from the NAS, resulting in permanent data loss if there are no backups available.
Viruses and malware: If the NAS device gets infected with viruses or malware, it can lead to data loss or corruption.
Human error: Mistakes made by users, such as formatting the wrong drive or performing incorrect configurations, can result in data loss.
Natural disasters: Events like floods, fires, or earthquakes can damage the NAS device and cause data loss if proper precautions are not taken.
Theft or physical damage: If the NAS device is stolen or physically damaged, it can result in the loss of data stored on it.

To prevent data loss, it is essential to regularly backup data, implement RAID configurations, use surge protectors, keep the NAS device in a secure location, and install antivirus software to protect against malware.

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

Although NAS TL-R1620Sep-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:

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.
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.
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
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.
