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 hardware upgrades or modifications lead to data loss if not properly executed on NAS QNAP TBS-453DX devices?

Yes, hardware upgrades or modifications can potentially lead to data loss if not properly executed on NAS QNAP TBS-453DX devices. This is because any mishandling or improper installation of hardware components can cause damage to the device or its storage drives, resulting in data corruption or loss.

It is crucial to follow the manufacturer's instructions and guidelines while performing any hardware upgrades or modifications on the NAS device. This may involve ensuring compatibility of the hardware components, taking necessary precautions to avoid static electricity discharge, and properly connecting and securing the components.

Additionally, it is highly recommended to have a backup of all important data before attempting any hardware modifications. This way, even if data loss occurs, you can restore the data from the backup.

If you are unsure about performing hardware upgrades or modifications yourself, it is advisable to seek professional assistance to minimize the risks of data loss.

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

Although NAS TBS-453DX 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.
