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 inadequate cooling or high ambient temperatures impact data loss risks for NAS QNAP VS-4008 Pro devices?

Yes, inadequate cooling or high ambient temperatures can indeed impact data loss risks for NAS QNAP VS-4008 Pro devices.

NAS devices generate heat during operation, and if they are not adequately cooled, the internal components can overheat. This can lead to various issues, including data corruption or even hardware failure. The high temperatures can cause the hard drives to degrade faster, leading to potential data loss.

Additionally, high ambient temperatures can exacerbate the cooling problem. If the surrounding environment is already hot, it becomes more challenging for the NAS device to dissipate heat effectively. This can further increase the risk of overheating and subsequent data loss.

To mitigate these risks, it is essential to ensure proper cooling for the NAS device. This can be achieved by providing adequate ventilation, using cooling fans or heat sinks, and avoiding placing the NAS in areas with high ambient temperatures. Regular maintenance and cleaning of the device's cooling system can also help prevent overheating and potential data loss.

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

Although NAS VS-4008 Pro 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.
