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 Synology 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 overheating or improper ventilation cause data loss on NAS Synology RackStation RS212 devices?

Yes, overheating or improper ventilation can potentially cause data loss on NAS Synology RackStation RS212 devices. NAS devices generate heat during operation, and if they are not properly ventilated or if the cooling system fails, the internal components can overheat. Overheating can lead to various issues, including data corruption or damage to the hard drives, which can result in data loss.

It is important to ensure that the NAS device is placed in a well-ventilated area and that the cooling system is functioning properly. Regularly cleaning the fans and ensuring that the airflow is not obstructed can help prevent overheating. Additionally, it is recommended to monitor the temperature of the NAS device and take appropriate measures if it exceeds safe levels, such as adding additional cooling or relocating the device to a cooler environment.

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

Although NAS RackStation RS212 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.
