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 Buffalo 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 virtualization technologies impact data loss risks in NAS Buffalo TeraStation WS5420RN40S9 devices?

Yes, virtualization technologies can impact data loss risks in NAS Buffalo TeraStation WS5420RN40S9 devices. By using virtualization, you can create multiple virtual machines (VMs) on a single physical server, allowing for better utilization of resources and improved data protection.

Here are a few ways virtualization can help mitigate data loss risks:

Improved backup and disaster recovery: Virtualization enables you to take snapshots of VMs, allowing for quick and easy backups. These snapshots can be used to restore data in case of accidental deletion, hardware failure, or other data loss events.
High availability and fault tolerance: Virtualization platforms often offer features like live migration and high availability, which allow VMs to be moved to different physical servers without any downtime. This ensures that if one physical server fails, the VMs can be quickly and automatically moved to another server, minimizing the risk of data loss.
Isolation and containment: Virtual machines can be isolated from each other, preventing any potential malware or software issues in one VM from affecting others. This containment helps in reducing the risk of data loss due to malware attacks or software misconfigurations.
Testing and development environments: With virtualization, you can easily create and manage multiple VMs for testing and development purposes. This allows you to test software updates, patches, or configuration changes without risking the production environment. In case of any issues or data loss, it will only affect the VM and not the entire NAS device.

It's important to note that while virtualization can help mitigate data loss risks, it is not a substitute for proper backup and disaster recovery strategies. Regular backups, off-site storage, and other data protection measures should still be implemented to ensure comprehensive data loss prevention.

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

Although NAS TeraStation WS5420RN40S9 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.

This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:

Overwriting during the recovery process;
Loss resulting from bad sectors;
User mistakes.

To create an image, do the following:

Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.

Where are user’s files stored?

The Buffalo TeraStation WS5420RN40S9 network-attached storage keeps Windows Storage Server 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.
