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.

How can a NAS Buffalo TeraStation WS5420RN16S9 device's power management settings impact data availability and potential loss?

The power management settings of a NAS Buffalo TeraStation WS5420RN16S9 device can impact data availability and potential loss in the following ways:

Sleep Mode: If the NAS device is set to enter sleep mode after a certain period of inactivity, it can lead to slower response times when accessing data. This can impact data availability as users may experience delays in accessing files and folders.
Disk Spin-down: Some NAS devices offer the option to spin down idle hard drives to conserve power. While this can reduce energy consumption, it can also result in a delay when accessing data as the drives need to spin up before they can be accessed. If a drive fails to spin up properly, it can lead to potential data loss or corruption.
Scheduled Power Off: NAS devices often provide the option to schedule automatic power off during specific times, such as outside office hours. While this can save power, it means that data will not be accessible during those periods, potentially impacting data availability.
Power Interruptions: In regions with unstable power supply or frequent power outages, the NAS device's power management settings can impact data availability and potential loss. If the device is not configured to handle power interruptions properly, it may result in data corruption or loss due to improper shutdowns.

To mitigate these risks, it is essential to carefully configure the power management settings of the NAS device. It is recommended to strike a balance between power savings and data availability by setting appropriate sleep mode timers, disk spin-down settings, and scheduled power off periods. Additionally, implementing an uninterruptible power supply (UPS) can help protect the NAS device from sudden power outages, ensuring proper shutdown procedures are followed to minimize the risk of data loss or corruption.

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

Although NAS TeraStation WS5420RN16S9 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 WS5420RN16S9 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.
