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 the use of specific data recovery software or services impact the success rate of data retrieval from NAS Buffalo TeraStation TS3420DN3204 devices?

Yes, the use of specific data recovery software or services can impact the success rate of data retrieval from NAS Buffalo TeraStation TS3420DN3204 devices. The success of data retrieval depends on various factors such as the type of data loss, the extent of damage to the device, and the effectiveness of the recovery software or service being used.

Using reliable and specialized data recovery software or services designed for NAS devices can significantly improve the chances of successful data retrieval. These tools and services are specifically developed to handle the complexities of NAS systems and have advanced algorithms to recover data from various storage configurations.

However, it is important to note that not all data recovery software or services are created equal. Some may have better compatibility and success rates with specific NAS devices like the Buffalo TeraStation TS3420DN3204. It is recommended to research and choose reputable software or services that have a proven track record in recovering data from NAS devices, and preferably those that have experience with Buffalo TeraStation models.

Additionally, it is crucial to follow proper procedures and precautions while attempting data recovery to avoid further damage to the device and data loss. If the data loss is critical or the device is physically damaged, it is advisable to seek professional data recovery services as they have the expertise and specialized tools to handle complex situations.

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

Although NAS TeraStation TS3420DN3204 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.

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 TS3420DN3204 network-attached storage keeps OS Linux 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.

  The Buffalo TeraStation TS3420DN3204 devices typically use the XFS file system. This file system is designed for high-performance and scalability, making it well-suited for NAS devices. However, it is worth noting that the file system used does not directly affect data recovery. Data recovery is primarily dependent on factors such as the underlying storage media, the nature of the data loss, and the tools and techniques used for recovery.
