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 the use of specific file-sharing protocols impact data loss risks on NAS Buffalo TeraStation TS3410RN0802 devices?

The use of specific file-sharing protocols can impact data loss risks on NAS Buffalo TeraStation TS3410RN0802 devices in several ways:

1. Access Control: Different file-sharing protocols have varying levels of access control mechanisms. Some protocols, like FTP, may provide less granular control over user permissions, increasing the risk of unauthorized access and potential data loss. It is important to choose a protocol that offers robust access control features to minimize the risk of data loss.
2. Encryption: File-sharing protocols differ in their support for encryption. Protocols like FTP may transmit data in plain text, making it vulnerable to interception and unauthorized access. Using protocols such as SFTP (SSH File Transfer Protocol) or HTTPS (HTTP Secure) can help mitigate the risk of data loss by encrypting data during transmission.
3. Data Integrity: Certain file-sharing protocols may not provide mechanisms for ensuring data integrity during transmission. Without proper integrity checks, data corruption or loss may go undetected, leading to potential data loss. Choosing protocols that support integrity checks, such as checksums or hashing, can help identify and mitigate data loss risks.
4. Network Vulnerabilities: Some file-sharing protocols may be more susceptible to network vulnerabilities, such as man-in-the-middle attacks or packet sniffing. These vulnerabilities can expose data to unauthorized access and increase the risk of data loss. Selecting protocols that have built-in security features, such as secure authentication and encryption, can help mitigate these risks.
5. Compatibility and Interoperability: The choice of file-sharing protocol can impact compatibility and interoperability with different operating systems and devices. Incompatibilities may lead to data loss if files become corrupted or inaccessible during transfer or sharing. It is essential to ensure that the chosen protocol is supported by all relevant devices and operating systems to minimize the risk of data loss.

To reduce data loss risks on NAS Buffalo TeraStation TS3410RN0802 devices, it is advisable to choose file-sharing protocols that offer robust access control, encryption, data integrity checks, network security features, and compatibility with the intended environment. Additionally, implementing regular backups and following best practices for data management can further enhance data loss prevention on these devices.

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

Although NAS TeraStation TS3410RN0802 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.

   How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Buffalo TeraStation TS3410RN0802. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.

How to recover data from a Buffalo

TeraStation TS3410RN0802 has 2 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• JBOD;

NAS supports:

• exFAT, VFAT, FAT 12 / 16 / 32;
• NTFS / ReFS;
• APFS / HFS+;
• Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
• VMFS / HikvisionFS;

Safe recovery from disk images

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:

1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

2. Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.

3. 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.

   

4. 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 TS3410RN0802 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.
